This example works for esp32 ai thinker dev kit.
The project is built with platform.io and vscode.
git clone https://github.com/daton89/esp32_cam_rtsp.git
Rename the file with wifi credentials running cp include/wifikeys_example.h include/wifikeys.h and replace the informations with your data.
Now flash the device:
pio run -t upload # (This command will fetch dependencies, build the project and install it on the board via USB)
To check that everything is working and to get the ip address of the device open the serial monitor:
pio serial monitor
To see the camera from the browser:
open http://192.168.0.19 # replace with camera ip from serial monitor
To see the RTSP stream using VLC:
vlc -v rtsp://192.168.0.19:8554/mjpeg/1
