demuxing video & audio streams from a mkv file

[minaust]

Pardon me if I sound frustrated, because I am. As a favor for a friend, I agreed to finish up a video prior to the video being authored to a DVD. When I got it, it was in Matroska format. MPC will play it, but VirtualDubMod chokes on it. What I need to do is extract the video & audio streams without transcoding. Any have any ideas? Am I missing a filter, that's why VirtualDubMod won't touch it? VirtualDubMod 1.5.10.1 says “Birtual block not found.”

Man, I hope somebody has an idea. Grrrrrr......

VirtualDubMod is an obsolete tool not suited for MKV processing at all. Stop using it.
You can extract / merge individual streams from / to MKV very easily with mkvtoolnix (http://forum.doom9.org/showthread.php?t=155732)

Bingo! Worked like a charm! Thanks for the heads up.This'll teach me to volunteer, tho. And VDubMod is off my list of Matroska tools. It's still a valid avi util tho.

For the record, there's a plugin for VirtualDub (not VirtualDubMod) for opening MKVs. It works quite well. There's also some other plugins here for handling other audio/video types. http://home.comcast.net/~fcchandler/index.html
The DirectShow input plugin can also be very handy. http://forums.virtualdub.org/index.php?act=ST&f=7&t=15093&hl=mkv&
Not that you need VirtualDub for extracting MKV streams, but it might be handy to know for future reference.

MKVcleaver is also a handy tool to have for working with MKVs. It'll extract streams to their raw format. I don't think you can do that using MKVToolNix.
