Hi,
I'm trying to convert a .mp4 file which contains 2 audio tracks to a
.mkv file, keeping the 2 tracks. I thought that using -map would be
enough, but clearly it isn't :

File 'toto.mkv' already exists. Overwrite ? [y/N] y
Output #0, matroska, to 'toto.mkv':

Stream #0.2: Subtitle: [0][0][0][0] / 0x0000, 64 kb/s
Codec type mismatch for mapping #0.2 -> #0.2
=================================================================
It seems it expects a subtitle track for the #0.2 output stream. I
didn't see how to change that. I tried to use the "-newaudio" parameter
but without any success.
My problem is also that my version of ffmpeg seems a bit outdated
compared to the online doc.
Thanks for any help.
