mpgsplit(1): change mpeg files

NAME

-i: prints information about files, such as duration, dimention, bitrate, etc.
-j: joins files (ranges may be specified, see the RANGES section).
-s: splits files according to the specified ranges (see the RANGES section).
-d: demultiplexes composite mpeg file.
-T: manipulates ID3v1 tags from mp3 files (see tagmp3(1)).
-h: prints a (not so) short help message.
-v: prints version and exit.
-#: where # is a number, splits the given files in # parts.
--force: enables joining of incompatible files (some players are very robust)
--no-parachute: prevents mpgtx to try to catch SIGSEGV signal. This is usefull for debugging.

-f: force overwriting of files, never ask.
-Ax: Change aspect ratio of mpeg. Valid are 1,2,3,4 for 1:1, 4:3, 16:9, 2.2:1
-P: Keep junk or unusual headers in splits
-X: Desperate mode, search the whole movie for a valid PACK. In addition with option -N no search information will be displayed, only the end summary.
-N: Suppress progress output to the console. Speeds up operation a little on most Systems and much on Macintosh OS9. Suppress time line check in mpginfo mode.
-b NAME: each output file will have the basename NAME
-o FILE: FILE will be used as the output file (used with the join command). if FILE is -, standard output will be used.

[a-b]: from value a inclusive to value b inclusive. If you want half opened ranges, you may want to use ]a-b], [a-b[ or ]a-b[.
[n/ntot]: the n th part out of ntot. [1/4] would result in the first quarter of the specified file.
{a-b-...}: with a , b , ... in ascending order. Split specified file at given boundaries. {55M} therefore means from beginnig of file to 55Megs and from 55Megs to the end of file.

Time Format: HH:MM:SS.SS where the HH: part can be omited
Offset Format: a number optionally followed by M for Megabytes k for kilobytes
Omitted Values: An empty value is valid and is equivalent to the corresponding file boundary: [-10M] are the first 10 Megabytes of the file. [1:10:04-] from 1 hour 10 minutes 4 seconds to the end of file.

mpgjoin movie1.mpg [-0:32] [45M-75M] movie2.mpg -o joined.mpg: joined.mpg will contain the first 32 seconds of movie1.mpg followed by 30 Megs of movie1.mpg starting at 45 Megs followed by the whole file movie2.mpg
mpgtx -124 myfile.mpg -b output: will split myfile.mpg in 124 parts with names output-001.mpg to output-124.mpg
mpgtx -i Wazzup.mp3: will print infos about given file such as duration, bitrate, but also album, track, song name if this file has an ID3 tag.
mpgcat myfile.mpg [2/2] | lpr: will redirect the second half of myfile.mpg to your printer, emptying it from toner and paper and make you be fired by your boss... Use carefully.
