[WIP]: Screenshare

[m1k1o]

Adding screenshare support to neko.

Things to sort out before merging:

• Turn off video/audio pipeline and controls when screenshare is active. Turn it back on when it ends.
• See if data can be directly passed through or must be reencoded.
  • Add support for multiple codecs.
• Sometimes when starting and stopping screenshare multiple times it does not work - must be reliable.
• Create GUI.

First two screenshares works, thrid one does not.

Server:

ERR Incoming unhandled RTP ssrc(1661240182), OnTrack will not be fired. mid RTP Extensions required for Simulcast

Cleint:

Uncaught (in promise) DOMException: Answer tried to set recv when offer did not set send

What is the use case for this? I wonder if features like this can be included optionally during the build using 'feature flags' to avoid code bloat?

[m1k1o]

This feature is quite lightweight. If some user would like to share something quickly from their local screen. This use case is coming from collaborative space. For me its insteresting as PoC if that can be implemented nicely.

makes sense.

This would come in extremely useful for me as a potential replacement for broken screenshare solutions on other platforms that tend to break on Linux, hoping we'll see this implemented in the future!

For now, Screego exists.

Even though it's available on other projects, I would also love it if I can have it here.
I think there is a problem at renegotiation for add and removetrack

Instead of using add and removeTrack, wouldn't replaceTrack a better option, since we only want to have one videostream, and because of using replace we wont need renegotiation?

[m1k1o]

We actually need to send a video stream, not only receive on the sender side. On the receiver side, nothing should be changed as the shared screen is simply taked over the broadcasted video.
