Easy way to demux video & audio

[ariga]

Any tool that can separate the audio and video from a .rmvb file ?
I guess mplayer should do it. But the video didn't play when I tried.

.Install this (http://sourceforge.net/project/showfiles.php?group_id=82303&package_id=87719)
.Put the .ax file is your %windir%\system32
.Register the .ax directshow filter with regsvr32.exe
.Use graphedit to split whatever you want the way you want.

mplayer is a player, it doesn't split anything.

In the follwing example, an RM file is 1st split, then muxed into matroska:

I think DTDrive can do it too, in the Utility sticky.

Had searched for "demultiplex/split" but ended up with some discussion on Matroska. Hoped there'd be a straightforward way to do it. I only guessed mplayer's dumpaudio/dumpvideo option would work. Will give DTDrive (or other utils) a shot first.

If it doesn't work will "graduate" to graphedit method. Never used it before. The screenshot looks similar to the output of GSpot though. Even with this method I'd end up with a matroska file that has raw audio & video. Guess it should be possible to stop at just the splitting phase and not have to decode the audio & video ?

GraphEdit was released at the very begining by Microsoft, way back before
the existence of GSpot.

All depends on which filter you selected for rendering the output file. (I mean the most right box)
We have been using this method to mux any type of codecs within
the matroska container. You will be surprised to see the variety of the different used codecs.
Rendered files are perfectly playable with any player supporting matroska. You could even play them very smoothly with WMP if you have the necessary DX filters,.

No, it is useless, you need to output the demuxed codecs somewhere, otherwise, what's the purpose of all this issue.
Re-muxing them back into another container is a very efficient and useful way.

ok... I began learning & experimenting with video just a month before I joined the forum! :) So please bear with my ignorance.

Well, I was looking for something that does a
.rmvb(audio+video) file => .rm(no video) file + .rmvb(no audio) file

get dtdrive and extract your streams

Thanks for the replies. dtdrive did it. Tried rmmuxer too. "Easiest" ? Hmm.. demuxing with "Merge" button is not quite intuitive. ;) But sure does both mux/demux.

EDIT: Wouldn't it be nice to have rmeditor/dtdrive/rmmuxer capabilities in just one tool ?
