[FFmpeg-user] search a DVD via the following regex

[Mark Filipak (ffmpeg)]

I need a way to search a DVD via the following regex, then display the hex of the captured bytes; 
either a Windows or a Linux method will do.

/\x00\x00\x01\xB5(\x11.|\x12.|\x13.|\x14[^\x82]|\x15.|\x16.|\x17.|\x18.|\x19.|\x1A.|\x1B.|\x1C.|\x1D.|\x1E.\x1F.)/

The DVD barcode and returned captured bytes would be very valuable to me (and perhaps to many 
users). A script that I could run on my own would really float my boat.

Thanks so much,
Mark.

Of course you want to know why, eh?

I have yet to see a DVD that has this: 0x00 00 01 B5 1? ??, where '? ??' is other than '4 82' (i.e. 
MP at ML plus !progressive_sequence plus 4:2:0). The above regex performs such a match.

It's the 'sequence_extension' header ID metadata followed by 'profile_and_level_indication' -- the 
allowed combinations are shown in the table, below -- followed by 'progressive_sequence' followed by 
'chroma_format'.
