The decoder filter doesn't seem to support H264 High422 and High444 profile. I use ffmpeg to encode x264 4:4:2 and 4:4:4 content. Also tested x264rgb 4:4:4.
Decoder is the same as in ffmpeg and so it supports both High 4:2:2 and High 4:4:4 profiles. Why do you think it doesn't? How did you tested that? Sample file?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
