I’ve just taken a trial of the Wowza WebRTC feature within the Wowza Streaming Engine, it looks like a great beginning from you guys, congratulations!

I’ve seen this question asked before, but around compositing / PIP (picture in picture) / mosaics :-

- Are we able to record the meeting through Wowza as a single output, rather than on a per stream basis?

- Unless I use a transcoder (and even then, only 320p was actually outputting anything, the others remained empty), I cannot record streams themselves directly, is this a known bug / shortcoming?

- Has anyone ever managed to composite multiple streams of this kind (or any RTP source) into a single output back out to Wowza Streaming Cloud? Even if via a ffmpeg / gstreamer proxy?

Many thanks

Mark
