Dear Phyllis, can you check if ffmpeg binary in thirdparty/ffmpeg-8.0 for this build actually list qsv in its -encoder output, if you still have this tree around?

ffbuild/config.log us also interesting, but I assume it not complained at configure/build/link times ?

Looking at ffbuild/config.log "qsv" is all over the place as in:  av1_qsv_decoder, h264_qsv_decoder, hevc_qsv_decoder, mpeg2/vc1/av1/mjpeg/vp8/vp9/vvc AND av1_qsv_encoder, h264_encoder,etc. AS WELL as deinterlace_qsv_filter ...hstack_qsv_filter, etc., qsv_decode_example.

root@fedora:/mnt0/cinelerra-5.1/thirdparty/ffmpeg-8.0# ./ffmpeg -encoders | grep qsv
 V..... av1_qsv              AV1 (Intel Quick Sync Video acceleration) (codec av1)
 V..... h264_qsv             H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (Intel Quick Sync Video acceleration) (codec h264)
 V..... hevc_qsv             HEVC (Intel Quick Sync Video acceleration) (codec hevc)
 V..... mjpeg_qsv            MJPEG (Intel Quick Sync Video acceleration) (codec mjpeg)
 V..... mpeg2_qsv            MPEG-2 video (Intel Quick Sync Video acceleration) (codec mpeg2video)
 V..... vp9_qsv              VP9 video (Intel Quick Sync Video acceleration) (codec vp9)

Question for Andrew - is there another executable that is necessary to add to the "linuxdeploy" line to create the AppImage -- I do not think so. I have commentary that states that "we need to include all executables so linuxdeploy picks all dependencies". 

Also, I ran the linuxdeploy on an earlier Fedora version that did not have either vulcan or onevpl installed -- again, I do not think that matters.
