Like this audio 1 = englisch rtp://xxxxxx
audio 2 = german rtp://xxxxxx

and so on. Our someone know a Software that can do this.
best regards

do U need multiple output streams ? video + each individual audio ?

only Audio each Channel (mono) one rtp stream

so .. https://trac.ffmpeg.org/wiki/How%20to%2 ... p%20option

yes i know this option but it only works with files not with live input (Blackmagic Card)

why not with input ?

For example, assuming INPUT is a stereo audio file, you can switch the two audio channels with the following command:
ffmpeg -i INPUT -map_channel 0.0.1 -map_channel 0.0.0 OUTPUT


if you want to mute the first channel and keep the second:
ffmpeg -i INPUT -map_channel -1 -map_channel 0.0.1 OUTPUT
