Mux has released a simulcasting feature for live streams that enables users to broadcast simultaneously to multiple third-party platforms while also streaming from Mux. This feature is also known as "Live Syndication," "Rebroadcasting," and "RTMP Passthrough." The most common platforms people are simulcasting to include YouTube Live, Facebook Live, Twitch, and Periscope. To use this feature, users need to find their RTMP credentials, which consist of a server URL and a stream key. Mux recommends using the following settings for encoder configuration: 4,000 kbps at 720p resolution with 2s keyframe intervals, 30fps, and H.264/AAC video/audio codecs.
