mpegcat - Extracts structural information and PES streams from an MPEG2 video file
mpegcat { options } { file }
mpegcat dumps detailed textual information about an MPEG2 file. It also has an option for writing out a particular Packetized Elementary Stream (PES) given its id.
The original purpose of mpegcat was for debugging stream parsing issues in the gopchop cuts-only MPEG2 video editor, but it has more general utility.
To find SPU streams in a .VOB ripped from a DVD:
$ mpegcat -iDa VTS_01_0.VOB | grep SPU
131086: 0xBD: DVD Audio 0x20 (SPU 0): 2028 bytes (next marker @ 133120)
133134: 0xBD: DVD Audio 0x20 (SPU 0): 2028 bytes (next marker @ 135168)
137230: 0xBD: DVD Audio 0x20 (SPU 0): 190 bytes (next marker @ 137426)
...
To save a given stream:
$ mpegcat -iDaw dump.spu,0xBD,0x20 VTS_01_0.VOB > /dev/null
(And to view the stream)
$ gtkspu dump.spu 1
$ gtkspu dump.spu 2
$ gtkspu dump.spu 3
