ProRes wrong profile? #1007

Their link refer to it as having a 4444 profile but MediaInfo show a 422 profile. So i'm not sure who is incorrect.

Issue is that the profile is not available directly in the bitstream, we need to trust the 4CC. Trusting https://wiki.multimedia.cx/index.php/Apple_ProRes , 4CC for 4444 is ap4h, not apcn. And if one decides to put some 4444 content with a apcn 4CC, I don't see a way to detect it easily (maybe checking the bitrate? a bit complicated, I would not do it now)

Oh i see +1 To be honest i just tested now with FFmpeg and it show the same profile as MediaInfo.
