Ok before delving into the subject, Tom can you put it on ideas.welcomebackstage.com. Its very much the right place to post this type of thing.
I think its significantly different to this, http://ideas.welcomebackstage.com/ideatorrent/idea/6/ It also helps to have something more structured when presentation ideas to others. So support for HTML5's video tag generally sounds good to me. Yes it will upset those with IE browsers but I'm sure someone will come up with some JavaScript/DOM hack which will replace the Video tag with object in the near future. Ogg Theora support in the BBC? Well (cough!) http://welcomebackstage.com/2009/06/rdtv-episode-2/ Will we see it elsewhere like iplayer? I don't know but I would say unlikely for now. In the same way we didn't support Ogg streaming outside of research/dev project. I expect Mpeg4 h.264 will be dominate for a while to come. I personally think if the Xiph foundation can sort out the metadata problem, they will have something very interesting indeed.

I realise there are rights issues with some programmes and that rights holders might have problems with non-DRM solutions, but presumably there are some programmes which the BBC have full rights to. Supporting the <video> tag raises the question of which codec to use, which is difficult to answer because there is no codec that every vaguely popular browser (IE, Firefox, Safari, Opera, Chrome) supports or plans to support in the near future. IE has been silent so far (though there are DirectShow filters for Ogg Theora/Vorbis.[0]). Firefox 3.5 will support Ogg Theora/Vorbis (and cannot support H.264/AAC because of patent issues).[1] Safari will support H.264/AAC (Ogg Theora/Vorbis plugins for Quicktime exist[2]).[3] Opera will support Ogg Theora/Vorbis (I don't know if they plan to purchase licenses for its users.)[4] Chrome will support Ogg Theora/Vorbis and H.264/AAC.[5] I think users of alternative browsers (Firefox, Opera, Chrome), rather than non-alternative browsers would most appreciate <video> to Flash. Also, H.264/AAC cannot be supported in browsers without huge financial backing (because of patent issues), where as Ogg Theora/Vorbis is believed to be patent-free. As such, to benefit most people, I think using Ogg Theora/Vorbis would be the best choice. Regards, Tom Fitzhenry PS. I don't know if this is the right place to post this. I couldn't find a better place though. 0. http://www.xiph.org/dshow/ 1. https://developer.mozilla.org/En/Using_audio_and_video_in_Firefox 2. http://xiph.org/quicktime/ 3. http://webkit.org/blog/140/html5-media-support/ 4. http://labs.opera.com/news/2008/11/25/ 5. http://news.cnet.com/8301-17939_109-10250958-2.html - Sent via the backstage.bbc.co.uk discussion group.
