WMV to MKV?

[gdb66]

I want to convert some WMV HD movies to MKV format. MKV just plays better on my HTPC and is easier to add subtitles to.

I found a tool from Riverpast called VideoCleaner, but this not handle multi channel audio :o

Is there any tool out there that allows me to extract the raw H.264 video stream and convert the multichannel audio to a raw ac3 file? Using MKVMerge I can then put the raw streams into a MKV file

:thanks:

WMV HD doesn't have an H.264 stream to extract, since its probably encoded in VC-1.

Perhaps MPlayer could demux those files:
mplayer -dumpaudio -dumpfile audio.dump file.wmv
mplayer -dumpvideo -dumpfile video.dump file.wmv

WMV HD files do not contain a H.264 video stream; it is probably VC-1 or WMV9 video instead. I'm not sure how mkvmerge handles WMV elementary streams. If it doesn't, try to mux video and audio to AVI and feed that directly to mkvmerge. MEncoder should do the trick: mencoder -oac copy -ovc copy -o video.avi file.wmv

Edit: You can also use mencoder to encode the audio stream to AC-3 if MPlayer can play it (I don't remember how well multi-channel WMA decoding is supported). But try direct stream copying first.

gdsmux will probably do the job

Use the Directshow matroska muxer from Gabest.

x264's play better than wmv's?....wtf....make sure you have the right codecs/settings....they require much less power to run...plus you will experience quality loss each time you encode

Is VC1 really supported by MKV? I'm trying the same thing ATM.

But the reason for it I have a WMV File with VC1 codec and WMA3 6ch Audio. So I need to demux the file and convert the audio somehow to something sweet like AC3/DTS. I would prefer MKV then (if I ever figure out how to get there:)) but if WMV would supports AC3 and is more compatible with VC1 stick with it.

Yeah VC1 is supported, it's how alot of people are getting their HD DVD's into the container.
