hi list,

okay, here I have 2 outputs from different messages:
one is the output of "Codec-Information"
and the 2nd is the output of "vlc -v"

[00007fcfe0001150] mkv demux warning: EOF
[00007fcfe0001150] mkv demux warning: cannot get block EOF?

are these messages something, which tells you anything ?

First, sorry for the long delay. My main computer is in the shop (motherboard issues), so my email access is a bit unstructured recently.

Second, did you find a solution to the issues?

Unfortunately, I don't see anything helpful in the messages. The file video is h264 mpeg-4, which is common, and the sound is opus - which I think is unusual in a mkv file, but should be totally supported (it is more common in webm files). So, the vlc should be able to play the file.

I'm not sure if the "cannot get block EOF" (EOF = End Of File, usually) error is meaningful. It's possible that there is an error in the encoding. Have you tried converting to a different format? Or even just re-encoding in the same format? Ffmpeg is good for this, as is Handbrake.
