Blue Ray Question

Ron Barnes
Hello All,

 

I know there are tools out there for this question but I'm hoping FFmpeg can
handle things.

I have an old blue ray that I would like to shrink.  The only problem is
when I open the BR in File Explorer there is no way of knowing which files
are the main movie and what order those files are supposed to be in.

 

Can FFmpeg or a tool of FFmpeg help in determining the answer?

 

What is the main movie files and what order should they be in?

 

Thanks,

 

-Ron

No, ffmpeg won't help you in determining that
Blu-rays can be authored in many ways. The main content is most probably
the largest file. For a feature film, around 20 GB for a single-layer BD or
40 GB for a double-layer BD.
Other files you will see are extra content, trailers, logos, whatever. just
look for the largest file.
Keep in mind if it's a commercial BD, it will be encrypted and ffmpeg won't
decode it.
