I'm trying to see if there is a way to determine if a movie file was ripped from a DVD/Blu-ray. Currently the only way I can check is looking at the ffprobe output and checking the tags property:
"_STATISTICS_WRITING_APP-eng: MakeMKV v1.14.5 win(x64-release)"
This tells me it was created by the MakeMKV application. If I have the video properties is there a way to check that it's a straight copy of a DVD/Blu-ray?
- Bitrate: (7,209 kb/s)
- Resolution: (480p)
- Bit Depth: (8)
- Frame Rate: (23.976)
- Color Space: (YUV)
- Chroma Sampling: (4:2:0)
- File Size: (4.35GiB)

I have a thought. Using the data I have above could I calculate the bitrate without using file size and see if that value is close to the value provided by mediainfo? I have a bunch of files(movies/shows) and I want a quick way to determine if they've been re-encoded after ripping.
I extracted the video stream out of the movie just for an example.

You could do a straight disc rip, or take the output of a disc mastering program like scenarist and they'd be identical.
why? are you dmca enforcer? help? hell no.--
