>> 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.
you create file with .opts extension in same folder where your main_media_file.mov located.
You name it main_media_file.opts
You put test lines there.
You might need
RADV_PERFTEST=video_decode set before you launch cin. I usually just launch cin path_to_test_media/main_media_file.mov
It should pick up .opts file from there.
I did not try to put those lines in global decode.opts
you also need to set cin to Vulkan decoding (should be already in git).
