Can you confirm h265 (HW Accel) development:
- currently is libva based?
- libvdpau is to follow?
reason to ask: current playback is very slow with 4K h265 within avidemux playback. Looks like slow motion.
I dont have a h265 enabled nvidia card, so i can't test it
OK, hope you planned one in (nearby) future.
you could try, it's not that difficult
You need to change both in avidemux_core and in avidemux/qt5/hwCodec
basically adding a case H265 right below H264
Should be mostly copy/paste
I really wish it were. Simply applying something like

(I haven't found any locations in core which might be relevant, there is some dead code in avidemux_core/ADM_coreVideoCodec/src/ADM_codecSearch.cpp in ADM_coreCodecGetDecoder and that's it) makes Avidemux blindly try to decode h265 via VDPAU and subsequently crash (my Kepler NVIDIA graphics card doesn't have a HEVC decoder either and I am utterly reluctant to switch to the current generation due to worse or completely missing support in the nouveau driver).
The capabilities check might be missing
(like it is done in libva)
It might work with libva wrapper on top of vdpau
(i.e. select libva and deselect vdpau)

10 bit HEVC support seems to be slowly coming to VDPAU users on NVIDIA hardware: https://devtalk.nvidia.com/default/topic/940228/vdpau-expose-hevc-main10-support-where-available-on-die/ (https://devtalk.nvidia.com/default/topic/940228/vdpau-expose-hevc-main10-support-where-available-on-die/). This means, simply replacing

in the patch with

won't make it work for you now (if the reason was a 10 bit video and not a mistake in the code).

Card supports:
As suspected, the stream is 10 bit which is not supported by the NVIDIA binary driver at least (some support might have been added in 370.xx and later) and probably by the hardware as well.
+ffmpeg must support it
I assume the bundled ffmpeg supports it (I got the string from grepping the buildCore/ffmpeg directory, it is used in vdpau_hevc_init in libavcodec/vdpau_hevc.c:413).
The devtalk discussion suggests a recent AMD card might be a better platform to work on VDPAU support.
I've commited a quick patch to add hw probe
Not sure how well it works

Not exactly. Thanks to [vdpau] Probe hw capabilities (experimental) (https://github.com/mean00/avidemux2/commit/868f24f0e70e6b8a559c467407af145eb23eb1bc), Avidemux correctly refuses to try to decode a h265 video via VDPAU on my hardware:

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 (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 (http://forum.kodi.tv/showthread.php?tid=228769&pid=2333904#pid2333904)).

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:

Jan, I just saw
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.
I could not find out, if this is still an issue:
QuoteSetting profiles
Currently, ffmpeg ââ,¬â€¹does not support setting profiles (main, high, ...) via the profile:v option, as libx264 does. However, the profile options can be set manually, as shown ââ,¬â€¹in this Super User post.
source: wiki:Encode/H.265 (https://trac.ffmpeg.org/wiki/Encode/H.265)
10-bit would this also require 10-bit build: x265 libx265 libx265-dev?
Apparently stock 16.04 is 8-bit build.

libx265 (this is an encoder) is completely unrelated to the topic. HEVC 10-bit decoding is not supported by your graphics card in the first place.

You are right, my bad. GTX 960 is feature set F, I've confused it with GTX 980 which is only feature set E.
not on h265, but 10-bit:
QuoteNVIDIA Geforce graphics cards have offered 10-bit per color out to a full screen Direct X surface since the Geforce 200 series GPUs. Due to the way most applications use traditional Windows API functions to create the application UI and viewport display, this method is not used for professional applications such as Adobe Premiere Pro and Adobe Photoshop. These programs use OpenGL 10-bit per color buffers which require an NVIDIA Quadro GPU with DisplayPort connector. A small number of monitors support 10-bit per color with Quadro graphics cards over DVI.
