It is again an issue with an older libva version in Ubuntu 14.04.5. VAProfileVP9Profile3 is missing there in the list of available profiles in va.h from libva-dev. The commit [libva] Use our new cflags might have exposed the issue.

I wonder if the typo at line 7 of cmake/cmake_compile_check/libva_vp9dec.cpp from the commit [libva] Better detection of system libva (h265, vp9,...) might be related.

You could try the attached patch, even if it doesn't fix the build issue, it won't do any harm.

If yours finds VP9, the detection is wrong.

[mean]

Should work now
be sure to delete the core build tree, some internal vars used are cached

[eumagga0x2a]

libva on Ubuntu 14.04.5 doesn't support HEVC either, so even if the VP9 check really only checked for HEVC (which I gloriously missed looking at the patch ), the result should have been negative, shouldn't it? Anyway, Jan will find it out soon.

Great, the build succeeded, but what did cmake report about libva support?

[Jan Gruuthuse]

there plenty of references for cmake about libva, don't know what your looking for.
Here the logbuildCore for this build:

I meant the output you see in the terminal while building, not logbuildCore. But in this case even logbuildCore is helpful because it indicates in

at line 1493 that cmake detects HEVC as supported (-DLIBVA_HEVC_DEC) despite it being unavailable on 14.04.5. Just for some reason the build still succeeds, but the detection seems to be incorrect.

[Jan Gruuthuse]

perhaps while HEVC is hardware supported here (GTX 960) over vdpau API (VDPAU backend for VA-API - 0.7.3)?
Vainfo is not reporting HEVC:

vdpau only gives decoder info? perhaps nvenc?

No, features supported via VDPAU are not related. CMake tries to compile libva_hevcdec.cpp from the cmake/cmake_compile_check folder. If it succeeds, the feature is supported. If it fails to compile, it is not. Copy this file e.g. to /tmp/, go the /tmp and run

gcc libva_hevcdec.cpp -o hevc-test

If you get a binary hevc-test and no error instead, the detection of HEVC support is not at fault.

You've forgotten to change directory prior to executing the command.

Not forgotten to go into /tmp. Did not see: I needed to copy ~/avidemux2/cmake/cmake_compile_check/libva_hevcdec.cpp first into it.
Seems to be successful, did create this binary:

Thanks, this explains why HEVC gets detected as supported. Now it would be nice to find out, where it comes from.
