Installed Andrey's recent cinelerra-5.1-20250104.suse15.x86_64.rpm package on Leap 15.6 on two different Intel based hw, and tested qsv and vaapi presets without issues 1) Intel Arc Alchemist w/ A750 dGPU (2023) av1_qsv_8b420.mp4, qsv_10b420.mp4 hevc_qsv_8b420.mp4, hevc_qsv_10b420.mp4, hevc_qsv_10b422.mp4 av1_vaapi_8b420.mp4, vaapi_10b420.mp4 hevc_vaapi_8b420.mp4, hevc_vaapi_10b420.mp4, hevc_vaapi_10b422.mp4 2) Intel KabyLake w/ UHD 620 iGPU (2017) hevc_qsv_8b420.mp4, hevc_qsv_10b420.mp4 hevc_vaapi_8b420.mp4, hevc_vaapi_10b420.mp4 The last line here is of special interest hevc_vaapi_8b420.mp4, hevc_vaapi_10b420.mp4 because Cingg deb on UB24.04 on this machine didn't render hevc_vaapi. It seems that OneVPL (libvpl) extends the codec capability also for vaapi. This has to be verified by dual-testing once more..
