Today I have a new problem...
I need to concatenate a myltiple videos (it's about 10), so 8 of them are recorded from the camera and they have the same codecs, but two of them are using another codec. So, how should i concatenate them together? I had learn information from this link https://trac.ffmpeg.org/wiki/Concatenate
and there is answer in section "Concatenation of files with different codecs"
But I can't use it (neither with text file with videos nor with single-line command).
Does anybody had the same problem?
