The invention discloses a real-time video plugin-free previewing method based on a RTSP and a real-time video plugin-free previewing
system based on the RTSP, the method comprises the following steps:acquiring a real-time code
stream from a front-end device; transmitting the real time code
stream of the front-end device to a streaming
media server through the RTSP; receiving and decoding the real-time code
stream in a H.264 format into an original code stream by the streaming
media server; by the streaming
media server, coding the original code stream into the code stream in a VP8 format, andforwarding the code stream in the VP8 format to each
client side browser; and by the
client side browser, decoding the code stream in the VP8 format through a
Web API based on a
WebRTC technology, and directly playing the decoded code stream through
HTML5. The
system comprises the front-end device, the streaming media
server and the
client side browsers. The method and the
system provided by theinvention have no need of installing plugins or extensions, support crossing browsers, also have no need of performing related setting operations of the browsers, and can preview no-
delay or low-delaymonitoring videos in real time.
