Copyright (c) 2000-2012 the FFmpeg developers In all following examples, we will use an example input file like this one: # fmpeg -i input.mkvįfmpeg version. In case you want to control which streams are included, or include more than one stream in the output, then you will need to specify the '-map' command manually, and change these parameters. All other input streams are in essence discarded. The default behavior of ffmpeg is to choose the best video and audio stream in a file and drop the rest. This command will multiplex the video file video.mp4 and the two audio files into a new file: video.mxf Audio Streams Mapping

Multiplexing of three independent sources ffmpeg -analyzeduration 100M -probesize 100M -i video.mp4 -i left.wav -i right.wav -map 0 -map 1 -map 2 -c copy video.mxf In that case you should use some of the above mentioned methods to exclude the scrambled streams or -copyts. Please note that ffmpeg won't execute this command in case you have a stream which is scrambled. In some particular cases you should also. This command will copy everything on the input and insert it in the output without re-encoding it. Mapping of everything ffmpeg -i input.ts -map 0 -c copy output.ts This command will map to the output only programs with ID 1, 2, 3 and 4 to the output ts. This command will map only the streams with ID 0:1, 0:2, 0:3 and 0:4 to the output ts and will drop everything else Mapping of whole programs ffmpeg -i input.ts -map 0:p:1 -map 0:p:2 -map 0:p:3 -map 0:p:4 -c copy output.ts In case of some unsupported streams you would need to use the -ignore_unknown or -copy_unknown to either drop out or copy the unknown streams Specific Streams Mapping ffmpeg -i input.ts -map 0:1 -map 0:2 -map 0:3 -map 0:4 -c copyoutput.ts The output of this command will show you all the programs and streams available in the MPTS. This could be done using the following command: ffmpeg -i input.ts But first you need to check how many channels there are in the input file. So in case you have a MPTS ts file you will need either to define which particular streams you want to be processed to the output or which programs.
