I just upgraded to Kubuntu 22.10, the update was successful completely minus FFmpeg.

Things I've tried:

  • Install an older FFmpeg from Ubuntu sources
  • Install master FFmpeg from source
  • Install FFmpeg 5.1.2 from source
  • Install FFmpeg 5.0.1 from source
  • Install older libav stuff from Ubuntu sources
  • Reinstall current FFmpeg from Ubuntu sources
  • Reinstall libva2 from Ubuntu sources
  • Reinstall libva2 and libva-utils from GitHub (as per this post)

This always results in the same thing:
ffmpeg: symbol lookup error: /lib/x86_64-linux-gnu/libavcodec.so.59: undefined symbol: vaSyncBuffer
It seems as if some other dependency of FFmpeg is calling libavcodec59 and is having issues with it

Things I cannot do:

  • Uninstall libva2, as it will uninstall my desktop environment
  • Revert to an libva2=2.14.0-1, same dependency issue with my DE

From what I have gathered, this appears to be an issue with libva, some dependency from FFmpeg requires libva>=2.16, but the Ubuntu sources don't have that version yet and that dependency doesn't state that requirement

I do have some amdgpu drivers installed, so let me know if you need to know more about them.

Update

I did some more searching, and this is the output from vainfo:

libva info: VA-API version 1.8.0
libva info: Trying to open /opt/amdgpu/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: va_openDriver() returns -1
libva info: Trying to open /opt/amdgpu/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

So I'll be researching more into the amdgpu drivers, as I've had issues with those before

Versions:

Ubuntu - 22.10 Kinetic Kudu (Kubuntu)
kernel - 5.19.0-23-generic
libva2 - 2.15.0-1 (Ubuntu source)
FFmpeg - 5.1.1-1ubuntu1 (irrelevant in this case)

libva2 - 2.16 (GitHub, possible installation failure)
FFmpeg - 5.1.2 (git, no change)
FFmpeg - 5.0.2 (git, no change)
FFmpeg - 4.4.2-0ubuntu0.22.04.1 (Ubuntu sources, no change)

Reinstalling the various libav stuff from where ever did not change anything either

NOTICE

Unless your output to vainfo reads like:

libva info: VA-API version 1.8.0
libva info: Trying to open /opt/amdgpu/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: va_openDriver() returns -1
libva info: Trying to open /opt/amdgpu/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

where libva is trying to load intel drivers from the amdgpu drivers location, this solution may not work for you. I repeat, I only discovered this solution because the parts that are /opt/amdgpu/lib/x86_64-linux-gnu/ should instead read /lib/x86_64-linux-gnu/ or /usr/lib/x86_64-linux-gnu/

Solution

Uninstall literally everything amdgpu. Drivers, core, mesa, va, dkms, everything.

I would prefer to use my GPU to encode video in x265, but the resulting file sizes are enormous compared to using the CPU, so I don't need amdgpu drivers. Let alone that my fps drops from 60 to 5 with amdgpu installed
