Well pcm isn’t really a codec the same way mp3 is, I’m guessing but all the
decoder does is probably just parse the LPCM format info like bit depth, rate
and channel layout.

I’m not sure if it’s you or me, but I feel like something is definitely getting
lost in communication…
Referring back to the command in your original message:
> C:\CMD & tiny apps\ffmpeg>ffmpeg -i B:\BDMV\STREAM\00000.m2ts -vf
> "telecine=pattern=5555,bwdif=mode=send_frame" -avoid_negative_ts 1
> -analyzeduration 80000000 -probesize 80000000 -c:v libx265 -crf 20 -preset
> medium -c:a copy -c:s copy C:\AVOut\8.MKV
For ffmpeg to figure out how to read a m2ts file as found on a pressed
commercial BD-ROM designed to play in regular BD players and not used as a
simple data disc, you need to prefix the mount point or root of the filesystem
with bluray:, and possibly also specify which part to read, with parameters
such as angle, playlist, and chapter.
Again I am not sure if escaping or quoting is needed but assuming you can “cd”
to “B:\” in the windows command line and it shows the BDMV folder when you list
the directory entries, I think the command would look something like this?
> ffmpeg -i bluray:B:\ -vf "telecine=pattern=5555,bwdif=mode=send_frame"
> -avoid_negative_ts 1 -analyzeduration 80000000 -probesize 80000000 -c:v
> libx265 -crf 20 -preset medium -c:a copy -c:s copy C:\AVOut\8.MKV
And that would let ffmpeg navigate to whatever the default program is on the
disc. I’m not sure if it is always the main program or if it uses the first
playlist if you don’t specify which one.
But you basically need to do this if the elementary streams have not yet been
separated from the menu, studio/distributor logo hero sequence, etc. because if
it was copied directly from the UDF (decryption having been handled by that
nifty tool) the media is still in the very closely interleaved Blu-Ray specific
format as necessitated by the bitrates and typical player capability.
To be honest I actually don’t know if I’ve ever had a computer bluray drive, I
authored an image for reference, to check the errors I get if I do the same
thing (I didn’t put any Sony subtitles in there so that’s missing but you can
see the difference when you use the bluray protocol vs regular file. Even with
copy protection set to completely open it is necessary.

So if TITLE was the root folder of the disc file structure, I would need to do
this to read all playlists:

Simply setting the m2ts files as input causes a bunch or decoder setup errors.

Thanks for that tip! I did not know Thunderbird was still alive and kicking,
friends at FireFox should help them with some exposure. I’ve only just started
setting it up but it checks all the boxes for me :D
