But were that the case, we could have sticked with an older codec, one that didn't have to carry the burden of royalty fees: a choice that several people have often discarded exactly because it wasn't good enough. I could not agree more. > > That's also why I, as it is probably redundant to restate, actually support Harald's view. My concern is that, with H.264, MTI will not mean *a* codec in a negotiatiated session, which is what we all agree RTCWEB still is, or should be. It will be *the* codec, because several implementations, including two currently missing browsers (whenever they'll start to care), will *only* provide H.264, thus forcing everyone to comply with it. Who's going to do anything else, when you know the only way to reach all browsers is *the* codec? And for a lot of people, including me, there's currently (or actually, will be) only one way to do so, which is a plugin (in RTCWEB, ironic) that may or may not be available two months after we start using it. +1 for VP8 as MTI.
