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. 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.
