Comment (by heleppkes):

 MKVs usually contain MP4-style H.264. You cannot dump that into a file and
 expect it to work. In other words, your resulting file is invalid.

 Generally, you are best advised to use a tool thats designed for
 processing video, like ffmpeg itself, if you want to seperate the video
 out of an existing file.
