Please keep that in mind if mkvmerge aborts with an error message regarding invalid '-append-to' options.Įrror: The track number 0 from the file '2.mp4' cannot be appended to the track number 0 from the file '1.mkv'. A default mapping of 1:0:0:0,1:1:0:1 will be used instead. No append mapping was given for the file no.

Mkvmerge v19.0.0 ('Brave Captain') 64-bit I cannot concatenate two videos because of different video codecs: $ mkvmerge -o merged.mkv 1.mkv \+ 2.mp4 I would like to use ffmpeg, mencoder or still something free.
