Looking to get a data buffer in memory of post mixer output so it can be muxed into a video stream. What’s the best approach to take here? Am I looking at a custom output plugin or is there another/better approach to take? Thanks

It depends largely on if you want to hear the audio or not. If you do, then I recommend a custom DSP plugin attached to the master channel group to capture the audio. If you don’t want to hear it and perhaps want to process faster than realtime, a custom output plugin would be ideal.

Thanks Mathew, I think the custom DSP solution sounds like a better path.
