Re: [FFmpeg-user] Re-encoding mkv files from makemkv
Pehache, Thank you for this simple explanation/reminder: > Reminder : by default ffmpeg keeps only 1 video track and 1 audio > track (so here you are implicitely dropping the second audio track and > the subtitle track). "-map 0" means that you keep all the tracks > present in the input file. "-map 0:0 -map 0:2 -map 0:3" means that you > want to kepp the video track, the second audio track, and the subtitle > track. When digging through the archives for guidance this kind of advice, however simple it may seem, is gold. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

That is an awfully old build of ffmpeg. I would upgrade before fiddling much. I have experienced problems with old builds of ffmpeg and transcoding mkv files. From memory: the ffmpeg process would eat up all available memory on the server and then crash. Sometimes, the error message would be like the one you reported, sometimes the out-of-memory daemon would kill it. IIRC, upgrading to a newer build of ffmpeg fixed the problem for me.
