If you want to broadcast your camera along with another person's camera on a live stream, it is possible! However, to get it working well, it will take some dedication to understand some of the finer points of video and audio inputs from your end.
You can easily broadcast a Zoom meeting to Uscreen as a Live Event via RTMP. Though, there are some drawbacks. You've probably noticed that Zoom's quality isn't the greatest for its audio and video. That's because Zoom is reducing the quality to save bandwidth costs, and it doesn't let you set it yourself.
Zoom is probably fine if you're having a chat with another person and want to stream that as a live event. However, if you want to get music involved or play media for your users to watch, it's not going to work. Zoom doesn't allow you to play a media file directly, and if you wanted to, you'd have to share your screen and sound to play the media, which can cause lagging and other issues. So the quality will not be good enough to show it to your viewers.
So, how do we make this work? One fantastic software is Wirecast Rendezvous. It's like creating your private Zoom call with the ability to change what you're broadcasting. You can easily chat with someone else in another city and then switch to play a film, broadcast different camera angles, or add music to it.
It's great, but it's not cheap. Wirecast's cheapest option is $599, which allows you to display up to two remote webcams. So you're limited to chatting with two friends/guests. However, if you're willing to take the time to invest, this can help you take your streaming to the next level!
