If you use the WxWidgets (default under Win32 and Linux) or the Mac OS X interface, you can open an information window (menu "window"), where you are able to see the used codecs while playing your file. Furthermore, you can have a look the messages output (can be found in the messages-window or in the console). There, you can find the fourcc-codecs and the used modules (and various debug stuff, which is not relavant for you).

Please keep in mind that Matroska (*.mkv) is only a container format and certain codecs, which might be used in it, aren't supported by VLC.

Best regards.

Sorry, my response was a bit to technical.
I try to make it easier in some steps:
1) Play your file with VLC
2) While playing it, search in the menus for an entry called "Information" (or slightly similar)
3) Push it and have a look at the resulting window. It should some two streams listed in a table, where you can look of what kind of encoding your mkv-file consists.

(4) If you cannot find it, feel free to send me a sample file to fkuehne -at- users.sf.net, so I can have a look at it (if it's smaller than 50 MBs). I'm sorry, but I cannot describe the interface under Windows better, since I do not have such a computer and it has been quite a while ago that I used VLC under Windows.

Best regards.

I'm having the same problem (0.7.2 on Mac OS 10.3.4). Audio but no video. The Matroska file generates this error in VLC:

main: no suitable decoder module for fourcc `undf'.
VLC probably does not support this sound or video format.

Seems pretty clear that VLC can't play it, but is there any other way I can view this file on a Mac?

thanks,
alison

It's possible that MPlayer OSX can play this, but not that likely. I can't test that since I have neither MPlayer nor such a file.

Where could I find a list of compatible codecs fwith works fine VCL guys?
In my case there is just sound, no image as the others. Check what the "Error Window" says:

"mkv: unknow codec id=`V_REAL/RV40'
main: no suitable decoder module for fourcc `undf'.
VLC probably does not support this sound or video format."

And in the "Info Window", under Properties my file contains 3 Streams, check it out please:

Stream 0
Codec undf * this one should be our problem.
Language English
Type video *
Resolution 720 x 384
Display Resolution 720 x 384

Stream 1
Codec vorb
Language English
Type audio * this one should be the audio one, right?
Channel 2
Sample Rate 48000 Hz

Stream 2
Codec spu
Language --
Type subtitle * This is the subtitle

Well please don't tell me I am right and there is no way to play it on my Mac . There is no codec translator avaiable on the market?

Thanx and best regards,
Rafael

"V_REAL/RV40": well, this is self-explaining: RealVideo was used to encode the video, which is proprietary and not supported by VLC. A list of all supported stuff can be found on the Features-page.

It might be supported with additional, so-called Helix-Codecs by MPlayerOSX, but I'm not sure about that. Have a look at their website for details.

Btw. The RealPlayer for OSX cannot play these files too, as it does neither support Ogg Vorbis (the used audio codec) nor Matroska (the used encapsulation-format/file-format).
