QuickTime Broadcaster is media streaming software produced by Apple Inc. for Mac OS X. The software is an audio and video RTP/RTSP server. It is separate from Apple's QuickTime Streaming Server, as it is not a service daemon but a desktop application. It is able to stream live video and audio over a network in any QuickTime supported streaming codec.
Most QuickTime software was functionally defunct as of the release of macOS Catalina in 2019, with most functionality replaced by AVFoundation.
