Does Ultragrid support multiple streams on the same machine?

Hi there,

Does Ultragrid support sending and receiving AV data to and from more than one other device? For example one pc to communicate at the same time with 2 other pcs, sending and receiving AV data to and from them?

Otherwise, is broadcasting possible?
If yes, may I ask how?

Thank you so much,

using the reflector you can take a single stream and send it to multiple recievers.

Thank you, Alan! Would you mind elaborating a bit? Maybe with a command. This is the first time I hear about reflector.
BTW, do you know where I can find more info about each command? I read the pdf from janet and I also know how to use the help command, but the info I sometimes get is not really understandable. :/

Thank you so much!

You can start with this page. I am just not completely sure from the original post if it is what you need? Reflectors can be used for 1-to-N transmissions (usually unidirectional broadcast). If you need only 2 (or more) P2P transmissions from within one computer, then just use a separate port number (the -P parameter) for different streams (default UG port is UDP/5004 for video and UDP/5006 audio). Just remember that there should be at least offset of 4 between the parameters given to -P.

To sum up, Alan's answer is completely correct - the reflector can be used for one stream to more recipients. Using different ports can be used for multiple streams with more peers (perhaps bidirectional), also a difference is whether you want to use one capture device for all or a different one for any peer.
