RTSP over HTTP and HTTPS
The key of RTSP over HTTP is to allow RTSP packets to communicate via HTTP port. Standard port of RTSP is 554, but due to various security policy configurations such as firewalls, there may be restrictions when the client accesses port 554, which prevents the normal transmission of RTSP packets. But the HTTP port (port 80) is generally open, so there is the idea of letting RTSP packets pass through port 80, namely RTSP over HTTP.
RTSP over Websocket
WebSocket protocol basically provides bidirectional communication between Client and Server for web application. This describes how a WebSocket connection can be established between a client and a server.
Example from ITVStreamer Geek Log print: WebSocket Handshake
This example shows the message transfer between an Web client (client) and an Web server (server). The client requests server to initiate a WebSocket connection using the WebSocket URI. The WebSocket Uri can be retrieved using the GetServiceCapabilities command of the ONVIF Media2 Service. An example WebSocketURI may look like, “ws:/ /192.168.88.1/webSocketServer”
GET /websocket HTTP/1.1
HTTP/1.1 101 Switching Protocols
After the protocol upgrade is successful, perform standard RTSP protocol exchange, and send and receive data through websocket connection.
Hadware acceleration decoding
Hardware acceleration is a method of speeding up computer processing by shifting work to a computer part that can do the job faster. Hardware acceleration for ITVStreamer generally refers to using your GPU graphics card for better performance. See GPU decoding.
