What I'm asking is for the vendors to come to a consensus (which is why I said vendors should try to "come to some diplomatic decision") - be selfless rather than selfish. We can mandate Theora or H.264 and not everyone will implement the SHOULD/MUST (which is self-defeating). We can give the vendors a chance to come to an amicable, mutually beneficial decision on their own (which I hope is possible due to each browser making attempts to be interoperable as far as rendering is concerned, but may not be in reality). Or we can give up trying to find a baseline (de facto or mandated) and see what the market dictates (aka give up). Right now, all we're doing is arguing the same two or three points about Theora vs MPEG4 (royalty, submarine patents, amount of distribution, and the like). The debate has been going on in the WHATWG for weeks. WHATWG has no consensus. Most points made pro/con each format are reasonable. So, arguing isn't getting closer to a solution. It's only proving that Theora and MPEG4 are both unacceptable solutions for one or more vendor, and thus would be self-defeating as a baseline. So, I'm aware Microsoft and Apple both have their pet codecs. What I'm asking is for vendors to put aside their self-interest and look at the people who develop for their browser and the people that use their browser (the customers and developers), then do what is best for the Web instead of what is best / easiest for their particular company. <video> shouldn't be a strategic battle to "win" for a pet codec. This isn't about getting in on HD-DVD licensing. This is about a humanitarian effort. Frankly, I don't want there to be a mandated codec. I want the vendors to work it out. I would really love for <video> to be like <img> where I have a few ubiquitous choices (PNG, JPG, GIF) and use which is best for the particular situation (e.g. photos vs icons). If the codec ends up being something like M-JPEG, so be it. At least we have something. If the author of the content wants to export 4 different versions (e.g. WMV, H264, Theora, and DIRAC) to get better quality / bitrates for each browser, let them do that. If the author wants to create one file, even though it isn't the most optimal format, at least they will be able to do that. We're talking about a baseline. At this point, I don't think we can reasonably expect the baseline to be the optimal codec. It is a lowest common denominator between all the browsers that we need. Or can we not look other places than the latest-and-greatest? -- Robert <http://robertdot.org>
