What is RTSP?
RTSP is short for Real-Time Streaming Protocol. It is a protocol for transferring real-time data from multimedia to an endpoint device. RTSP creates and controls the media stream as a network remote control and communicates directly with the server streaming the data.
RTSP does not stream the media (audio and video) itself, but it will tell the streaming server to do the actions as the user commands. For example, when a viewer pauses the live video, the RTSP protocol will convey this request to the streaming server and complete it. The most typical commands are pause, play, and record.
A quick overview of the RTSP Protocol
- Audio Codecs: AAC, AAC-LC, HE-AAC+ v1 & v2, MP3, Speex, Opus, Vorbis
- Video Codecs: H.265, H.264, VP9, VP8
- Benefits: Low-latency, IP cameras streaming
- Drawbacks: No longer a common protocol, is not optimized for viewing experience and scalability
- Latency: 2 seconds
- Variant Formats: The entire stack of RTP, RTCP (Real-Time Control Protocol), and RTSP is often referred to as RTSP
