Wirecast Rendezvous & WebRTC

Very simply put, when two people are having a conversation on Zoom – the browsers are talking DIRECTLY to each other: no encode, decode, player or anything. This also limits the number of people that can be on the call (I think 100 is about tops). You can take and WEBCAST a zoom session, and the people talking in the zoom session will be […]
High CPU Load on Wirecast – Maintaining Audio Sync
One of the biggest challenges in live webcasting is maintaining good audio sync. The best way to do that is keep CPU load down.
