Error decompression on mkv

[cassiosteel]

Hello everyone
I need to open a mkv file frame by frame, so I created an avs file with the command DirectShowSource("C:\...") but when I open it on virtualdubmod I can't see any frame, but on a bar it's shown this error: Error decompressing videoframe 0: the source image format is not acceptable. (error code -2). How can I fix it?

The VirtualDubMod project is dead for years now.

Also the Matroska support in VirtualDubMod is so much outdated that even the Matroska web-site warns you about it :rolleyes:

Please update your outdated VirtuaDubMod to an up-to-date VirtualDub (http://virtualdub.sourceforge.net/). Then use Avisynth with FFmpegSource2() (http://code.google.com/p/ffmpegsource/downloads/list) to open the MKV file...

Alternative you may want to have look at Avidemux 2.6:
