I've done some research on the hardware acceleration problem with appimage. Non-working hardware acceleration is a drawback of portability. There is no general solution available.
I've found that I can preload system libraries ahead of bundled with appimage with LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ in case of Debian. This solution works for me in case of vaapi and vdpau acceleration. Vdpau gives me a more smooth playback of 4k h264 video.

Best regards,
Andrey

I tried compiling CinGG with the --with-hwaccel=auto option but it is
not recognized:

configure: WARNING: unrecognized options: --with-hwaccel

Any advice on what I could do?

oh, this is ffmpeg's binary runtime option, not compile time thing ...


I looked for the library "libvdpau.so" in ../cinelerra5/cinelerra-5.1/
but I can't find it...


well, appimage creation procedure add it as dependency from system, I think ...

as long as you do not use appimage you should be safe from this particular hazard



PS (@Phyllis): In ../thirdparty/src/ there are still the ffmpeg4.4
files and patches.
I don't remember if they were for something or we forgot to remove them.
