Livedesk Studio lets you broadcast on any video streaming service from your Mac. You can use it with any platform, like Youtube Live, Facebook Live, Livestream, UStream, etc.
Livedesk Studio connects to any media live streaming platform that supports the RTMP, RTMPS or RTMPT protocols, AAC audio and H264 video codecs. Basically, all streaming platforms will support this configuration (the service must provide you the stream URL and the name).
