screensharetype=1replaces the webcam screen with the screen share
screensharetype=2creates a totally new connection for the screen share
screensharetype=3reuses the existing connection, adding a second video track; also doesn't show the local screen share window
screensharetype=3become the standard for sharing screens eventually, but for now it will remain optional, until the issues are all worked out.
&screensharetype=3screen share, you can now use
:sis appended to the end of the stream ID. This tells the system to ignore the webcam/mic feed, and just send over the screen share. You can do
&view=xxxx,xxxx:sto target both webcam and screen share though. I may change this syntax over time, but for now it works. The solo-links in the director's room has this
:sapplied already where needed.
