Questions about features

Is it possible to broadcast to multiple devices?

Yes. However, the more devices being transmitted to, the greater the burden on the transmitting device. For example, on a new desktop PC it's possible to transmit 720p video to about 5 devices, but anything more than that will require using an SFU broadcast server.

Is simulcast supported?

Currently, version 1.0 does not support simulcast.

Can you broadcast the feed from multiple cameras?

Currently, version 1.0 cannot.

How do you increase the video quality?

Video quality depends on the quality of the network.

Is Realtime-Raytracing supported?
