I can understand the appeal, however its just not that feasible on low powered devices(Yet). Most mobiles (most things videos infact) have some silicon dedicated to h26x decoding. Using that silicon is a massive order more efficient (both power and CPU/GPU) Its also more reliable.
The other thing to note is that if ars is correct and that it only uses I-frames only in some cases, its not going to be bandwidth efficient. That's one compromise you can't really make in mobile land. Its also going to require two separate streams (one for each class)
One last thing, I've not actually seen any output "in the flesh" as it were. VP8 was supposed to be wonderful, but in fact its almost a clone of h264, just with marginally worse performance.
(another thing, its actually really hard to make an HD player from scratch. You wouldn't think it but putting frame on screen in a timely and smooth manor is really not trivial.)
- smith7018 14y agoWould you mind going a little more in depth about VP8? Last I heard it was supposedly amazing but that was awhile ago.
- w0utert 14y agoWhat more is there to say about it? It's fundamentally almost exactly the same as H264, minus a few features that would make it too vulnerable to patent litigation, plus a few minor additions that are meant to patch up the efficiency lost by excluding some of H264's features. For web video VP8 performs about the same as H264, for high-bitrate/high quality (think Blu-Ray/Full HD) it performs decidedly worse because it doesn't have most (any?) of the advanced features in H264 main/extended/high profiles. The one big downside is lack of widespread hardware codec support. There really isn't anything 'amazing' about VP8, except that some people think it fixes something about video coding because it is 'more free' than H264, which IMO is vastly overstated. In real life, for 99.9% of people (including those offering commercial video products), the difference is practically philosophical.
