How to share screen without enabling webcam?

[burakkaraceylan]

Hello,

It seems when we _rtcEngine.EnableVideo() the webcam stream starts. However I only want to share my screen and not enable webcam. Is this possible? _rtcEngine.EnableLocalVideo(false) is not working. I only want to share desktop screen and don't want to activate the webcam at all.

Can anyone help me? Because this problem leads to awkward situations like when a user is selecting which tab or window she would like to share her webcam feed is shown to all other users.

hi @burakkaraceylan , actually you can do this with a small code change.
You will want to use the ChannelMediaOptions to disable video publish when joining the channel. See API

public int JoinChannel(string token, string channelId, string info, uint uid, ChannelMediaOptions options)

Now, there is a small bug that will make you unable to enable the publishVideo option in the next run. You will need to make a small change in clientmanager.js, in the resetclient() function:

resetClient() {
    this.is_screensharing = false; // set to default
    this.videoSubscribing = true; 
    this.audioSubscribing = true; 
    this.videoPublishing = false;
    this.audioPublishing = true;
    localTracks.audioMixingTrack = null;
  }

The bug fix above will be put into dev/refactor8 and merge back to main when ready. But you can start doing that in your project before the release.
