>> Andrea, can you test attached patch + this opts file put alongside >> test 4k HDR video decodable by hardware?
I compiled with the patch and put the opts in .../bin/ffmpeg. I don't think I know what and how to test. I loaded the iPhone13_tonemapping_checker_rev2.mp4 file you had provided. The playback performance is good (even in reverse, with only a few freezes). However, the video card does not activate and the CPU (not particularly busy) does everything. The behavior is the same even removing the opts. Suggestions? PS: the same is true with the lines for zscale that you asked to put in the manual. Do I have to do an opts on it? How do I text it? I also don't quite understand how the line you report works. -- Cin mailing list Cin@lists.cinelerra-gg.org https://lists.cinelerra-gg.org/mailman/listinfo/cin
