This is our ideas page for Google Summer of Code 2009 projects with Xiph.org and Annodex. The two projects participate jointly this year under Xiph's name.

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.

General Ideas

  • Kate to HTML & CSS overlay library in javascript.
  • Proof of concept liboggplay-based media patch for Google's Chrome browser.
  • mod_duration apache module to generate X-Content-Duration headers for Ogg files.
  • 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.
  • Firefox extension to record locally and stream to icecast.
  • Firefox extension to support RTP for conferencing.

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.

Javascript Library for Subtitles, Captions and other time-aligned text

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 is a patch to mplayer. However, there is no display of OggKate in Firefox 3.1 using HTML5. This can be fixed through the creation of a javascript library that can deal with Kate output and convert it to HTML and CSS. Such a library exists for SRT, but will be extended to Kate in this project.
