<p>Msmith: </p> <hr /> <div>== Xiph.Org Application as a mentoring organization ==<br /> <br /> We need to apply for consideration as a mentoring organization 2008 March 3-12. Google lists the following questions in their [http://code.google.com/soc/2008/faqs.html#0.1_org_apply faq]. Our work-in-progress answers are inline.<br /> <br /> ==== Describe your organization. ====<br /> <br /> [http://xiph.org Xiph.Org] is an open source project and non-profit corporation dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the internet and other digital distribution networks. Over the past 8 years we have developed most of the major patent-free audio and video codecs currently in use, including Vorbis, Speex, FLAC and Theora, as well as developing the Ogg streaming format, and the Icecast streaming media server.<br /> <br /> This year we are also coordinating projects for the [http://annodex.org Annodex association] under our umbrella. The [http://annodex.net/ Annodex project] <br /> is developing a set of open specifications and open source software to allow the creation of hyperlinked Webs of audio and video integrated with the text-based view of the current Web. Toward this goal, Annodex has done a great deal of work developing tools, browser plugins and convenience libraries to facilitate adoption of Xiph.Org's lower-level technology. As such the two projects have largely aligned goals, but focus on different levels in the stack.<br /> <br /> ==== Why is your organization applying to participate in GSoC 2008? What do you hope to gain by participating? ====<br /> <br /> We believe that Xiph.Org has a wide-ranging set of projects that are both challenging and educational for the students. Furthermore, they are important/useful goals for the wider technology community, and especially users of open source software.<br /> <br /> We believe that Xiph's mandate to develop multimedia standards and software is an important one, but we--of course--have limited resources. We hope that the results of GSoC will include the direct benefit of new software development, but also help grow the number of active participants in a long-term manner. Most of our core developers started as students, but just as many have moved on since their student days. Attracting and retaining students is essential to the health and sustainability of our project and is an important goal for all of us.<br /> <br /> ==== Did your organization participate in past GSoCs? If so, please summarize your involvement and the successes and challenges of your participation. ====<br /> <br /> Xiph.Org was invited to participate in GSoc in both 2006 and 2007, and informally mentored Annodex-related projects as well.<br /> <br /> In 2006, we were granted funding for 6 slots. One we weren't able to fill because our chosen students picked or were assigned to other projects. <br /> <br /> Two were [http://code.google.com/soc/xiph/about.html successful]. One, a [http://code.google.com/soc/xiph/appinfo.html?csaid=5F9265EEC6FA0611 hardware implementation of a Theora decoder]: this project produced HDL implementation of the major decoder components, to be used with a general purpose CPU, such as the open source LEON sparc implementation. Real time playback of SD content was demonstrated using these components in combination with the proprietary Nagios cpu design. Two, [http://code.google.com/soc/xiph/appinfo.html?csaid=213E2D30F095565D implementation of OggSkeleton support] in various tools. We have maintained contact with the two successful students since the program finished. One has continued to contribute code outside the GSoC term, continuing related work.<br /> <br /> The remaining three were unsuccessful through lack of necessary skills, health complications, insufficient motivation, or some combination of all of these.<br /> <br /> In 2007, we were given 2 project slots. One was an extension of the hardware decoder effort from last year. The other was helping to do R&amp;D on Xiph's next-generation audio codec, Ghost. Both were marginally successful - the students reached the minimum goals set, but little more, and did not maintain contact with Xiph.org after the program. <br /> <br /> We enjoyed our participation over the last two years. It provided needed external input, energizing our project and improving our connections to the rest of the open source community. We think we've learnt a lot about how to mentor new and upcoming contributors, and how to best screen the applications we do receive.<br /> <br /> ==== If your organization has not previously participated in GSoC, have you applied in the past? If so, for what year(s)? ====<br /> <br /> We have participated previously, in 2006 and 2007.<br /> <br /> ==== Who will your organization administrator be? Please include Google Account information. ====<br /> <br /> Michael Smith has volunteered to be the primary admin this year. Google account mlrsmith@gmail.com.<br /> <br /> ==== What license(s) does your project use? ====<br /> <br /> In general, we use a modified-BSD style license for our libraries, to enable the widest possible uses of our formats and reference implementations.<br /> <br /> Our applications are generally GPL but LGPL or (GPL-compatible) modified BSD is also acceptable.<br /> <br /> ==== What is the URL for your ideas page? ====<br /> <br /> http://wiki.xiph.org/index.php/Summer_of_Code<br /> <br /> ==== What is the main development mailing list or forum for your organization? ====<br /> <br /> We don't have a single central mailing list for all of Xiph.Org. Instead, we have per-project mailing lists; of these the most active is vorbis-dev@xiph.org. A complete listing of our lists is available at:<br /> <br /> http://lists.xiph.org/mailman/listinfo/<br /> <br /> The primary contact of the Annodex projects is [http://lists.annodex.net/ annodex-dev@lists.annodex.net]<br /> <br /> ==== What is the main IRC channel for your organization? ====<br /> <br /> Our main channel is #xiph on irc.freenode.net. We also have project channels: #vorbis, #theora, #icecast, #speex and #annodex are the major ones.<br /> <br /> ==== Does your organization have an application template you would like to see students use? If so, please provide it now. ====<br /> <br /> http://wiki.xiph.org/index.php/Summer_of_Code_Applications<br /> <br /> ==== Who will be your backup organization administrator? Please include Google Account information. ====<br /> <br /> Ralph Giles will be the backup admin if no one else volunteers. Google account giles@xiph.org.<br /> <br /> ==== Who will your mentors be? Please include Google Account information. ====<br /> <br /> * '''Mike Smith''': google account mlrsmith@gmail.com<br /> * '''Ralph Giles''': google account giles@xiph.org<br /> * '''Silvia Pfeiffer''': google account silviapfeiffer1@gmail.com<br /> * '''Christopher Montgomery''': google account xiphmont@gmail.com<br /> * '''Timothy Terriberry''': google account tterribe@vt.edu<br /> * '''Jean-Marc Valin''': google account jmvalin@gmail.com<br /> * '''Arek Korbik''': google account arkadini@gmail.com<br /> * '''Michael Dale''': google account bigmammoth@gmail.com<br /> <br /> ==== What criteria did you use to select these individuals as mentors? Please be as specific as possible. ====<br /> <br /> We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br /> <br /> The majority of the mentors we've selected are core developers on the various Xiph.Org sub-projects that they've volunteered to mentor for. They have been contributing to Xiph.Org for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br /> <br /> Mike Smith has been involved with Xiph.Org and multimedia development since 2000 and remains one of our most involved core members. He helped write major portions of the vorbis-tools suite and the icecast streaming media server. He currently works as a developer at Fluendo.com on the GStreamer multimedia framework, flumotion (a streaming media server), and other multimedia software. <br /> <br /> Ralph Giles has been involved with Xiph.Org and multimedia development since 2000. He has contributed to tool development and the Theora video codec. He handles much of the coordination and administrative work for Xiph.Org. He mentored the successful &quot;Hardware implementation of Theora decoding&quot; project in GSoC 2006 and acted as an administrator.<br /> <br /> Silvia Pfeiffer is the founder of the Annodex project and president of the Annodex Association. She is the principle author of most of the Annodex specifications, RFC 3533 and RFC 3534 describing the Ogg media format, and is heavily involved as an organizer in both the Xiph and Annodex projects. <br /> Most recently she organized the [http://www.annodex.org/events/foms2007/ FOMS] developer summit and media recording for [http://lca2007.linux.org.au/ LCA 2007]. She helped mentor the successful &quot;OggSkeleton support&quot; project in GSoC 2006 and acted as an administrator during the application process.<br /> <br /> Christopher &quot;Monty&quot; Montgomery is the founder of Xiph.org, architect and lead developer of the Ogg Vorbis general purpose audio compression format. He has been doing open source development under the Xiph name since 1999. His current work focuses on development of a next-generation audio codec. He helped mentor a project related to this in GSoC 2006.<br /> <br /> Timothy Terriberry is the author of the Theora video codec specification and the author of the theora-exp implementation. He has been an active contributor since 2003. He mentored a Theora-related project in GSoC 2006.<br /> <br /> Jean-Marc Valin is the architect and lead developer of the Speex voice codec. He has been involved in Xiph.Org since 2002. He mentored an audio codec research project in GSoC 2006.<br /> <br /> Arek Korbik is the author of the [http://xiph.org/quicktime/ Xiph QuickTime Components]. He has been a project contributor since 2005.<br /> <br /> Michael Dale is the author of the [http://metavid.org MetaVidWiki] project which implements many of the annodex and xiph technologies as an extension to mediaWiki.<br /> <br /> ==== What is your plan for dealing with disappearing students? ====<br /> <br /> Our first goal will be to provide necessary support from the community such that our students do not want to suddenly vanish. We want our students to become real members of the community, with ongoing contributions. That said, we're well aware of the possibility of a student disappearing.<br /> <br /> We intend to be reasonably strict with requiring students to keep in touch - whilst we're quite happy for them to be absent for a while if they let us know in advance, we will intend to get at least twice-weekly updates from each student. <br /> <br /> The mentors will have primary responsibility for their students, but the admins (Mike Smith and Ralph Giles) are also going to ensure that the mentors are indeed keeping track of what their students are up to. We'll ask our students to provide means for us to get in touch beyond email, where possible - phone, etc - in case we need to get in touch urgently.<br /> <br /> ==== What is your plan for dealing with disappearing mentors? ====<br /> <br /> Our mentors are all people who are major contributors to the Xiph projects - and have generally been contributing for many years. So, we think it's pretty unlikely that a mentor will disappear. However, we do have more mentors available than we expect to eventually have students (based on past years), so we're well able to take up the slack if a mentor becomes unavailable for any reason.<br /> <br /> Our admins will ensure that the mentors are keeping up with the students appropriately, and should it be absolutely necessary, we will either find another appropriate mentor, or the admins (Mike and Ralph) will take over mentoring the students directly.<br /> <br /> ==== What steps will you take to encourage students to interact with your project's community before, during and after the program? ====<br /> <br /> Xiph.Org conducts much of its development discussion and community-building on our IRC channels. We'll ask that the students be present there while they're working, where adequate network access makes that possible. We hope to make them feel that they're an important part of our community; that their contributions are really making a difference towards the goals of Xiph. <br /> <br /> We intend to be open to their contributions - whilst we're aware that initially their work may not be of a quality sufficient to go into our core codebase immediately, we'll give them write access to our repository to work on a branch. We'll ask them to be open in discussing and designing their contributions on IRC and our mailing lists. Our application template welcomes them to come and ask us questions when they're trying to write up their application. We hope that some, or even all, of the students will continue to be part of the Xiph community after SoC concludes. For those students who have not previously contributed to open source software, we'll teach them about how important community building is for the ongoing health of such projects.<br /> <br /> ==== What will you do to ensure that your accepted students stick with the project after GSoC concludes? ====<br /> <br /> We hope that the mentoring process and the experiences they have as part of GSoC will make the students interested in remaining part of Xiph, continuing development on the software they've been working on, and perhaps nurturing their patches towards inclusion in an actual release.<br /> <br /> A very important part of GSoC is for us to make them active members of the community, in particular on the irc channels and the mailing lists. Past experience tells that once they have become part of that community, they will stick around for longer.<br /> <br /> We will encourage them not to consider this just &quot;a summer job&quot;, but as being part of a real community - and doing something that is both interesting, and useful to the wider world.</div>

Please be as specific as possible. ====<br /> <br /> We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br /> <br /> The majority of the mentors we've selected are core developers on the various Xiph.Org sub-projects that they've volunteered to mentor for. They have been contributing to Xiph.Org for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br /> <br /> Mike Smith has been involved with Xiph.Org and multimedia development since 2000 and remains one of our most involved core members. He helped write major portions of the vorbis-tools suite and the icecast streaming media server. He currently works as a developer at Fluendo.com on the GStreamer multimedia framework, flumotion (a streaming media server), and other multimedia software. <br /> <br /> Ralph Giles has been involved with Xiph.Org and multimedia development since 2000. He has contributed to tool development and the Theora video codec. He handles much of the coordination and administrative work for Xiph.Org. He mentored the successful &quot;Hardware implementation of Theora decoding&quot; project in GSoC 2006 and acted as an administrator.<br /> <br /> Silvia Pfeiffer is the founder of the Annodex project and president of the Annodex Association. She is the principle author of most of the Annodex specifications, RFC 3533 and RFC 3534 describing the Ogg media format, and is heavily involved as an organizer in both the Xiph and Annodex projects. <br /> Most recently she organized the [http://www.annodex.org/events/foms2007/ FOMS] developer summit and media recording for [http://lca2007.linux.org.au/ LCA 2007]. She helped mentor the successful &quot;OggSkeleton support&quot; project in GSoC 2006 and acted as an administrator during the application process.<br /> <br /> Christopher &quot;Monty&quot; Montgomery is the founder of Xiph.org, architect and lead developer of the Ogg Vorbis general purpose audio compression format. He has been doing open source development under the Xiph name since 1999. His current work focuses on development of a next-generation audio codec. He helped mentor a project related to this in GSoC 2006.<br /> <br /> Timothy Terriberry is the author of the Theora video codec specification and the author of the theora-exp implementation. He has been an active contributor since 2003. He mentored a Theora-related project in GSoC 2006.<br /> <br /> Jan is the author of the very widely used [http://v2v.cc/~j/ffmpeg2theora/ ffmpeg2theora] transcoding tool, and maintainer of the [http://v2v.cc v2v.cc] syndication website. He has been a project contributor since 2002.<br /> <br /> Conrad Parker is the author of the [http://www.annodex.net/software/liboggz/html/ liboggz] and [http://www.annodex.net/software/libfishsound/html/ libfishsound] convenience libraries and the [http://www.metadecks.org/software/sweep/ sweep] audio editor. He is heavily involved in the Annodex project and mentored the successful &quot;OggSkeleton support&quot; project in GSoC 2006.<br /> <br /> Jean-Marc Valin is the architect and lead developer of the Speex voice codec. He has been involved in Xiph.Org since 2002. He mentored an audio codec research project in GSoC 2006.<br /> <br /> Arek Korbik is the author of the [http://xiph.org/quicktime/ Xiph QuickTime Components]. He has been a project contributor since 2005.<br /> <br /> ==== What is your plan for dealing with disappearing students? ====<br /> <br /> Our first goal will be to provide necessary support from the community such that our students do not want to suddenly vanish. We want our students to become real members of the community, with ongoing contributions. That said, we're well aware of the possibility of a student disappearing.<br /> <br /> We intend to be reasonably strict with requiring students to keep in touch - whilst we're quite happy for them to be absent for a while if they let us know in advance, we will intend to get at least twice-weekly updates from each student. <br /> <br /> The mentors will have primary responsibility for their students, but the admins (Mike Smith and Ralph Giles) are also going to ensure that the mentors are indeed keeping track of what their students are up to. We'll ask our students to provide means for us to get in touch beyond email, where possible - phone, etc - in case we need to get in touch urgently.<br /> <br /> ==== What is your plan for dealing with disappearing mentors? ====<br /> <br /> Our mentors are all people who are major contributors to the Xiph projects - and have generally been contributing for many years. So, we think it's pretty unlikely that a mentor will disappear. However, we do have more mentors available than we expect to eventually have students (based on past years), so we're well able to take up the slack if a mentor becomes unavailable for any reason.<br /> <br /> Our admins will ensure that the mentors are keeping up with the students appropriately, and should it be absolutely necessary, we will either find another appropriate mentor, or the admins (Mike and Ralph) will take over mentoring the students directly.<br /> <br /> ==== What steps will you take to encourage students to interact with your project's community before, during and after the program? ====<br /> <br /> Xiph.Org conducts much of its development discussion and community-building on our IRC channels. We'll ask that the students be present there while they're working, where adequate network access makes that possible. We hope to make them feel that they're an important part of our community; that their contributions are really making a difference towards the goals of Xiph. <br /> <br /> We intend to be open to their contributions - whilst we're aware that initially their work may not be of a quality sufficient to go into our core codebase immediately, we'll give them write access to our repository to work on a branch. We'll ask them to be open in discussing and designing their contributions on IRC and our mailing lists. Our application template welcomes them to come and ask us questions when they're trying to write up their application. We hope that some, or even all, of the students will continue to be part of the Xiph community after SoC concludes. For those students who have not previously contributed to open source software, we'll teach them about how important community building is for the ongoing health of such projects.<br /> <br /> ==== What will you do to ensure that your accepted students stick with the project after GSoC concludes? ====<br /> <br /> We hope that the mentoring process and the experiences they have as part of GSoC will make the students interested in remaining part of Xiph, continuing development on the software they've been working on, and perhaps nurturing their patches towards inclusion in an actual release.<br /> <br /> A very important part of GSoC is for us to make them active members of the community, in particular on the irc channels and the mailing lists. Past experience tells that once they have become part of that community, they will stick around for longer.<br /> <br /> We will encourage them not to consider this just &quot;a summer job&quot;, but as being part of a real community - and doing something that is both interesting, and useful to the wider world.</div>

Instead, we have per-project mailing lists; of these the most active is vorbis-dev@xiph.org. A complete listing of our lists is available at:<br /> <br /> http://lists.xiph.org/mailman/listinfo/<br /> <br /> The primary contact of the Annodex projects is [http://lists.annodex.net/ annodex-dev@lists.annodex.net]<br /> <br /> ==== What is the main IRC channel for your organization? ====<br /> <br /> Our main channel is #xiph on irc.freenode.net.

Please be as specific as possible. ====<br /> <br /> We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br /> <br /> The majority of the mentors we've selected are core developers on the various Xiph.Org sub-projects that they've volunteered to mentor for. They have been contributing to Xiph.Org for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br /> <br /> Mike Smith has been involved with Xiph.Org and multimedia development since 2000 and remains one of our most involved core members. He helped write major portions of the vorbis-tools suite and the icecast streaming media server. He currently works as a developer at Fluendo.com on the GStreamer multimedia framework, flumotion (a streaming media server), and other multimedia software. <br /> <br /> Ralph Giles has been involved with Xiph.Org and multimedia development since 2000. He has contributed to tool development and the Theora video codec. He handles much of the coordination and administrative work for Xiph.Org. He mentored the successful &quot;Hardware implementation of Theora decoding&quot; project in GSoC 2006 and acted as an administrator.<br /> <br /> Silvia Pfeiffer is the founder of the Annodex project and president of the Annodex Association. She is the principle author of most of the Annodex specifications, RFC 3533 and RFC 3534 describing the Ogg media format, and is heavily involved as an organizer in both the Xiph and Annodex projects. <br /> Most recently she organized the [http://www.annodex.org/events/foms2007/ FOMS] developer summit and media recording for [http://lca2007.linux.org.au/ LCA 2007]. She helped mentor the successful &quot;OggSkeleton support&quot; project in GSoC 2006 and acted as an administrator during the application process.<br /> <br /> Christopher &quot;Monty&quot; Montgomery is the founder of Xiph.org, architect and lead developer of the Ogg Vorbis general purpose audio compression format. He has been doing open source development under the Xiph name since 1999. His current work focuses on development of a next-generation audio codec. He helped mentor a project related to this in GSoC 2006.<br /> <br /> Timothy Terriberry is the author of the Theora video codec specification and the author of the theora-exp implementation. He has been an active contributor since 2003. He mentored a Theora-related project in GSoC 2006.<br /> <br /> Jan is the author of the very widely used [http://v2v.cc/~j/ffmpeg2theora/ ffmpeg2theora] transcoding tool, and maintainer of the [http://v2v.cc v2v.cc] syndication website. He has been a project contributor since 2002.<br /> <br /> Conrad Parker is the author of the [http://www.annodex.net/software/liboggz/html/ liboggz] and [http://www.annodex.net/software/libfishsound/html/ libfishsound] convenience libraries and the [http://www.metadecks.org/software/sweep/ sweep] audio editor. He is heavily involved in the Annodex project and mentored the successful &quot;OggSkeleton support&quot; project in GSoC 2006.<br /> <br /> Jean-Marc Valin is the architect and lead developer of the Speex voice codec. He has been involved in Xiph.Org since 2002. He mentored an audio codec research project in GSoC 2006.<br /> <br /> Arek Korbik is the author of the [http://xiph.org/quicktime/ Xiph QuickTime Components]. He has been a project contributor since 2005.<br /> <br /> ==== What is your plan for dealing with disappearing students? ====<br /> <br /> ''This needs revisiting.''<br /> <br /> ==== What is your plan for dealing with disappearing mentors? ====<br /> <br /> ''This needs revisiting.''<br /> <br /> ==== What steps will you take to encourage students to interact with your project's community before, during and after the program? ====<br /> <br /> Xiph.Org conducts much of its development discussion and community-building on our IRC channels. We'll ask that the students be present there while they're working, where adequate network access makes that possible. We hope to make them feel that they're an important part of our community; that their contributions are really making a difference towards the goals of Xiph. <br /> <br /> We intend to be open to their contributions - whilst we're aware that initially their work may not be of a quality sufficient to go into our core codebase immediately, we'll give them write access to our repository to work on a branch. We'll ask them to be open in discussing and designing their contributions on IRC and our mailing lists. Our application template welcomes them to come and ask us questions when they're trying to write up their application. We hope that some, or even all, of the students will continue to be part of the Xiph community after SoC concludes. For those students who have not previously contributed to open source software, we'll teach them about how important community building is for the ongoing health of such projects.<br /> <br /> ==== What will you do to ensure that your accepted students stick with the project after GSoC concludes? ====<br /> <br /> We hope that the mentoring process and the experiences they have as part of GSoC will make the students interested in remaining part of Xiph, continuing development on the software they've been working on, and perhaps nurturing their patches towards inclusion in an actual release.<br /> <br /> A very important part of GSoC is for us to make them active members of the community, in particular on the irc channels and the mailing lists. Past experience tells that once they have become part of that community, they will stick around for longer.<br /> <br /> We will encourage them not to consider this just &quot;a summer job&quot;, but as being part of a real community - and doing something that is both interesting, and useful to the wider world.</div>

Google lists the following questions in their [http://code.google.com/soc/2008/faqs.html#0.1_org_apply faq]. Our work-in-progress answers are inline.<br /> <br /> ==== Describe your organization. ====<br /> <br /> [http://xiph.org Xiph.Org] is an open source project and non-profit corporation dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the internet and other digital distribution networks. Over the past 8 years we have developed most of the major patent-free audio and video codecs currently in use, including Vorbis, Speex, FLAC and Theora, as well as developing the Ogg streaming format, and the Icecast streaming media server.<br /> <br /> This year we are also coordinating projects for the [http://annodex.org Annodex association] under our umbrella. The [http://annodex.net/ Annodex project] <br /> is developing a set of open specifications and open source software to allow the creation of hyperlinked Webs of audio and video integrated with the text-based view of the current Web. Toward this goal, Annodex has done a great deal of work developing tools, browser plugins and convenience libraries to facilitate adoption of Xiph.Org's lower-level technology. As such the two projects have largely aligned goals, but focus on different levels in the stack.<br /> <br /> ==== Why is your organization applying to participate in GSoC 2008? What do you hope to gain by participating? ====<br /> <br /> We believe that Xiph.Org has a wide-ranging set of projects that are both challenging and educational for the students. Furthermore, they are important/useful goals for the wider technology community, and especially users of open source software.<br /> <br /> We believe that Xiph's mandate to develop multimedia standards and software is an important one, but we--of course--have limited resources. We hope that the results of GSoC will include the direct benefit of new software development, but also help grow the number of active participants in a long-term manner. Most of our core developers started as students, but just as many have moved on since their student days. Attracting and retaining students is essential to the health and sustainability of our project and is an important goal for all of us.<br /> <br /> ==== Did your organization participate in past GSoCs? If so, please summarize your involvement and the successes and challenges of your participation. ====<br /> <br /> Xiph.Org was invited to participate in GSoc in both 2006 and 2007, and informally mentored Annodex-related projects as well.<br /> <br /> In 2006, we were granted funding for 6 slots. One we weren't able to fill because our chosen students picked or were assigned to other projects. <br /> <br /> Two were [http://code.google.com/soc/xiph/about.html successful]. One, a [http://code.google.com/soc/xiph/appinfo.html?csaid=5F9265EEC6FA0611 hardware implementation of a Theora decoder]: this project produced HDL implementation of the major decoder components, to be used with a general purpose CPU, such as the open source LEON sparc implementation.

Two, [http://code.google.com/soc/xiph/appinfo.html?csaid=213E2D30F095565D implementation of OggSkeleton support] in various tools. We have maintained contact with the two successful students since the program finished. One has continued to contribute code outside the GSoC term, continuing related work.<br /> <br /> The remaining three were unsuccessful through lack of necessary skills, health complications, insufficient motivation, or some combination of all of these.<br /> <br /> In 2007, we were given 2 project slots. One was an extension of the hardware decoder effort from last year. The other was helping to do R&amp;D on Xiph's next-generation audio codec, Ghost. Both were marginally successful - the students reached the minimum goals set, but little more, and did not maintain contact with Xiph.org after the program. <br /> <br /> We enjoyed our participation over the last two years. It provided needed external input, energizing our project and improving our connections to the rest of the open source community. We think we've learnt a lot about how to mentor new and upcoming contributors, and how to best screen the applications we do receive.<br /> <br /> ==== If your organization has not previously participated in GSoC, have you applied in the past?

<p>Msmith: </p> <hr /> <div>== Xiph.org Application as a mentoring organization ==<br /> <br /> We need to apply for consideration as a mentoring organization 2008 March 3-12. Google lists the following questions in their [http://code.google.com/soc/2008/faqs.html#0.1_org_apply faq]. Our work-in-progress answers are inline.<br /> <br /> ==== Describe your organization. ====<br /> <br /> [http://xiph.org Xiph.Org] is an open source project and non-profit corporation dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the internet and other digital distribution networks. Over the past 8 years we have developed most of the major patent-free audio and video codecs currently in use, including Vorbis, Speex, FLAC and Theora, as well as developing the Ogg streaming format, and the Icecast streaming media server.<br /> <br /> This year we are also coordinating projects for the [http://annodex.org Annodex association] under our umbrella. The [http://annodex.net/ Annodex project] <br /> is developing a set of open specifications and open source software to allow the creation of hyperlinked Webs of audio and video integrated with the text-based view of the current Web. Toward this goal, Annodex has done a great deal of work developing tools, browser plugins and convenience libraries to facilitate adoption of Xiph.Org's lower-level technology. As such the two projects have largely aligned goals, but focus on different levels in the stack.<br /> <br /> ==== Why is your organization applying to participate in GSoC 2008? What do you hope to gain by participating? ====<br /> <br /> We believe that Xiph.Org has a wide-ranging set of projects that are both challenging and educational for the students. Furthermore, they are important/useful goals for the wider technology community, and especially users of open source software.<br /> <br /> We believe that Xiph's mandate to develop multimedia standards and software is an important one, but we--of course--have limited resources. We hope that the results of GSoC will include the direct benefit of new software development, but also help grow the number of active participants in a long-term manner. Most of our core developers started as students, but just as many have moved on since their student days. Attracting and retaining students is essential to the health and sustainability of our project and is an important goal for all of us.<br /> <br /> ==== Did your organization participate in past GSoCs? If so, please summarize your involvement and the successes and challenges of your participation. ====<br /> <br /> Xiph.Org was invited to participate in GSoc in both 2006 and 2007, and informally mentored annodex-related projects as well.<br /> <br /> In 2006, we were granted funding for 6 slots. One we weren't able to fill because our chosen students picked or were assigned to other projects. <br /> <br /> Two were [http://code.google.com/soc/xiph/about.html successful]. One, a [http://code.google.com/soc/xiph/appinfo.html?csaid=5F9265EEC6FA0611 hardware implementation of a theora decoder]: this project produced HDL implementation of the major decoder components, to be used with a general purpose CPU, such as the open source LEON sparc implementation. Real time playback of SD content was demonstrated using these components in combination with the proprietary Nagios cpu design. Two, [http://code.google.com/soc/xiph/appinfo.html?csaid=213E2D30F095565D implementation of OggSkeleton support] in various tools. We have maintained contact with the two successful students since the program finished. One has continued to contribute code outside the GSoC term, continuing related work.<br /> <br /> The remaining three were unsuccessful through lack of necessary skills, health complications, insufficient motivation, or some combination of all of these.<br /> <br /> In 2007, (... HELP!)<br /> <br /> We enjoyed our participation over the last two years. It provided needed external input, energizing our project and improving our connections to the rest of the open source community. We think we've learnt a lot about how to mentor new and upcoming contributors, and how to best screen the applications we do receive.<br /> <br /> ==== If your organization has not previously participated in GSoC, have you applied in the past? If so, for what year(s)? ====<br /> <br /> We have participated previously.<br /> <br /> ==== Who will your organization administrator be? Please include Google Account information. ====<br /> <br /> Mike Smith has volunteered to be the primary admin this year. Google account mlrsmith@gmail.com.<br /> <br /> ==== What license(s) does your project use? ====<br /> <br /> n general, we use a modified-BSD style license for our libraries, to enable the widest possible uses of our formats and reference implementations.<br /> <br /> Our applications are generally GPL but LGPL or (GPL-compatible) modified BSD is also acceptable.<br /> <br /> ==== What is the URL for your ideas page? ====<br /> <br /> http://wiki.xiph.org/index.php/Summer_of_Code<br /> <br /> ==== What is the main development mailing list or forum for your organization? ====<br /> <br /> We don't have a single central mailing list for all of Xiph.Org. Instead, we have per-project mailing lists; of these the most active is vorbis-dev@xiph.org. A complete listing of our lists is available at:<br /> <br /> http://lists.xiph.org/mailman/listinfo/<br /> <br /> The primary contact of the Annodex projects is [http://lists.annodex.net/ annodex-dev@lists.annodex.net]<br /> <br /> ==== What is the main IRC channel for your organization? ====<br /> <br /> Our main channel is #xiph on irc.freenode.net. We also have project channels: #vorbis, #theora, #icecast and #annodex are the major ones.<br /> <br /> ==== Does your organization have an application template you would like to see students use? If so, please provide it now. ====<br /> <br /> http://wiki.xiph.org/index.php/Summer_of_Code_Applications<br /> <br /> ==== Who will be your backup organization administrator? Please include Google Account information. ====<br /> <br /> Ralph Giles will be the backup admin if no one else volunteers. Google account giles@xiph.org.<br /> <br /> ==== Who will your mentors be? Please include Google Account information. ====<br /> <br /> * '''Mike Smith''': google account mlrsmith@gmail.com<br /> * '''Ralph Giles''': google account giles@xiph.org<br /> * '''Silvia Pfeiffer''': google account silviapfeiffer1@gmail.com<br /> * '''Christopher Montgomery''': google account xiphmont@gmail.com<br /> * '''Timothy Terriberry''': google account tterribe@vt.edu<br /> * '''Jan Gerber''': google account jan.gerber@gmail.com<br /> * '''Conrad Parker''': google account conrad.parker@gmail.com<br /> * '''Jean-Marc Valin''': google account jmvalin@gmail.com<br /> * '''Arek Korbik''': google account arkadini@gmail.com<br /> <br /> ==== What criteria did you use to select these individuals as mentors? Please be as specific as possible. ====<br /> <br /> We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br /> <br /> The majority of the mentors we've selected are core developers on the various Xiph.Org sub-projects that they've volunteered to mentor for. They have been contributing to Xiph.Org for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br /> <br /> Mike Smith has been involved with Xiph.Org and multimedia development since 2000 and remains one of our most involved core members.

This section is for development of our joint application with [http://annodex.net/ Annodex].<br /> <br /> Here are the questions the [http://code.google.com/support/bin/answer.py?answer=60303&amp;topic=10727&amp;ctx=sibling GSoC faq] says we must address:<br /> <br /> ==== Describe your organization ====<br /> <br /> [http://xiph.org Xiph.org] is an open source project and non-profit corporation dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the internet and other digital distribution networks. Over the past 8 years we have hosted development for all the major patent-free audio and video codec development, including the Vorbis, Speex, FLAC and Theora, the Ogg streaming format, and the icecast streaming media server.<br /> <br /> This year we are also coordinating projects for the [http://annodex.org Annodex association] under our umbrella. The [http://annodex.net/ Annodex project] <br /> is developing a set of open specifications and open source software to allow the creation of hyperlinked Webs of audio and video integrated with the text-based view of the current Web. Toward this goal, Annodex has done a great deal of work developing tools, browswer plugins and convenience libraries to facilitate adoption of Xiph.org's lower-level technology. As such the two projects have largely aligned goals, but focus on different levels in the stack.<br /> <br /> ==== Why is your organization applying to participate in GSoC 2007? What do you hope to gain by participating? ====<br /> <br /> We believe that Xiph.Org has a wide-ranging set of projects that are both challenging and educational for the students, and important/useful goals for the wider open source community.<br /> <br /> We believe that Xiph's mandate, to develop multimedia standards and software, is an important one, but we - of course - have limited resources. We hope that the results of GSoC will include both the direct benefits of software being developed, but also help grow the number of active participants in a long-term manner - retaining students and hopefully eventually having some of them become key members is an important goal for us.<br /> <br /> ==== Did your organization participate in GSoC 2005 or 2006? If so, please summarize your involvement and the successes and failures of your student projects. ====<br /> <br /> Xiph.org was invited to participate in GSoc 2006, and informally mentored annodex-related projects as well.<br /> <br /> We were granted funding for 6 slots. One we weren't able to fill because our chosen students picked (or were assigned to) other projects. <br /> <br /> '''Two were [http://code.google.com/soc/xiph/about.html successful]''': One, a [http://code.google.com/soc/xiph/appinfo.html?csaid=5F9265EEC6FA0611 hardware implementation of a theora decoder].

It energized our project and improved our connections to the rest of the open source community. We learned some lessons about mentoring and especially about applicant screening and would appreciate a chance to apply them in a second round.<br /> <br /> ==== If your organization has not previously participated in GSoC, have you applied in the past? If so, for what year(s)? ====<br /> <br /> We did not apply outside of our invitation in 2006.<br /> <br /> ==== Who will your organization administrator be? Please include Google Account information. ====<br /> <br /> Ralph Giles: google account giles@xiph.org<br /> <br /> ==== What license does your project use? ====<br /> <br /> In general, we use a modified-BSD style license for our libraries, to enable the widest possible uses of our formats and reference implementations.<br /> <br /> Our applications are generally GPL but LGPL or (GPL-compatible) modified BSD is also acceptable.<br /> <br /> ==== What is the URL for your ideas page? ====<br /> <br /> This wiki page contains our current suggestions: (updates needed for 2007):<br /> <br /> http://wiki.xiph.org/index.php/Summer_of_Code<br /> <br /> ==== What is the main development mailing list for your organization? ====<br /> <br /> We don't have a single central mailing list for all of Xiph.Org. Instead, we have per-project mailing lists; of these the most active is vorbis-dev@xiph.org. A complete listing of our lists is available at:<br /> <br /> http://lists.xiph.org/mailman/listinfo/<br /> <br /> ==== What is the main IRC channel for your organization? ====<br /> <br /> We use freenode (irc.freenode.net), with a number of channels. #xiph is the main organisation-wide one, but we also have project channels: #vorbis, #theora, #icecast and #annodex are the major ones.<br /> <br /> ==== Does your organization have an application template you would like to see students use?

He has been an active contributor since 2003.

He has been a project contributor since 2005.<br /> <br /> ==== What criteria did you use to select these individuals as mentors? Please be as specific as possible. ====<br /> <br /> We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br /> <br /> The majority of the mentors we've selected are core developers on the various Xiph.Org sub-projects that they've volunteered to mentor for. They have been contributing to Xiph.Org for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br /> <br /> ==== What is your plan for dealing with disappearing students? ====<br /> <br /> Though the details of dealing with students on a day-to-day basis will fall to the individual mentors, we will set some requirements for reporting progress. We expect mentors to be in contact with their students at least several times a week, and ideally daily (during the working week). Back-up mentors will also stay in contact.<br /> <br /> We will require students to send a brief summary of their progress to the relevant sub-project mailing list once a week. This is not intended as an onerous requirement: just a sign that progress is being made. Should a student fail to do this, without having negotiated an exemption from their mentor beforehand, we'll send them a (polite) warning, and ask the mentor to take a closer look at what the student is getting done. <br /> <br /> Should the student then continue to be absent, we'll be forced to take additional action - up to and including requesting that google withhold payment from them. We hope for none of this to be needed, but our experiences last year indicated that in at least some cases it may well be.<br /> <br /> Xiph.Org also holds monthly IRC meetings where we try to get status updates on our various sub-projects, progress, etc. We'll ask that each student attend (unless their timezone makes this prohibitively difficult, in which case we'll ask them for a pre-prepared progress report to give at the meeting).<br /> <br /> ==== What is your plan for dealing with disappearing mentors? ====<br /> <br /> Our project-suggestions page has at least two mentors for every project. Should we decide to select a project not listed on that page, we would not do so without finding both a willing mentor and an available backup.<br /> <br /> In most cases, the mentors are core developers who have been an active part of Xiph.Org for a number of years, so we think that disappearing mentors are relatively unlikely, but this provides the neccesary backup should a mentor be unable to continue for unforseen reasons.<br /> <br /> ==== What steps will you take to encourage students to interact with your project's community before, during and after the program? ====<br /> <br /> Xiph.Org conducts much of its development discussion and community-building on our IRC channels. We'll ask that the students be present there while they're working, where adequate network access makes that possible. We hope to make them feel that they're an important part of our community; that their contributions are really making a difference towards the goals of Xiph. <br /> <br /> We intend to be open to their contributions - whilst we're aware that initially their work may not be of a quality sufficient to go into our core codebase immediately, we'll give them write access to our repository to work on a branch. We'll ask them to be open in discussing and designing their contributions on irc and our mailing lists. Our application template welcomes them to come and ask us questions when they're trying to write up their application. We hope that some, or even all, of the students will continue to be part of the Xiph community after SoC concludes. For those students who have not previously contributed to open source software, we'll teach them about how important community building is for the ongoing health of such projects.<br /> <br /> ==== What will you do to ensure that your accepted students stick with the project after GSoC concludes? ====<br /> <br /> We hope that the mentoring process and the experiences they have as part of GSoC will make the students interested in remaining part of Xiph, continuing development on the software they've been working on, and perhaps nurturing their patches towards inclusion in an actual release.<br /> <br /> We intend to encourage them not just to consider this as &quot;a summer job&quot;, but as being part of a real community - and doing something that's both interesting, and useful to the wider world of open source software.</div>

He helped write major portions of the vorbis-tools suite and the icecast streaming media server. He currently works as a developer at Fluendo.com on the GStreamer multimedia framework, flumotion (a streaming media server), and other multimedia software. <br /> <br /> '''Ralph Giles''': google account giles@xiph.org<br /> <br /> '''Silvia Pfeiffer''': google account silviapfeiffer1@gmail.com<br /> <br /> '''Christopher Montgomery''': google account xiphmont@gmail.com<br /> <br /> '''Timothy Terriberry''': google account tterribe@vt.edu<br /> <br /> '''Jan Gerber''': google account jan.gerber@gmail.com<br /> <br /> '''Conrad Parker''': google account conrad@metadecks.org<br /> <br /> === What criteria did you use to select these individuals as mentors? Please be as specific as possible. ===<br /> <br /> We selected our mentors from the 'core' developers and contributors within Xiph. Mentors were selected based on how well they know the code area they're volunteering to mentor, how long they've been part of Xiph, how well they interact with others (particularly in terms of building community around our projects).<br /> <br /> The majority of the mentors we've selected are core developers on the various Xiph.Org sub-projects that they've volunteered to mentor for. They have been contributing to Xiph.Org for at least several years, and have shown a persistent interest both in the software we develop, and in helping to create a community around it. We have also made sure that each mentor has sufficient time available to adequately mentor their student(s).<br /> <br /> === What is your plan for dealing with disappearing students? ===<br /> <br /> Though the details of dealing with students on a day-to-day basis will fall to the individual mentors, we will set some requirements for reporting progress. We expect mentors to be in contact with their students at least several times a week, and ideally daily (during the working week). Back-up mentors will also stay in contact.<br /> <br /> We will require students to send a brief summary of their progress to the relevant sub-project mailing list once a week. This is not intended as an onerous requirement: just a sign that progress is being made. Should a student fail to do this, without having negotiated an exemption from their mentor beforehand, we'll send them a (polite) warning, and ask the mentor to take a closer look at what the student is getting done. <br /> <br /> Should the student then continue to be absent, we'll be forced to take additional action - up to and including requesting that google withhold payment from them. We hope for none of this to be needed, but our experiences last year indicated that in at least some cases it may well be.<br /> <br /> Xiph.Org also holds monthly IRC meetings where we try to get status updates on our various sub-projects, progress, etc. We'll ask that each student attend (unless their timezone makes this prohibitively difficult, in which case we'll ask them for a pre-prepared progress report to give at the meeting).<br /> <br /> === What is your plan for dealing with disappearing mentors? ===<br /> <br /> Our project-suggestions page has at least two mentors for every project. Should we decide to select a project not listed on that page, we would not do so without finding both a willing mentor and an available backup.<br /> <br /> In most cases, the mentors are core developers who have been an active part of Xiph.Org for a number of years, so we think that disappearing mentors are relatively unlikely, but this provides the neccesary backup should a mentor be unable to continue for unforseen reasons.<br /> <br /> === What steps will you take to encourage students to interact with your project's community before, during and after the program? ===<br /> <br /> Xiph.Org conducts much of its development discussion and community-building on our IRC channels. We'll ask that the students be present there while they're working, where adequate network access makes that possible. We hope to make them feel that they're an important part of our community; that their contributions are really making a difference towards the goals of Xiph. <br /> <br /> We intend to be open to their contributions - whilst we're aware that initially their work may not be of a quality sufficient to go into our core codebase immediately, we'll give them write access to our repository to work on a branch. We'll ask them to be open in discussing and designing their contributions on irc and our mailing lists. Our application template welcomes them to come and ask us questions when they're trying to write up their application. We hope that some, or even all, of the students will continue to be part of the Xiph community after SoC concludes. For those students who have not previously contributed to open source software, we'll teach them about how important community building is for the ongoing health of such projects.<br /> <br /> === What will you do to ensure that your accepted students stick with the project after GSoC concludes? ===</div>

<p>Msmith: </p> <hr /> <div>== Applying for a Google Summer of Code project with Xiph.Org ==<br /> <br /> Prospective students: please fill out a copy of this template for your application, answering each question in plenty of detail. The more information the better - though we might ask you for more details later anyway.<br /> <br /> Our list of suggested projects is at http://wiki.xiph.org/index.php/Summer_of_Code. You're welcome to suggest other projects, though, if you think you have a good idea. Feel free to jump on irc (irc.freenode.net, #xiph) if you'd like to discuss things before submitting a project proposal.<br /> <br /> = Name and Contact details =<br /> <br /> Your name and email address here. <br /> <br /> = Your background = <br /> <br /> You're a student! Tell us about what you're studying, where, and so on. Tell us what your interests are, what (if any) work you've previously done in the field of multimedia, and so on.<br /> <br /> If you've worked on free software before, that's great. Tell us what you've worked on, what you've done for those projects, etc.<br /> <br /> = Project = <br /> <br /> What project would you like to work on? If it's one from our list of suggestions, don't just copy the title from there - tell us a bit about what approach(es) you'd like to take to this project. If it's not from that list, tell us as much as you can about what you want to do.<br /> <br /> = Project outcomes = <br /> <br /> Go into more details here: what do you think you'll be able to get done in the three months available? Name specific goals: features, percentage performance improvements, etc.<br /> <br /> = Schedule = <br /> <br /> Give us a rough outline of how you want to schedule your work over the three months. If you're going to be away for any part of that, let us know now - it's not a problem if you're heading off on holidays for a week or two, but we have to be convinced you're going to put enough time in. When will you start? What milestones do you want within the project? How much time will you be able to put in?<br /> <br /> = Why should we select you? =<br /> <br /> Google's Summer of Code project is enormously popular - unfortunately, we'll have to reject many more proposals than we'll be able to accept. So this is your chance to tell us what makes YOU the best person for us to pick.</div>

<p>Msmith: scum</p> <hr /> <div>== Spam ==<br /> <br /> Hello, it seems there is at least one spammer who injects spam into this wiki on a regular schedule. The list of URLs this spammer appends to articles is quite constant (google bombing?).<br /> <br /> Is it possible to reject any edits containing certain words (in this case: URLs)?<br /> <br /> Maik Merten<br /> <br /> :According to [http://meta.wikimedia.org/wiki/Vandalbot this page], it is possible to ban certain URLs. &quot;A developer can add their site to the list of bad URLs. You can't save a page with a bad URL in it.&quot;<br /> <br /> ::Or, for a first measure, some admin could block the offending ip address(range). Maybe someone also wants to send an abuse record to the corresponding provider, found by a whois query for these addresses.<br /> <br /> === another way to avoid spam ===<br /> <br /> # make the wiki editable only by registered users.<br /> # create a ''Guest'' user<br /> # show the password of the ''Guest'' account on the edit/login page<br /> Result: the autospam robots can't edit the page, all the human can.</div>

<p>Msmith: note that writ is not supported by any applications in response to request for info</p> <hr /> <div>== Introduction ==<br /> <br /> Ogg Writ is a text phrase codec. While it's primary purpose is to embed subtitles or captions in a Theora stream, it's design makes it useful for many other purposes. It could provide lyrics to song encoded in Vorbis, a transcript to a political debate or oral history recording encoded in Speex, or even incorporate a live chat session as part of a continuous video stream.<br /> <br /> One of the unique aspects of Writ is its discontinuous nature, that is, unlike other Ogg codecs the granules for which seperate packets effect may overlap. See the Granules and Muxing section below for how this works.<br /> <br /> == SVN ==<br /> <br /> Current Ogg Writ development is on Xiph CVS as package &quot;writ&quot;. It's being developed to use libogg2, so you'll need both to work on it. The reference encoder and decoder are available as part of the py-ogg2 package which is available on Xiph SVN at http://svn.xiph.org/trunk/py-ogg2/<br /> <br /> == Application Support ==<br /> <br /> Writ is still highly speculative and incomplete. It is not supported by any applications at this time.<br /> <br /> == Format ==<br /> Writ has been designed so that encoders/decoders can support a bare minimum and be fully compatable with future minor versions. Each minor version adds a new feature, some building on others, adding a new header packet and likely a new field to each body packet. <br /> <br /> Decoders should ignore header packets beyond what they were written to support and also ignore extra fields in data packets beyond their current version. This allows new features to be added without requiring that all software, or even most software, to support them. <br /> <br /> Header Packet 0 (BOS, 16 bytes):<br /> 8 0x00 (Packet ID, Header 0)<br /> 32 &quot;writ&quot; (LSB 0x74697277) (Codec Identification)<br /> 8 version (unsigned int, 0 = Alpha)<br /> 8 minor version (unsigned int)<br /> 32 granulerate_numerator (unsigned int)<br /> 32 granulerate_denominator (unsigned int)<br /> <br /> Data Packet (each):<br /> 8 0xFF (Packet ID, Data Packet)<br /> 64 granule_start (signed integer)<br /> 32 granule_duration (unsigned integer)<br /> 8 text_length (unsigned integer)<br /> ** text_string (variable-length UTF-8 string)<br /> <br /> <br /> '''Minor version 1''' adds multiple language support <br /> <br /> Header Packet 1 (Language Definition, 8+ bytes) :<br /> 8 0x01 (Packet ID, SubHeader 1)<br /> 32 &quot;writ&quot; (LSB 0x74697277) (Codec Identification)<br /> 8 num_languages (unsigned int)<br /> [repeated 1+num_languages times] :<br /> 8 language_length (unsigned int)<br /> ** language_string (0+language_length rfc3066)<br /> 8 language_desc_length (unsigned int)<br /> ** language_desc_string (0+language_desc_length UTF-8)<br /> <br /> Data Packet (each):<br /> 8 0xFF (Packet ID, Data Packet)<br /> 64 granule_start (signed integer)<br /> 32 granule_duration (unsigned integer)<br /> [repeated num_languages times] :<br /> 8 text_length (unsigned integer)<br /> ** text_string (variable-length UTF-8 string)<br /> <br /> <br /> '''Minor version 2''' adds text window support<br /> <br /> Header Packet 2 (Window Definition, 10+ bytes) :<br /> 8 0x02 (Packet ID, SubHeader 2)<br /> 32 &quot;writ&quot; (LSB 0x74697277) (Codec Identification)<br /> 16 location_scale_x (unsigned int)<br /> 16 location_scale_y (unsigned int)<br /> 8 num_windows (unsigned int)<br /> [if (window_num &gt; 0) repeated window_num times] :<br /> ** location_x (variable length, see below)<br /> ** location_y (variable length, see below)<br /> ** location_width (variable length, see below)<br /> ** location_height (variable length, see below)<br /> 2 alignment_x (horizontal alignment, see below)<br /> 2 alignment_y (vertical alignment, see below)<br /> <br /> Data Packet (each):<br /> 8 0xFF (Packet ID, Data Packet)<br /> 64 granule_start (signed integer)<br /> 32 granule_duration (unsigned integer)<br /> [repeated num_languages times] :<br /> 8 text_length (unsigned integer)<br /> ** text_string (variable-length UTF-8 string)<br /> [if (window_num &gt; 1)] :<br /> 8 window_id (unsigned integer)<br /> <br /> <br /> === Example Stream ===<br /> Header Packet 0<br /> version 0<br /> minor version 2<br /> granulenum 1<br /> granuledom 1<br /> \x00writ\x00\x02\x01\x00\x00\x00\x01\x00\x00\x00<br /> <br /> Header Packet 1<br /> num_languages 2<br /> Language 0:<br /> language en<br /> language_desc English<br /> Language 1:<br /> language es<br /> language_desc Spanish<br /> \x01writ\x01\x02en\x07English\x02es\x07Spanish<br /> <br /> Header Packet 2<br /> location_scale_x 4000 (12 bits)<br /> location_scale_y 270 ( 9 bits)<br /> num_windows 2<br /> Window 0:<br /> location_x 1<br /> location_y 2<br /> location_width 3<br /> location_height 1<br /> alignment_x 3 (Full)<br /> alignment_y 3 (Full)<br /> Window 1:<br /> location_x 5<br /> location_y 6<br /> location_width 7<br /> location_height 1<br /> alignment_x 3 (Full)<br /> alignment_y 3 (Full)<br /> \x02writ\xa0\x0f\x0e\x01\x02\x01\x20\x60\x00\x02\x7c\x01\x18\x38\x80\x00\x0f<br /> <br /> Phrase Packet:<br /> granule_start 5<br /> granule_duration 10<br /> Language 0: &quot;Hello World!&quot;<br /> Language 1: &quot;Hola, Mundo!&quot;<br /> window_id 0<br /> \xff\x05\x00\x00\x00\x00\x00\x00\x00\x0a\x00\x00\x00\x0cHello World!\x0cHola, Mundo!\x00<br /> <br /> Phrase Packet:<br /> granule_start 12<br /> granule_duration 15<br /> Language 0: &quot;It's a beautiful day to be born.&quot;<br /> Language 1: &quot;Es un día hermoso para que se llevará.&quot;<br /> window_id 1<br /> \xff\x0c\x00\x00\x00\x00\x00\x00\x00\x0f\x00\x00\x00\x20It's a beautiful day to be born.\x26Es un d\xeda hermoso para que se llevar\xe1.\x01<br /> <br /> <br /> === Granules and Muxing ===<br /> <br /> Granulepos in Writ (as well as future discontinuous codecs) will be by start time, not end time, that the data in a given page is tagged for. This greatly simplifies this specification.<br /> <br /> All Writ phrases will be provided at and given the granulepos of their start time, ordered by their start time within the logical bitstream.<br /> <br /> Phrase packets with long durations should be repeated in the logical bitstream at regular intervals to ensure that a player seeking to the middle of their duration will still see them. These packet copies will be identical to their original, including the start and duration fields, the granulepos of the page they reside on will be incremented for each copy to place it forward on the logical bitstream.<br /> <br /> No two phrases can start on the same granule. On decoding, each packet's start granule is checked against already known packets. If a match is found the new packet is ignored. This prevents phrase copies from being interpreted as new phrases.<br /> <br /> === Seeking Example ===<br /> <br /> Here is a timeline (granule numbers at top, read down) of a sample stream:<br /> <br /> &lt;- Granules -&gt;<br /> 0000000000111111111122222222223333333333444444444455555555556666666666<br /> 0123456789012345678901234567890123456789012345678901234567890123456789<br /> ___________ ____________ ____________ ____________ _____________<br /> |_Vorbis____||_Vorbis_____||_Vorbis_____||_Vorbis_____||_Vorbis______|<br /> ____________________ ____________________________________<br /> |_A____________&gt;_____| |_D____________&gt;______________&gt;______|<br /> _________ ___ __________ ___________<br /> |_B_______| |_C_| |_E________| |_F_________|<br /> .<br /> (note: these have been seperated vertically for easy viewing only)<br /> .<br /> Packet Granule Description<br /> V H0 0 Vorbis Header 0x01 (page by itself, BOS)<br /> W H0 0 Writ Header 0 (page by itself, BOS)<br /> V H1 0 Vorbis Header 0x03<br /> V H2 0 Vorbis Header 0x05<br /> W H1 0 Writ Header 1 (Language Defs)<br /> W H2 0 Writ Header 2 (Window Defs)<br /> W A 0 Writ Phrase A<br /> W B 4 Writ Phrase B<br /> V 12 Vorbis 0-12<br /> W A 15 Writ Phrase A<br /> W C 19 Writ Phrase C<br /> W D 23 Writ Phrase D<br /> V 26 Vorbis 13-26<br /> W E 26 Writ Phrase E<br /> W D 38 Writ Phrase D<br /> V 40 Vorbis 27-40<br /> W F 41 Writ Phrase F<br /> W D 53 Writ Phrase D (EOS)<br /> V 54 Vorbis 41-54<br /> V 69 Vorbis 55-69 (EOS) <br /> <br /> <br /> Player begins decoding at beginning of stream. It reads the BOS pages for both codecs, then receives a non-BOS page. At this point it knows that it has two bitstreams to decode and has resolved that one is Writ and the other Vorbis. It'll continue processing the headers for both.<br /> <br /> Next it's going to find two Writ packets (phrases A and B) and toss them into libwrit. Then it'll get to the first Vorbis data page. It now has data from both bitstreams, and it knows (from the granulepos on the Vorbis page) that it has enough data to run until 12. If there were any Writ packets before 12 they would have appeared first.<br /> <br /> At around granule 9 the listener seeks forward to 24. This will cause a rapid seek through the file to find the first page with a granulepos greater than the seek position and begin decoding at that point.<br /> <br /> It'll find a Vorbis packet containing 13-26 (and not use 13-23) and Writ phrase E. Again, having data from both bitstreams it can begin playing. D would normally appear at granule 24 but is not known about yet. The player knows that this is only enough to decode until 26 so, knowing enough to prebuffer, continues reading the file as it plays the media.<br /> <br /> The next packet it finds is Writ phrase D, and passing it to libwrit, is found that the current granulepos is within the duration. It is thus displayed immediatly, as it's prebuffered, without waiting for granulepos 38. It'll keep reading (because the maximum decoded Vorbis is still 26) and find a Vorbis packet with a 40 granulepos.<br /> <br /> As it nears 38 it'll read the file again and find Writ phrase F, which takes it out to 41. Vorbis only goes until 40, so it'll have to keep reading until the next Vorbis packet.<br /> <br /> Next it'll find Writ phrase D, which will be ignored by libwrit because phrase D is already known (matches start granule of earlier D), and the EOS on that page marks this as the last of the Writ stream.<br /> <br /> It'll continue reading for the next Vorbis data and find the packet for granule 54, followed by the Vorbis packet for granule 69. With that it's EOS, EOF, finished.<br /> <br /> This is of course a simplistic example, Writ and Vorbis will rarely have granules which equal the same amount of time. Each bitstream has its own granule -&gt; time mapping which is calculated when muxing concurrent bitstreams within the file. So if there are 44100 Vorbis granules per second and only 4 Writ granules per second, pages would be ordered as W25 V297892 W31 V385932 W39 W41 V463057 etc. The logic used in the above example works after this granule-time mapping is calculated.<br /> <br /> == Past Discussion ==<br /> <br /> === How does this get &quot;encoded&quot; and &quot;merged&quot;? ===<br /> &lt;purple_haese&gt; The muxing rule is pages are arranged in ascending order by the timestamp that is represented by their granulepos.<br /> <br /> === For what reason is the 0x00 and 0xFF byte at the beginning of header and data packet respectively? ===<br /> &lt;xiphmont&gt; If, after a seek, I hand your codec a header packet, what does the codec do?<br /> &lt;xiphmont&gt; It does nothing. If I haven't told it to reset, the header is not data, it must ignore the header.<br /> &lt;xiphmont&gt; this eliminates a huge raft of special cases in Ogg seeking.</div>

<p>Msmith: evil spammers</p> <hr /> <div>== Introduction ==<br /> Ogg Writ is a text phrase codec. While its primary purpose is to embed<br /> subtitles or captions in a Theora stream, its design makes it useful<br /> for many other purposes. It could provide lyrics to song encoded in<br /> Vorbis, a transcript to a political debate encoded in Speex, or even<br /> incorporate a live chat session as part of a continuous video stream.<br /> <br /> One of the unique aspects of Writ is its discontinuous nature, that is,<br /> unlike other Ogg codecs the granules for which seperate packets effect<br /> may overlap. See the Granules and Muxing section<br /> below for how this works.<br /> <br /> <br /> === SVN ===<br /> Current Ogg Writ development is on Xiph SVN as /trunk/writ/. It's<br /> being developed to use libogg2, so you'll need both to work on it.<br /> The reference encoder and decoder are available as part of the py-ogg2<br /> package which is available on Xiph SVN as /trunk/py-ogg2/.<br /> <br /> <br /> &lt;B&gt;This is a (near final) working draft of the spec&lt;/B&gt;&lt;BR&gt;<br /> Writ has been designed so that encoders/decoders can support a bare<br /> minimum and be fully compatable with future subversions. Each subversion<br /> adds a new feature, some building on others, adding a new header packet<br /> and likely a new field to each body packet.<br /> &lt;P&gt;<br /> Decoders should ignore header packets beyond what they were written to<br /> support and also ignore extra fields in data packets beyond their<br /> current version. This allows new features to be added without requiring<br /> that all software, or even most software, to support them.<br /> &lt;P&gt;<br /> We will be conservative about adding future subversions.<br /> <br /> &lt;pre&gt;<br /> Header Packet 0 (BOS, 16 bytes):<br /> 0x00 ( 8 bit Header 0)<br /> &quot;writ&quot;

These packet copies will<br /> be identical to their original, including the start and duration fields,<br /> the granulepos of the page they reside on will be incremented for each<br /> copy to place it forward on the logical bitstream.<br /> <br /> No two phrases can start on the same granule. On decoding, each packets'<br /> start granule is checked against already known packets. If a match is<br /> found the new packet is ignored. This prevents phrase copies from being<br /> interpreted as new phrases.<br /> <br /> == Seeking Example ==<br /> &lt;pre&gt;<br /> <br /> Here is a timeline (granule numbers at top, read down) of a sample stream:<br /> <br /> &lt;- Granules -&gt;<br /> 0000000000111111111122222222223333333333444444444455555555556666666666<br /> 0123456789012345678901234567890123456789012345678901234567890123456789<br /> ___________ ____________ ____________ ____________ _____________<br /> |_Vorbis____||_Vorbis_____||_Vorbis_____||_Vorbis_____||_Vorbis______|<br /> ____________________ ____________________________________<br /> |_A____________&gt;_____| |_D____________&gt;______________&gt;______|<br /> _________ ___ __________ ___________<br /> |_B_______| |_C_| |_E________| |_F_________|<br /> <br /> (note: these have been seperated vertically for easy viewing only)<br /> <br /> Packet Granule Description<br /> V H0 0 Vorbis Header 0x01 (page by itself)<br /> W H0 0 Writ Header 0 (page by itself)<br /> V H1 0 Vorbis Header 0x03<br /> V H2 0 Vorbis Header 0x05<br /> W H1 0 Writ Header 1 (Language Defs)<br /> W H2 0 Writ Header 2 (Window Defs)<br /> W A 0 Writ Phrase A<br /> W B 4 Writ Phrase B<br /> V 12 Vorbis 0-12<br /> W A 15 Writ Phrase A<br /> W C 19 Writ Phrase C<br /> W D 23 Writ Phrase D<br /> V 26 Vorbis 13-26<br /> W E 26 Writ Phrase E<br /> W D 38 Writ Phrase D<br /> V 40 Vorbis 27-40<br /> W F 41 Writ Phrase F<br /> W D 53 Writ Phrase D (EOF)<br /> V 54 Vorbis 41-54<br /> V 69 Vorbis 55-69 (EOF)<br /> <br /> &lt;/pre&gt;<br /> <br /> Player begins decoding at beginning of stream. It reads the BOS pages<br /> for both codecs, then receives a non-BOS page. At this point it knows<br /> that it has two bitstreams to decode and has resolved that one is Writ<br /> and the other Vorbis. It'll continue processing the headers for both.<br /> <br /> Next it's going to find two Writ packets (phrases A and B) and toss them<br /> into libwrit. Then it'll get to the first Vorbis data page. It now has<br /> data from both bitstreams, and it knows (from the granulepos on the<br /> Vorbis page) that it has enough data to run until 12. If there were any<br /> Writ packets before 12 they would have appeared first.<br /> <br /> At around granule 9 the listener seeks forward to 24. This will cause a<br /> rapid seek through the file to find the first page with a granulepos<br /> greater than the seek position and begin decoding at that point.<br /> <br /> It'll find a Vorbis packet containing 13-26 (and not use 13-23) and Writ<br /> phrase E. Again, having data from both bitstreams it can begin playing.<br /> D would normally appear at granule 24 but is not known about yet. The<br /> player knows that this is only enough to decode until 26 so, knowing<br /> enough to prebuffer, continues reading the file as it plays the media.<br /> <br /> The next packet it finds is Writ phrase D, and passing it to libwrit, is<br /> found that the current granulepos is within the duration. It is thus<br /> displayed immediatly, as it's prebuffered, without waiting for<br /> granulepos 38. It'll keep reading (because the maximum decoded Vorbis<br /> is still 26) and find a Vorbis packet with a 40 granulepos.<br /> <br /> As it nears 38 it'll read the file again and find Writ phrase F, which<br /> takes it out to 41. Vorbis only goes until 40, so it'll have to keep<br /> reading until the next Vorbis packet.<br /> <br /> Next it'll find Writ phrase D, which will be ignored by libwrit because<br /> phrase D is already known (matches start granule of earlier D), and the<br /> EOF on that page marks this as the last of the Writ stream.<br /> <br /> It'll continue reading for the next Vorbis data and find the packet<br /> for granule 54, followed by the Vorbis packet for granule 69. With that<br /> it's EOS, EOF, finished.<br /> <br /> This is of course a simplistic example, Writ and Vorbis will rarely have<br /> granules which equal the same amount of time. Each bitstream has its'<br /> own granule -&gt; time mapping which is calculated when muxing concurrent<br /> bitstreams within the file. So if there are 44100 Vorbis granules<br /> per second and only 4 Writ granules per second, pages would be ordered<br /> as W25 V297892 W31 V385932 W39 W41 V463057 etc. The logic used in the<br /> above example works after this granule-time mapping is calculated.<br /> <br /> <br /> == Ongoing Discussion ==<br /> <br /> * How does this get &quot;encoded&quot; and &quot;merged&quot;?<br /> ** &amp;lt;purple_haese&amp;gt; The muxing rule is pages are arranged in ascending order by the timestamp that is represented by their granulepos.<br /> <br /> * For what reason is the 0x00 and 0xFF byte at the beginning of header and data packet respectively?<br /> ** &amp;lt;xiphmont&amp;gt; If, after a seek, I hand your codec a header packet, what does the codec do?<br /> ** &amp;lt;xiphmont&amp;gt; It does *nothing*. If I haven't told it to reset, the header is not data, *it must ignore the header*.<br /> ** &amp;lt;xiphmont&amp;gt; this eliminates a huge raft of special cases in Ogg seeking.<br /> <br /> <br /> <br /> == &quot;The Old Way&quot; ==<br /> &lt;B&gt;The section below is for historical purposes only!&lt;/B&gt;<br /> &lt;pre&gt;<br /> - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -<br /> 2003/08/17<br /> In a lengthy discussion with Monty and Derf the decidion to change the<br /> behavior of discontinuous bitstreams in Ogg, or rather, extend the<br /> current Ogg specification to handle discontinuous codecs, was made.<br /> - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -<br /> &lt;/pre&gt;<br /> <br /> The Ogg granulepos of each page is equal to the expiration of the text,<br /> packets are ordered by expiration time and may overlap. So, at or before<br /> text A is to be displayed, the following sequence is included:<br /> <br /> &lt;pre&gt;<br /> Physical Text Text Text<br /> Location Packet Start Expire (text expire = page granulepos)<br /> ---------------------------------------<br /> 00 B 04 14<br /> 00 D 19 23<br /> 00 C 09 24<br /> 00 F 27 34<br /> 00 E 26 37<br /> 00 G 35 47<br /> 00 H 42 54<br /> 00 A 00 59<br /> 51 I 51 66<br /> &lt;/pre&gt;<br /> So B, D, C, F, E, G, and H are all defined before A, building a FIFO (first<br /> in first out) buffer in the player. Encoders should limit the extend of this<br /> behavior to reduce nessesary buffer size on the player side by prematurly<br /> expiring captions and recreating them periodically.<br /> <br /> The screen should not be updated with the new captions until they've all<br /> been processed to prevent &quot;flicker&quot;. New caption data to the same position<br /> will scroll the previous data upwards with no line breaks seperating them<br /> (unless present in text).</div>

<p>Msmith: sigh. spam.</p> <hr /> <div>==Motivation==<br /> <br /> All the Xiph.org codecs have some internal mechanism for including metadata about the current stream.<br /> Generally, this is one of the codec headers, and in the words of the [http://www.xiph.org/ogg/vorbis/doc/v-comment.html vorbis spec], <br /> &quot;It is meant for short, text comments...much like someone jotting a quick note on the bottom of a CDR.&quot;<br /> <br /> This works well enough for most things, and can be overloaded/abused (depending on your point of view)<br /> for most other things. But there are three major requirements that point to the design of an external <br /> metadata format; one that can be interleaved with the other streams in a container.<br /> <br /> * ''Machinability'' There are a number of items of metadata that a player will want to parse and take action on. While there are usually 'convention' schemes for doing this with the embedded comment headers, this is much easier if there is a separate metadata stream designed for such use, instead of having to do best-effort parsing of natural language comments. For example, a video file with multiple audio tracks can specify the language of each one; a player than can parse these reliably can match them against a language preference list configured by the user to automatically select and begin playback of the best option.<br /> <br /> * ''Kitchen Sink'' There are a minority of people who care passionately about having every detail about a track available. In the sense of conserving such information, and providing an equivalent to liner notes for online distribution, this is a goal worth supporting. However, the simple unstructured key-value pairs offered by the inline metadata are unwieldy for this level of detail. How do you tell the 2nd unit Assistant Director from the USA unit Assistant Director? How do you indicate which artist played tenor sax in the solo?<br /> <br /> * ''Addressability'' The internal comment metadata headers are by necessity attached to a single content stream. This is useful for some appication, but a limitation in others. In a multiplexed stream, which set of comments refers to the collection as a whole? (By convention, in Ogg, it's the first logical bitstream occuring, but we can do better.) A separate metadata stream type must address this issue of collective metadata while still allowing description of individual streams. It should also allow temporal addressability, so that changes can be described. Because the in-stream comment metadata are part of the codec headers, it cannot change over the course of the stream, and allowing additional comment packets elsewhere in the stream presents seeking challenges. In the Ogg container this can be resolved by inserting a chain boundary, but this is a poor option for very-low-bitrate streams and unreliable transports such as RTP.<br /> <br /> ==Proposed Solutions==<br /> <br /> RDF + dublin core<br /> <br /> XML-encoding (generic rdf or CMML?)</div>
