Black Screen Issue with go2rtc on Raspberry Pi 4 #1252

Closed Rhox21 closed 2 months ago

Rhox21 commented 3 months ago

I am experiencing issues with go2rtc on my Raspberry Pi 4. I am running go2rtc version 1.9.4 and using it for an OctoPrint web stream. After an unspecified amount of time, I only get a black screen and have to stop and restart go2rtc via the terminal. This is particularly annoying as I am trying to film time-lapses, and the stream failure disrupts this process. After a failure, the configuration tab is sometimes empty.

Here is my current configuration code:


streams:
   picam_mjpeg: exec:libcamera-vid -t 0  --autofocus-range normal --autofocus-window 0.25,0.25,0.5,0.5 --width 2592 --height 1944 --codec mjpeg --libav-format mpegts -o - --vflip

// log:
    // level: trace

ffmpeg:
  bin: /home/swex/bin/ffmpeg-6.1-amd64-static/ffmpeg

Could you provide some guidance on how to resolve this issue?

Thank you.

Edit: Octoprint runs in docker but the screen from go2rtc webinterface is also black 🤷

You need to collect logs and stream info at the moment of problem.

What happened? The issue has recurred. When I remove the print from the printers bed and my hand is visible in the image, the picture suddenly freezes in OctoPrint. This occurs frequently after removing a completed print from the bed. Refreshing OctoPrint UI in the browser only shows a black image. After restarting via the Go2RTC interface, OctoPrint displays an error message "Webstream not loaded".

Observations: After restarting via the Go2RTC GUI, the following logfile with one error is generated:

Current Workaround: To get the camera running again, I had to restart using the terminal commands stop go2rctc and start go2rctc. After this, the camera works again in OctoPrint.

Suspected Cause: The logs suspected that the camera is being claimed by another service. Running sudo lsof /dev/video0 and sudo kill PID restores the stream also in OctoPrint.

Webcam works after restarting Go2RTC or using corresponding terminal commands grafik

TLDR: The issue occurs when the hand is visible in the image after removing a print from the bed, causing the image to freeze in OctoPrint and resulting in webcam failure. The camera is likely being claimed by another service, temporarily resolved by restarting Go2RTC or using corresponding terminal commands.

I would like to determine whether the issue lies with Go2RTC or another program that may be monopolizing the camera. Any assistance would be appreciated because manually restarting is soo annoying.

The Error came again just after i started a print and my hand was in the image. Over the night it was stable. This is the log when the error occurs:

Currently 7 streams but i dont have image in stream. grafik

@AlexxIT Issue can be closed. Found the problem: i removed the autofocus option from the config file.
