This project originally came from https://github.com/beihuijie/carrier-rtsp-server.
It's a very spartan RTSP server, using the live555 library for RTSP implementation, and a FIFO file descriptor to feed the H.264 frames from the SDK example. It's not robust, but it works.
This repo differs by making it work with lower memory devices using the T20L variant, like the Xiaofang 1S. I have reverse-engineered the 1S binary in the firmware, and found undocumented SDK calls to increase the pool sizes in order to allow the SDK to function under low memory.
The IR LEDs are now also software-controlled via PWM channel 0. The settings were also reversed from the 1S binary, and should work with the WyzeCam v2 since they also got rid of the CdS photoresistor.
Also, you can find more technical information from the original Dafang Hacks project.
-
Download the T20 toolchain, either from the Dafang-Hacks GitHub repo or the Tuya GitHub repo.
-
Set up the
PATHenvironment variable to add the toolchain directory. -
Clone this repo
-
Run the
makecommand. You should end up with thet20-rtspdbinary in the directory.
