This is the command mpginfo that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
mpgtx, mpgsplit, mpgcat, mpgjoin, mpginfo, mpgdemux - manipulate mpeg files
SYNOPSIS
mpgtx command [ options ] file [ range | file ] ...
DESCRIPTION
mpgtx can split and join MPEG files in various ways. Three file types are currently
handled (more to come): MPEG 1 Video files, MPEG 1/2 Audio files (mp1, mp2, and mp3), MPEG
1 System files (audio and video files), MPEG 2 Program files (Experimental), MPEG 2
Transport files (demultiplex and info modes only). mpgtx is a GOP (Group of Pictures)
based editor. This means that mpgtx cuts MPEG files on a Group Of Picture basis, not on a
frame-by-frame basis. A typical GOP duration is about 0.5 sec (approx. 15 frames),
limiting the maximum accuracy of mpgtx.
COMMANDS
-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.
In addition, when invoked with the names mpgjoin, mpgcat, mpgsplit, mpgdemux, tagmp3 or
mpginfo, mpgtx will modify its behaviour in the following ways:
mpginfo behaves as mpgtx -i
mpgsplit behaves as mpgtx -s
mpgjoin behaves as mpgtx -j
mpgcat behaves as mpgtx -j -o -
mpgdemux behaves as mpgtx -d
tagmp3 behaves as mpgtx -T
OPTIONS
-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 infos will be displayed, only 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.
RANGES
Each range must follow a filename or another range. A range in an MPEG file can be
specified using one of this three notations: Note for OSX Users: Ranges must be enclosed
in single or double Quotes!
[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.
VALID VALUES
Values of ranges can be specified in seconds or as a byte offset.
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.
RETURN VALUE
All programs return 0 upon successful completion and 1 on failure.
EXAMPLES
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.
