Data pusher means that RTSP server receives external data sources and then sends them out as RTSP streams.
The data pusher support TCP, UDP and RTSP mode.
Audio and video data are packaged and sent in RTP format.
If you use TCP or UDP mode data push, you need to add <pusher> tag in the rtsp server configuration file, specify the push audio and video parameters and push port, etc.
If you use RTSP mode to push data, no configuration is required. The url suffix of the pushed RTSP address can be any legal string.
If it is RTSP mode, it supports standard RTSP push stream, such as FFMPEG rtsp pusher.

FFMPEG rtsp over UDP:
ffmpeg -re -i test.mp4 -vcodec libx264 -acodec copy -preset ultrafast -f rtsp rtsp://yourip/pusher

FFMPEG rtsp over TCP:
ffmpeg -re -i test.mp4 -vcodec libx264 -acodec copy -preset ultrafast -f rtsp -rtsp_transport tcp rtsp://yourip/pusher

The key of RTSP over HTTP is to allow RTSP packets to communicate via HTTP port.
We know that the 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

First establish an HTTP connection, and then upgrade to the websocket protocol,RTSP over websocket protocol upgrade process:

C-->S:
GET /websocket HTTP/1.1
Host: 192.168.3.27
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Key: KSO+hOFs1q5SkEnx8bvp6w==
Origin: http://192.168.3.27
Sec-WebSocket-Protocol: rtsp.onvif.org
Sec-WebSocket-Version: 13

S-->C:
HTTP/1.1 101 Switching Protocols
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Accept: G/cEt4HtsYEnP0MnSVkKRk459gM=
Sec-WebSocket-Protocol: rtsp.onvif.org
Sec-WebSocket-Version: 13

After the protocol upgrade is successful, perform standard rtsp protocol exchange, and send and receive data through websocket connection.

RTSP server source code is written in C/C++ language
Support Windows platform
Support Linux / UNIX platform
Support Android platform
Support iOS / MAC platform
Support embedded platforms

Happytime RTSP Server's sole purpose is to help you host a server on your computer that allows you to broadcast various multimedia streams. Running the executable automatically starts the server and provides you with brief instructions on how to play a stream from an external location.
This application features support for various audio and video documents, camera device, live screen and audio device. Therefore, you are provided with multiple possibilities regarding file compatibility. However, the files you want to access via streaming need to be in the same directory as the server executable.

The demo version supports up to 4 concurrent streams.
The release version supports up to 100 concurrent streams
