HI,
I try to set up hw accel decoding for AMD laptop, but if I enable vaapi or vdpau I see a 'file not found' error. Hw accel  works OK for the rest of the software. I unpacked appimage and removed boundled libvdpau.so, this results in working hwaccel via vdpau. The same with if I start cinelerra with the LD_PRELOAD environment variable. Maybe this library should be excluded from the appimage bundle?


but may be cin will stop to work (on systems without this lib) because missing library?

I hear somewhere you can dynamically load so on linux instead of linking to it at build time, but no idea if it works with ffmpeg libs ....

some more search showed chromium dlsyms vaapi ...

at the end 

so may be this can be made to work with libav too (while 6 years ago devs were not thrilled by this idea:

thanks for (re) testing!
