[FFmpeg-user] Issue capturing stream

Thank you for your answer. The reason for linking was because I thought the
screens were helpful. I did provide "a copyable" command line in the
thread. But I see your point.

I did try the following:

ffmpeg -i
-map 0:v -map 0:a -c copy test.mkv

I am still getting an error, but it is working fine if I use "-c:v" instead
- which I though only copied video?

I am unsure how the command line should look - maybe you could advise?

I tried -dn, but I could not get ffmpeg to accept it.

Best regards,
