How to mux WMA in MKV?

[DeathTheSheep]

I looked all over for how to mux WMA9pro into MKV (or even OGM) and came up dry. Here are the things I read:

1. Asf2Mkv recorder (it looks like this thing has nothing to do with ripping a wma's audio and sticking it in an mkv. Correct me if I'm wrong).
2. MkvToolnix (no option to select wma, GUI refuses wma input).
3. Directshow gabest matroska muxer (output is often broken, sometimes crashes, and other times the output is choppy and skips a lot).
4. Haali mkv multiplexer--part of mkvsplitter (doesn't connect to wma file in graphedit).

Again, I don't want to convert the WMA audio. I just want to stick it in an MKV (or even OGM) container. Is there any way to do this with modern tools and/or muxers? If not, is there any way at all?

Thank you.

Really? Huh. That's the only way I could get to reliably work back when I needed it, but I don't anymore, so it's been a while. What sort of WMV is it? I never tried WVC1 or WMVA, or some of the less common codecs; ie, I've only tried it with WMV1/2/3.

If Gabest's muxer fails, nothing will work, besides re-encoding.

What happens when you mux with Gabest's muxer and then remux with MKVToolnix? You have to remember that Gabest's muxer has not been updated in over 2 years and remuxing with mkvmerge can sometimes help. I've even had situations where muxing with Gabest's muxer then remuxing with his muxer helps. However, I've never worked with WMA9pro so your mileage may vary.

AFAIK Matroska does not explicitely support WMA9(pro), it only deals with it through ACM mode (I think that is what Gabest's muxers does), which may certainly fail if the stream is incompatible.

i also tried similar things with wma9 pro:

i muxed .wma (wma9 pro - get the sample here (http://download.microsoft.com/download/winmediatech40/Utility/1.0/W98NT42KMeXP/EN-US/6channel.exe)) content into .avi (using graphedit and "avi mux" (qcap.dll)), into matroska (using gabest's muxer) and finally also into .ogm (using tobias' ogm multiplexer) and it worked in all three cases!

When I used Tobias' Ogg DS muxer 0.9.9.6 and his oggmux.exe GUI (0.9.5.1), there was no option to import wma streams, and no method seems to work with it. The directshow muxer won't accept the wma raw audio pin. Is the muxer bond referred to a different version?

AVI MUXER. My goodness. It can be argued that it indeed "worked," but the resulting file was jumpy, and the video quality took a quantum leap downward with the introduction of random spurts of blockiness and skipped frames. Wow.

Just for fun, though, I tried to open the AVI with VirtualDubMOD (yes, the old, ancient, decrepit, worthless, infamous VFW client that most of the world still uses), and tried to save an MKV. The resulting MKV was a bit better than the original AVI, but it still suffered from random skipping and a/v sync issues. Finally, having lost heart, my hands moved on their own to mux the dang thing into an OGM...

And it worked, but was a bit out-of-sync.

edit: JEEZ I'm tired. Sorry guys...look like I spoke too soon earlier when I reported correct sync. I didn't watch the file the whole way through ;)
