Summer of Code 2009
Students please use the template at Summer of Code Applications when applying for a GSoC position.
Mentors please visit Summer of Code Mentoring and help us prepare our application as a mentoring organization.
- OpenMAX IL components for Ogg codecs
- Get skeleton patches upstream so players stop choking on it.
- Portable listening application for codec MOS/MUSHRA comparisons (Win32, MacOS, Linux; FF3.1 web application?).
- Conference bridge using CELT.
- Reference SIP client for CELT.
- Proof of concept liboggplay-based media patch for Google's Chrome browser.
- Metavid improvements
- Firefox extension to record locally and stream to icecast.
- Firefox extension to support RTP for conferencing.
- also consider applying under Mozilla SOC org.
- mod_duration apache module to generate X-Content-Duration headers for Ogg files. (We should get people to use oggz_chop instead ... oggz_chop provides this functionality and more, is already relatively lightweight.) Perhaps this project could be more focused on packaging oggz_chop for other web servers like lightpd and maybe a fastCGI version and or maybe push for an mod_ogg to be adopted upstream in apache to improve distribution.
Detailed Project Descriptions
These ideas were suggested by various members of the developer community as projects that would be beneficial and which we feel we can mentor. Students should feel free to select one of these, develop a variation, or propose their own ideas. Here, ideally.
Proof of Concept liboggplay (html5 video) support in Chromium Browser
This project would focus on integrating support for liboggplay into chrome. This project would only need to be a proof of concept with the end result being some frames decoded in the browser. We have some direct contacts with people on the Chromium project in Google, but would expect the student mostly to work through the Xiph on Chromium online communities.
- Improve transcript import / export system:
- Wiki to SRT
- SRT to Wiki
- CMML to Wiki
- Extend oggz_chop or other tool for exporting transcript encapsulated in the ogg file.
The main focus of the project is around enabling video accessibility for Ogg in Firefox.
Captions, subtitles and other categories of time-aligned text are starting to become relevant to HTML5. In Ogg, we currently encapsulate such data in OggKate and can use SRT or Kate as input formats. Display of OggKate is currently supported in VLC and there are patches for various other media players. We now want to enable Web browsers to also deal with these time-aligned text tracks in those Web Browsers that support the HTML5 video tag.
The project is adaptable to the qualifications of the student - it may consist in simply implementing a tool-chain for handling srt through OggKate, or it may go much further and include richer forms or time-aligned text such as audio annotations, Karaoke, ticker text, clickable text etc.
OpenMAX IL components for Ogg codecs
OpenMAX is a set of low-level C APIs for media codecs. It is used by many mobile devices, in platforms like Maemo and Android. As we'd like to encourage the use of free codecs on mobile and embedded devices, we want to develop a set of components using our codec libraries.
