Camera board • Picamera3 not streaming

Hi,

I'm running a headless RPi5 and a Picamera3 wide noir connected to it. I wrote a python script based on this https://github.com/raspberrypi/picamera ... erver_2.py example that was streaming my camera so that I can view stream through a browser. Since recently my streaming stopped working. I could open the page, but there was no video showing up.

Here are my troubleshooting steps:

• Running the vanilla example from above. Copy-paste and run - no output. Opening the page in a browser does not show anything, and the browser never finishes loading. I couldn't find any errors on RPi.

• Tried capturing a single image with rpicam-jpeg, and this works fine. It captures the image okay:

  Code:

  rpicam-jpeg -r -md 4 -o test2.jpeg

• Tried capturing a video into a file with rpicam-vid, and this works fine. It captures the video okay:

  Code:

  rpicam-vid -t 5sec -o test.mp4

• Tried streaming a video with rpicam-vid, and viewing it through VLC player (over the network). It did not work, I just see black VLC screen. Also, no errors on RPi.

  Code:

  rpicam-vid -t 5sec -o test.mp4

For some of these tests I also turned on DEBUG logging through the env variable LIBCAMERA_LOG_LEVELS="DEBUG". Didn't reveal anything unusual.

I recently did an update of RPi, so I'm not sure whether that might have caused to stop it from working?

Has anyone got any ideas what might be the issue here? I'm not sure what to do because I don't see any errors, it's just that over network nothing works, while locally it does.

Thanks
