The idea is to develop a cross-platform, standalone application that could play a video, streamed over RTSP, using HTML5 or JavaScript or any other web technology.
回答1:
RTSP is a protocol on the same level as HTTP. Its impossible to do RTSP via HTTP.
The HTML5 video tag could support RTSP but no browser implements it.
It may be possible to create an RTSP proxy using websockets but that wouldn't be true rtsp any more. And it would mean, all the demuxing and protocol stuff had to be implemented in JS which would be quite inefficient.
I think your best alternative would be using either HTTP streaming with the video tag or WebRTC.
