there is a related thread w tools to collaborate - adding-a-live-remote-feed-with-obs-ninja
The easiest way to do this in my mind - is to set up a separate encoding machine - to receive dj/vj sources in obs - and encode/stream.
Then each user has machine for vdmx/dj set up.
but this depends on equip availability. It seems the cheapest option to set up an encoding machines is to use nvidia 1660 hardware encode w obs.
- for a/v sync you would want to send the audio to the machine running vdmx - then out to the web. normal rtmp delay is about 20 seconds so makes tight av sync not possible.
otherwise it think vnc/screenshareing would be easiest to set up but would cause performance hit on vdmx machine.
there is this open source osc-web project. that … i dont have concrete suggestion how to integrate it but its out there.
there are also paid cloud based solutions - I’ve been working on project that uses this https://golightstream.com/studio/. Though It doe req that your live stream is re encoded … which means the quality goes down. think combining streams locally would be better.
