i want to create matroska files with the mkvmerge application under  
Linux. My problem is, that the fps (default-duration) are not set in  
the final .mkv file.
The source is a .mp4 file with MPEG-4 encoded video. Is it possible  
to read the fps out of MPEG-4 encoded video? If i use an .avi (with  
the same source video) the fps are set correctly.

Is this a big or working as intended? How can i fix this? Should I  
reencode the files, maybe to an other format?

Btw. Is there an editor for changing/ setting the Matroska values  
(metadata/ tags) in Linux (after the creation)?

thanks and best regards,
