Very cool. Out of curiosity, why is the H.265 size slightly more than the H.264 size? How does the compute complexity for encoding and decoding compare with those two codecs?
I got these results by using Vertigo's bitrate as the target, and squeezing the other ones until they got as close as possible to that. H265 is in general better than H264, but when you put the thumbscrews on it seems to get itself into a bit of trouble.
Wrt encoding/decoding complexity this is the major bottleneck, because you have the GPU competing with custom ASICs. I have a version of the codec that works in combination with H265, but still gets largish bandwidth gains, so if all you wanted was an insane hi-res and hi-bitrate transmissions that might be the way to go near-term.
