you can use ffmpeg
https://ffmpeg.org/ffmpeg-filters.html#psnr
eg
Code:
ffmpeg -i muxed.mkv -i original.mkv -lavfi "[0:v]settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]psnr" -f null -
If it's "infinity" then streams are the same. Anything else means different
The timecodes have to be the same, otherwise ffmpeg might be comparing different frames.
