Patman86

Those patches are not compatible with versions greater than R54.

not only the vapoursynth alt demuxer has problems with R57, the original file in ffmpeg cannot bypass R57 either. I'll take a look where the problem is.

Could you also detect this in earlier versions?

and what about other versions of x265?

X265 aMod etc.

Please run the test again with the current release. There was an error in the code. I hope the result is now almost identical.

The graphs look quite good except gcc13.2.0, how are the data of the plain version?

Have you done some more testing? Are there any new findings?
