suppose you're after this info?

Not exactly. Thanks to [vdpau] Probe hw capabilities (experimental), Avidemux correctly refuses to try to decode a h265 video via VDPAU on my hardware:

  [vdpauGetFormat] 09:14:34-620  HEVC:Not supported by HW

Now you should load an 8 bit h265 video and test if Avidemux tries to decode it via VDPAU in hardware.

Without.

Excellent, thanks. Decoding 8 bit h265 via VDPAU works 

The last remaining wish would be support for VDP_DECODER_PROFILE_HEVC_MAIN_10 when supported both by drivers and hardware.

This is not really related to the topic (support for hw-accelerated decoding of HEVC via VDPAU), the MpegTS demuxer has difficulties to analyse this transport stream (this is not a mp4 file). FFmpeg complains about invalid timestamps in the video stream, but mpv manages to play the sample nevertheless (like a slide show due to slow CPU, of course).

Avidemux succeeds loading another Ultra-HD HEVC demo: http://demo-uhd3d.com/fiche.php?cat=uhd&id=45, but crashes with a floating point exception (division by zero in avidemux_core/ADM_coreUtils/src/ADM_infoExtractorH265.cpp:224) loading a real-life DVB-T2 sample ("Das Erste HD" from http://forum.kodi.tv/showthread.php?tid=228769&pid=2333904#pid2333904).

The HEVC/TS parser is incomplete
Additionnaly, the decoder in ffmpeg is not as robust as usual

[eumagga0x2a]

and ffmpeg

This boils down to the question: does 3.0.6 support hevc 10 bit decoding via VDPAU or not?

Thank you very much for the hard work you put into h265 TS demuxing and hw decoding support! With terrestrial TV broadcasting in Germany switching to h265 by the end of March, this work is highly appreciated.

Probably not:

DXVA2-accelerated HEVC Main10 decoding

10-bit depth support in native utvideo decoder

CUDA CUVID H264/HEVC decoder

source: June 27th, 2016, FFmpeg 3.1 "Laplace"

CUVID, which is also called nvdec by Nvidia now, can be used for decoding on Windows and Linux. In combination with nvenc it offers full hardware transcoding.

The full set of codecs being available only on Pascal hardware, which adds VP9 and 10 bit support.

Jan, I just saw

Code Select Expand

static int vdpau_hevc_init(AVCodecContext *avctx)
{
    VdpDecoderProfile profile;
    uint32_t level = avctx->level;

    switch (avctx->profile) {
    case FF_PROFILE_HEVC_MAIN:
        profile = VDP_DECODER_PROFILE_HEVC_MAIN;
        break;
    case FF_PROFILE_HEVC_MAIN_10:
        profile = VDP_DECODER_PROFILE_HEVC_MAIN_10;
        break;
    case FF_PROFILE_HEVC_MAIN_STILL_PICTURE:
        profile = VDP_DECODER_PROFILE_HEVC_MAIN_STILL;
        break;
    default:
        return AVERROR(ENOTSUP);
    }

    return ff_vdpau_common_init(avctx, profile, level);
}

in buildCore/ffmpeg/source/libavcodec/vdpau_hevc.c:403 with the bundled ffmpeg-3.0.6, which I interpreted as an indication that given driver and hardware support the ffmpeg in Avidemux would be capable of using VDPAU to decode 10 bit HEVC videos. CUDA CUVID decoding added in 3.2 is another matter alltogether IMVHO.
