To get information about the streams present in a file, use: We can even choose different options for each of these streams, but that’s enough for today already! We can choose to have more streams by adding more map options. Here, we explicitly select the streams 0 and 1 from the input file 0. Without specifying mapping options, the default behavior is to discover the “highest quality” single video input stream and “highest quality” single audio input stream from all input s, and “send” them to the output. Anyway, this has nothing to do with ffmpeg, it’s a shell thing. Beware though, having any whitespaces after the \ will turn it into a regular escape-sequence instead of line-continuation. Yes, you can split your command using the \ escape character. If you have different tracks, you can manually select the ones you want to end up in your output file using the map option: This provides good quality (maybe a little better?) but is very slow.
