Add video to a conversation
Remove video from a conversation
Subscribe to changes from the videoService in a conversation
Accept video without sending video
With an existing conversation instance, video can be added or removed.
Add video to a conversation
conversation.videoService.start().then(function () {
// Successfully added video to the conversation
// Set the video window container
conversation.selfParticipant.video.channels(0).container(document.getElementById("renderWindow"));
channel.isStarted.set(true);
});
You may also set the video window container prior to starting the videoService.
// Set the video window container
conversation.selfParticipant.video.channels(0).container(document.getElementById("renderWindow"));
conversation.videoService.start().then(function () {
// Successfully added video to the conversation
conversation.selfParticipant.video.channels(0).isStarted.set(true);
});
Note
Setting the video container more than one time for the same video stream will cause problems with video playback.
Remove video from a conversation
Conversation.videoService.stop().then(function () {
// Successfully removed video from the conversation
});
Video can also be removed by stopping the audioService.
Conversation.audioService.stop().then(function () {
// Successfully removed audio and video from the conversation
});
Subscribe to changes from the videoService in a conversation
An event is fired when the client has successfully added video to the conversation, or another participant has invited the client to add video.
- Subscribe to the event.
conversation.selfParticipant.video.state.changed(function (val) {
…
});
- If the val argument in the previous snippet indicates the event is an invitation to add video, the client may reject or accept the invitation.
if (val == 'Notified') {
if (confirm('Accept incoming video request?')) {
console.log('accepting the incoming video request');
conversation.videoService.accept();
console.log('Accepting incoming video request');
}
else {
console.log('declining the incoming video request');
conversation.videoService.reject();
}
}
Accept video without sending video
Clients can accept requests for video without sending their own video by calling audioService.accept().
- Subscribe to the video state changed event.
conversation.selfParticipant.video.state.changed(function (val) {
…
});
- If the val argument in the previous snippet indicates the event is an invitation to add video, the client may accept the invitation without sending the client's video.
if (val == 'Notified') {
conversation.audioService.accept();
}
- The client's video can be added later.
conversation.selfParticipant.video.channels(0).isStarted(true);
