Cannot kill picam #185
Comments
|
Does it happen 100% of the time (is it always reproducible)? |
|
Hallo, I was trying to make several videos one after another withe the length of 1 hour. It looks like after restarting the RPi, the first video is fine, but the second video stops after 10 minutes. And then the picam freeze and I need to restart the device. I am using RPi's original HQ camera and external USB soundcard Miditech Audiolink light. |
|
I don't have the HQ camera or Miditech Audiolink light, but if picam outputs the warning "Record buffer is starving", I think the camera stops working for some reason. Be aware that the camera is very sensitive to electrical interference, such as static noise, which can cause the camera to stop working. Please see if both |

Today I run a lot of test videos. I record and upload to youtube 7pcs of 1hour videos succesfully. During recording the 8th video at around 20 minutes into the recording the "Record buffer starving" starts to occure. I kill the picam and it stuck in state. I run And also Sidenote: As for the HW setup, camera is connected via 2m long camera cable, but it is in the old church with little interference. Prevouse version of SW run for almost two years without any problems. The problems starts when I update the SW with a fresh instalation of rasbian and a new picam. |

I think there is a hardware problem in your environment. Replacing the 2m cable with a shorter one, as you commented before, would help. #150 (comment) If you think it is a software problem, can you run |

This was a different church, I have arround 10 instalation in my country in different churches. In the one mentioned in #150, the RPi and camera was located on the pipe organs with the electric relays. This caused a lot of troubles from the day I install that RPi. After some time we moved the RPi far from the organs and it start to work. In different church with exactly the same HW and SW as in #150 this setup work without issues. Until I update the SW as I mentioned earlier. In this church the whole setup is located at the "noise-free" place far from the source of interference. For two years there was no problems with the setup. Until I update the whole setup :( *Footnote: To be sure I have the same setup in all of my 10 churches, I save SD card image and copy that image to all of my installations. I only change the credentials. As for the |
|
I see. Maybe the change in the camera stack (from OpenMAX to libcamera) is causing the problem. Please check if the device error only occurs when using picam. If the problem persists, you may continue to use the old version of picam. |

Hallo, I changed the camera cable for the shorter one (from 2m to 0.5m) and it now works for a week without any problems. Sorry for the troubles and thank you for your advices. If you have a spare time, can you try to introduce some interferances to your picam ribbon cable and try to repeat my issue? It would be great if the picam cannot stuck in state after some interferences and can carry on the transmition. And lastly, thank you for the excellent work with this project and your ongoing support :) |

@bostiko Good to hear that the problem has been resolved. |

Hallo, After several months of service (3-5 streams with 1 hour each per week) device stops working reliably. Now approximatelly 95% of streams stops before sheduled end with a log message "warning: Record buffer is starving. Recorded file may not start from keyframe. Try reducing the value of --gopsize.". Event more, approximately 50% of streams stops within first 5 minutes :( I tried several versions of picam from 2.0.5 to 2.0.12, but the situation is the same. The version 2.0.5 works on 4 other site without any problems. For about a week I am trying to resolve problem remotely, but I am not able to solve this. I have two questions:
Thank you :) |
Hallo,
sorry to bother you again. I have problem with one of my setup - usb sound card, HQ camera, picam and ffmpeg streaming to youtube.
At the prevously working instalaltion I made an update with the fresh install of raspian with latest picam. When I run streaming, the picam shows
warning: Record buffer is starving. Recorded file may not start from keyframe. Try reducing the value of --gopsize.after some minutes. When I try to restart the picam, the picam got stuck in state. I cannot end the picam even withpkill -9 picam.Can you help me, please?
