A presenter in BigBlueButton has the ability to share an external video with users in the live session.
The presenter role enables the assigned user the ability to share and control the video playback from an external video.
YouTube, Vimeo, Instructure Media, Twitch and Daily Motion URLs are supported links.
It is important to note the video playback will not appear in the processed recordings.
By default the first Moderator to enter the BigBlueButton session is allocated the presenter role capabilities; if you are a viewer you will need to request presenter status from the moderator.
When a user has the presenter role, the presenter icon will appear over their avatar in the users list.
Select the Actions menu  in the lower left hand corner of the presentation window, then choose Share YouTube video .
Copy paste an unlisted or public YouTube link into the Video URL  field and select Share a new video  to begin sharing.
The video playback will appear to all users of the session in the presentation area of the BigBlueButton interface; you can pause and skip through the playback.
It is important to note some mobile device browsers have auto playback of media turned off and the user will have to select play to engage the video playback.
Audio from the video will play on each users local system - no need to share an open audio source!
To Stop Sharing
Select the Actions menu  in the lower left hand corner of the presentation window, then choose Stop sharing video .
The previously displayed content will display in the presentation area.
