Comment (by edotom):
I tried again at home but as soon as I tried to upload first file I got
disconnected.
Anyway.. I'm going to try to explain.
I have to convert many mkv files and image files and in the end join them.
When I convert a mkv like the following I get a message: (Could not find
codec parameters for stream 1: does it mean that I don't have the right
codecs to convert mkv to mp4?). Can I send that file via email?
