All it has lead me to believe is that X codec is not implementable because of the great risk, where X is Theora or MPEG4 or whatever. The only argument against fear of submarine patents in MPEG4 is: 1. X can make money off of Y. 2. X is not making money off of Y. 3. Therefore, there is no Y. In other words, "There is a pretty good amount of money to be had now from MPEG patent suits, but no one is suing. So, there must not be any patents." Ultimately, there is no assurance in any codec that there are no submarine patents. There might be less perceived risk with one codec than another, but there is nothing is assured (it's all relative perception). Implementing MPEG4 could be just as dangerous as Theora. There is no solution to this argument other than "could", "might", and "maybe." We can argue it forever and we'll get nowhere. I feel similarly about the other points of contention. What I was suggesting was not about settling differences. It was about picking some other baseline codec that has a reasonable chance at being implemented by more than just one browser. If Mac OS X and Windows both play MPEG-1 natively, then obviously both companies are capable of using that as a baseline where H.264 and WMV share no common support (at least according to what I think were your sentiments in an earlier post concerning H.264, though I know Microsoft suggests a 3rd Party plugin to QuickTime to play Windows Media content on Macs). I don't want Apple and Microsoft to hold hands and ride the see-saw together. I just want them to agree on a mutual common baseline codec that they both already support. One that can be watched natively in both OS X and Windows. After the baseline is established, they can support any and all codecs they want. First, though, we need one de facto baseline codec or <video> will not be useful. It doesn't have to be perfect, it just has to be common. I think these discussions are a waste of time and should be handled outside the HTML WG. It'd be great to see the vendors take the initiative to decide this amongst themselves in an incubator group, as Dan suggested. So, I want to put my support behind the suggestion as well. Implementors of the <video> element ought to be involved in this group, should it form. -- Robert <http://robertdot.org>
