mediamtx
Use mediamtx on another Raspberry Pi to create RTSP camera stream for test.
Assuming you run mediamtx with Raspberry Pi CSI camera
and that raspberry-pi is the hostname of your device and that you expose two cams:
- CSI Rasberry Pi camera under /dev/video0
- USB camera under /dev/video1
so your mediamtx.yml has config fragment such as:
paths:
cam:
source: rpiCamera
endoscope:
runOnInit: ffmpeg -f v4l2 -pix_fmt mjpeg -video_size 1280x960 -framerate 30 -i /dev/video1 -c:v libx264 -preset ultrafast -b:v 6000k -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH
runOnInitRestart: yes
Start mediamtx server:
This should allow us to reach two streams, replace rpi-address with the name
of your Raspberry Pi hostname or IP address. The ports are default for mediamtx.
Or you could watch it via web browser under endpoints such as
Example with single camera over USB
Raspberry Pi Zero 2 + Logitech C920, thanks to user [&] undso.io for working example.
Allows to have a camera live stream and prusa camera script to use that stream as source of the images to send to PrusaConnect.

env file for prusa connect script, remember to replace [rpizero-ip] with
device address (or try 127.0.0.1 or 0.0.0.0 if script runs on the same host where mediamtx runs)
