Is there a way to change video output just like setAudioSource?

[meljason]

In the documentation I see that to change the audio source, there is setAudioSource. But for changing the camera, the only option available is cycleVideo.

However, I have a select dropdown option with the list of cameras I got with OT.getDevices. How do we change the camera using something like setAudioSource?

I am using javascript and I tried to get a workaround this by unpublishing the publisher and "restarting" the stream by initialiazing the publisher again.

So here it is:

videoSelectOption.addEventListener("change", () => {  
            var optionSelect = videoSelectOption.options[videoSelectOption.selectedIndex].id;

            session.unpublish(publisher);
            restartStream();

            // Create a publisher
            function restartStream() {
                publisher.destroy();
                publisher = OT.initPublisher(
                    "subscriber",
                    {
                        insertMode: "append",
                        style: { buttonDisplayMode: "off", nameDisplayMode: "on" },
                        width: "100%",
                        height: "100%",
                        name: displayUser(),
                        videoSource: optionSelect
                    }, err => {
                        if (err) {
                            alert("Publish error " + err.message);
                        }
                    }
                );
                session.publish(publisher);
            }
        })   

So basically, what I did here is stopping the publisher and reinitializing it. But the problem with this is it destroy the stream then comes back again which will make the user leave the session and join again. Is there a way to change the camera without having to leave the session? Something just like setAudioSource.

Hi, currently it's not possible to setVideoSource as you would do it with the audio source. The only way, as you said, is to use cycleCamera or unpublish/publish .

Is the unpublish/publish solution the best solution? So there is no other way to change the camera without actually unpublishing right? Which means that the user will have to leave the session and rejoin when the camera changes.

It depends on your use case. If you know that your users are going to have <=2 webcams most of the time, cycleVideo is fine.

Otherwise, the unpublishing approach is the way to go for now.

I see! Thank you for your reply. Really helped!

We released setVideoSource API on the 2.19 JS SDK https://tokbox.com/developer/sdks/js/reference/Publisher.html#setVideoSource
