This is what I tried, but it made no difference. Is there some other way for me to try?

1) in creating the AppImage, I ran the following 2 lines. The 2nd line is the usual.
export "LIBVA_DRIVERS_PATH=/usr/lib/dri:/usr/lib64/dri:/usr/lib/x86_64-linux-gnu/dri:/usr/lib/aarch64-linux-gnu/dri"
/proj/appimage/linuxdeploy-x86_64.AppImage --appdir=AppDir -o appimage ...
That made no difference.
2) so I did the full build again, using the export line first and then ran linuxdeploy to make the appimage.
Still no difference.

well, we are c++ and thus *I think* we can try to hardcode this like I did with DRI3 disable patch ...

diff --git a/cinelerra-5.1/cinelerra/main.C b/cinelerra-5.1/cinelerra/main.C

in your case just single setenv() should work,I hope?

just replace variable name and second argument (long string in "") .... ?

The reason I know it made no difference is because instead of the path being /usr/lib/dri:..., I changed it to exporting the path to a dummy value of /etc/fstab instead and the vaapi and vdpau settings still worked. Any suggestions?
