I have noticed that when I copy 2vuy video streams with FFmpeg, the files are different in Quicktime. I am using the below command:
ffmpeg -i infile.mov -vcodec copy -acodec copy outfile.mov
In the Quicktime Movie Inspector, the infile is listed as 8 bit Packed YUV 4:2:2 (2vuy). The outfile is listed as '2vuy'.
Has anyone else dealt with this? Thanks in advance for any responses.
