It seems that Dav1d is developed by VLC together with ffmpeg. They say it is software only and does not uses any GPU acceleration: https://www.videolan.org/projects/dav1d.html It would be to try with Nvidia hardware to confirm. It can use AVX2 in decoding, though. Do you have to enable this option or is it by default? https://code.videolan.org/videolan/dav1d It seems that dav1d is not a very up-to-date project; if I wanted to compare with libaom I just need to disable "-enable-libdav1d" in configure? > hm, ah, second error! Was it 10bit hevc by the way? Yes, it is a file 10-bit: "pix yuv420p10le"; Color Space: bt2020nc; Color range: TV (mpeg). Has anything changed between CinGG with ffmpeg6 and 7, since with appimage I have no problems loading ("second error"). [PS: Following the manual, I tried to start CinGG(ffmpeg7) with: CIN_HW_DEV=vaapi ./cin Now loading works without errors and playback works with a certain percentage of GPU acceleration (8-20%). If you try scrolling, however, there are continuous freezes and artifacts. But there are no messages and errors in the terminal. -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
