Command line tool to demultiplex video

[lovyagin]

Hi everyone, could you help me please to find a good (free) and reliable program that demultiplex MPEG-2 videos to elementary stream, to be run from command line and support program and transport streams as well as DVD .VOB files.

I know that mplex from MJPEGTools can easily multiplex MPEG-2 and MPEG-1 streams, but I could not find such a good "inverse" application...

ffmpeg, "ffmpeg -i input.mpg -vcodec copy -f mpeg2video ES_Video.m2v -acodec copy -f mp2 ES_Audio.mp2"

tsmuxer might also work.

http://mpgtx.sourceforge.net/ but I don't think it support dvd vobs.

ProjectX is also worth a look, can use it in CLI or GUI mode.

Baldrick, thank you, i think ffmpeg will work well, just unfortunately I always should manually specify destination files formats, names and extension. What if video has more than 1 audio track?

Ok, will try tsmuxer soon, and mpgtx does not support vob for sure unfortunately.

Safesurfer, thanks, ProjectX sounds promising too but I can't find CLI there

It's just not well documented, if you run ProjectX from a command prompt you'll see the switches available (see below.)

I use it like this in a batch file for demuxing my TV recordings from my tuner card captured with GBPVR.

"C:\Program Files\Projectx\projectx.exe" -ini "C:\Program Files\Projectx\x.ini" -demux "%~dpn1.mpg"

You can set certain parameters in the .ini file in the GUI which will then work on all projects in command line use.

quick CL usage:
Note: CL doesn't load the GUI components, except with switch [-gui]
<without options> ...starts the GUI
switches and inputfiles can be in any order

options:
[-ini <path + inifile>] ..use that specified iniFile instead of the standard
[-dvx1] ..create a .d2v ProjectFile on demux
[-dvx2] ..create a .d2v ProjectFile + .ac3.wav (RIFF WAVE Header)
[-dvx3] ..create a .d2v ProjectFile + .mpa.wav (RIFF WAVE Header)
[-dvx4] ..create a .d2v ProjectFile + .ac3.wav + mpa.wav (RIFF WAVE Header)
[-out <path>] ..use that specified directory for output
[-name <filename>] ..use that specified filename for output
[-cut <file>] ..use that text based file as cutpoint list
[-chp <file>] ..use that text based file as chapterpoint list
[-id <tokens>] ..use only these (P)IDs, separated by comma ","
[-gui] ..display the GUI using all given CLI options
[-log] ..write the normal logfile
[-saveini] ..save changes made bei CLI in active .ini
[-split <xxx>] ..split output at xxx MB
[-demux, -tom2p, -topva, -tovdr, -tots, -filter] ..action types

It will work on program and transport streams, as well as VOB files.

Hope this helps.

Another option is DGMPGDec, see http://neuron2.net/dgmpgdec/DGIndexManual.html#AppendixC for command line instructions.

Thanks a lot, I will try them soon since ffmpeg I found to work a bit slow, do not know why.
