Raspberry Pi NoIR相机挂起

Question

Background Information:

I built a smart door solution with a RPi B+ (Raspbian) which makes use of three sensors (PIR, Gyroscope [I2C] and an Ultrasound). Depending on the sensor status managed by a Python script, I start recording a video by using the raspivid command and/or play sounds on Bluetooth speakers. I also have a USB WIFI dongle connected to the RPi.

This is how I call the Pi NoIR camera in my .sh file:

raspivid -w 800 -h 600 -t 15000 -o file.h264 -n -rot 270

Problem description:

The camera works fine for a while (I cannot precise for how long [2 hours maybe] nor what triggers the issue), but then it stops working. The funny thing is that I get no error message.

What did I do to identify the root cause:

• I tried to manually kill the child process (Raspivid) but it simply doesn't work. If I kill the parent process (.sh file) then my child process gets assigned to the PID 1 (init.d).

• I tried recording a new video in a new terminal window but the new process hangs too.

• Rebooting the Pi doesn't work neither. It says it is rebooting but it does not (not even with the -f option).

• I installed a new Pi Camera ensuring it was not a hardware or ribbon problem.

• Camera has enough memory available.

• Pi has enough power (Red led is always on)

• -v returns no error

• I have installed V4L2-CTL but I have the same issue

How can I get it fixed? Thanks!

Answer 1

By looking at your kernel messages, specifically the line containing '__vb2_queue_cancel', I think your problem may partially be related to Raspberry's kernel drivers. Have you checked if your kernel contains the fix given at [1]? If not, applying that oneliner may fix your problem.

For some reason your camera application is stopping video capture and due to the aformentioned bug it fails to do so. This may at least give you a chance to restart your capture pipeline.
