Linking problem at latest Ubuntu about kvazzup HOT 6 CLOSED

Hi.

Kvazzup doesn't have any dependencies on libAV or FFmpeg, so it must be that openHEVC is causing this problem. I have not encountered this problem before, but my testing on Linux systems has not been extensive. Since the code in openHEVC is 8 years old, it does seem that this is not due to any recent update in OpenHEVC, but something to do with either

1. the way OpenHEVC has been built or
2. the way Kvazzup has been built or
3. the build environment.

Have you tried installing libAV or FFMpeg? The errors seem to indicate that those dependencies are not found.

Another question is that have you tried using QtCreator? I'm not sure how this would solve the issue, but that is what I've been using.

OpenHEVC is also a bit funny in the way they use branches, the default branch is behind but I think we have usually used ffmpeg_update branch

from kvazzup.

That is true, I should probably check which branch I have used (and works) and document it in the build instructions.

You are both right!

Also this worked for me at ffmpeg_update branch:

I am going to close issue when will be tested on kubuntu 21.10.
