I have my doubts about H.265 being playable without dedicated hardware decoding, i.e. a chip designed for it. A software update won't do.
Try the following samples. You'll have to download the Elecard Player Alpha as well to play them:
Note that if you have a 4Ghz i7, CPU usage may be 50%, or more. That's a bunch, and none of the samples have a resolution higher than 1080p.
Now, of course there's plenty of room for optimization. Not just for decoding, but for encoding as well. Early builds were in the range of 40x to 60x times slower than H.264. Last I looked at the H.265 discussion at Doom9, 10x was possible. The point being, there's a lot of computational overhead.
Remember the history of H.264, which has been around for what? Ten years? For the first three, it was no great shakes. I say a little patience is in order.
Anyway, my subjective impression is that H.265 is definitely better visually than H.264. It has almost no temporal artifacting, although at the cost of less detail in backgrounds. H.264 (using the x264 encoder) is the opposite, giving more detail at the cost of large distortions. Look carefully sometime at a Blu-ray with leaves moving in the wind. Or moving water. You'll see flickering in the former, shimmering in the latter.
I suppose many of you have seen the following, but here goes anyway. The proposed extensions to HEVC are interesting:
" Companies including ATEME, Broadcom, Cyberlink, Ericsson, Fraunhofer HHI, Mitsubishi, NHK, NTT DOCOMO and Qualcomm have already showcased implementations of HEVC. The new standard includes a ‘Main’ profile that supports 8-bit 4:2:0 video, a ‘Main 10’ profile with 10-bit support, and a ‘Main Still Picture’ profile for still image coding that employs the same coding tools as a video ‘intra’ picture."
"The ITU/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) (formerly JVT) will continue work on a range of extensions to HEVC, including support for 12-bit video as well as 4:2:2 and 4:4:4 chroma formats. Another important element of this work will be the progression of HEVC towards scalable video coding. The three bodies will also work within the Joint Collaborative Team on 3D-Video (JCT-3V) on the extension of HEVC towards stereoscopic and 3D video coding."
