Only two channels and one track is sent. Is there a way to make this work. Or can this software publish as mpeg-ts ?

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.

Even though FFMPEG does support multi-channel audio, vMix does not use that feature of FFMPEG..

(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. Ice
