Currently, VDPAU does not seem to support HEVC Main10 at all even where the hardware should support it. (For example,
vdpauinfo returns “— not supported —” on HEVC_MAIN_10 on a GTX 960)
From what I understand, HEVC Main10 is supported via other hardware decoding APIs (e.g. d3d11va) on suitable hardware. Since Main10 seems to be the most common profile from the HEVC test clips I’ve seen, coupled with the fact that main10 is the only profile my CPU is too slow to decode in realtime, this would be a pretty neat feature to have.
