That's what I thought one of the objections against H.264 in HTML5 was.) > So, I'd expect at least as much from HTML5. If people think that HTML5 should list a set of technologies that must be implemented by implementations of HTML5, I don't mind adding such a list. Coming up with the list seems like a can of worms. Would anyone like to take an action item to discuss with the relevant implementors of each relevant conformance class what the requirements should be, and report back to the group? If there is are prepared lists for the various relevant conformance classes that the relevant implementors agree on, I'd be happy to add it to the spec. (Given my experience trying to get browser vendors to agree on a video codec and a font format, I don't really want to try my luck with another set of formats myself.) -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
