I am trying to test a multi track video with alternate language tracks over RTMP to Wowza as a proof of concept. Only two channels and one track is sent. Is there a way to make this work. Or can this software publish as mpeg-ts ?

I think you might be able to use the FFMPEG option to manually set it up for that.

Found some hints to multiple audio tracks here:
https://video.stackexchange.com/questions/21734/ffmpeg-video-conversion-with-multiple-audio-tracks

I honestly don't know enough about it to find the exact commands you'd need, I'd actually like to find a way of doing this my self.

vMix only does 1 video and 1 (L + R) audio track. Even though FFMPEG does support multi-channel audio, vMix does not use that feature of FFMPEG..

it is possible in the streaming setting you can change the audio for ALL of the destinations, we usually send the 2-4 languages and in the master server split the audio using ffmpeg.

@ danrossi

Actually, vMix can send different audio busses to each stream destination.
(Master, Bus A and Bus B as selected in Stream Audio settings).
If your Video is multi-track however, you may not be able to playback alternate tracks as vMix only supports two channel stereo playback of video files.
