However, Youtube only wants to encode the video into H.264. Safari and Chrome already (or will) implement H.264 codecs. That leaves 3 choices: 1) Don't implement H.264, wait until Youtube encodes the videos to OGG format. 2) Implement H.264 silently, but don't push it. (As in don't release a Firefox with H.264 support.) Wait for Youtube to encode videos to OGG. (If not, implement.) 3) Implement H.264 immediately. Don't wait for Youtube to change. I would prefer option 2, since it lets Firefox keep up, but not let the open video part down. ** So where do we get the codec from? FFMPEG. FFMPEG is a project widely known, and is used in many applications for video decoding (and encoding). There is one problem though - H.264 is patented (one reason I would wait and see for Youtube). FFMPEG describes the legal issues here: http://www.ffmpeg.org/legal.html Strangely enough, Google Chrome will use FFMPEG in their browser for video decoding. I would wait and see, since Google/Youtube may adapt Theora as a format. Apple's Safari implements their own Quicktime library, which they purchased the software rights to use the MPEG and H.264 libraries. You can talk to the FFMPEG developers about their library and the legal issues that surround it, and they might help you. That's all for codecs. ====== VIDEO OUTPUT/SOUND OUTPUT The current method of displaying video is not efficient. For some computers, it may work, but others will have choppy video. The solution is accelerated video output. Accelerated video output is where the video is sent to the video card directly, instead of going through the normal display method. For Linux, there are quite a few. Here are the commonly used ones: - XVideo (default) - GL (OpenGL 1) - GL2 (OpenGL 2) - X11 (standard, nearly no acceleration) For Windows: - DirectX (obviously) - DirectX 3D - OpenGL - GDI - Video Card Memory For Mac OS X: - CoreVideo - Quartz These options SHOULD be placed in the Options dialog, in the Advanced section. Since each computer has a different video configuration, the option should be changeable. So who will implement it? You can ask MPlayer and VLC for help. If you're lucky, they may code the video output stuff for you. They probably (at least) will help you develop the video outputs. ** For the video codecs, I would prefer Theora. There's no patenting issues with it. Theora, by all means, is not as good as H.264. However, if the Theora codec developers get serious and improve the codec to the point it meets or exceeds H.264's quality and features, there will be no reason to not include it in the HTML5 specification. If Theora can be improved a lot, and (maybe) redesigned, it will happen. XVid is also an option.... but is based from MPEG4 specs, and is subject to patents.

Closing this bugs as invalid, as it touches many other bugs together. - implementing H264 : that belongs to the various blogs, websites, newsgroups, etc ... This is a location for filing bugs, not for a discussion. And yes, everybody already knows about all these options. - the different backend implementations are bugs 422540 for GStreamer, bug 435298 for QuickTime, bug 435339 for DirectShow
