I tested vaapi presets with the compile of the new CinGG release. Previously vaapi was not working for me in either encoding or decoding. Now I have no errors or warnings. I used the Big Buck Bunny 1080p and 30 fps file with h264 codec. With some presets the rendering fails with the following errors in the terminal: - av1_vaapi_10b420.mp4 [av1_vaapi @ 0x7d304c2269c0] No usable encoding profile found.

PS: Compilation time got a lot longer, is it because of the new patches? PPS: I have not followed the various threads very well and so I do not know the conclusions you have reached....
