mmal (buffer header callback not defined) #10
Comments
Raspberry Pi 4B I get inconsistent performance from Raspistill and using the PiCamera module to take photos, with the same error; mmal: mmal_port_event_send: event lost on port 1,0 (buffer header callback not defined) The Pi fails to save pictures around 40% of the time. The other 60% it states the error, but still saves the photo correctly. Hopefully this gets addressed as the camera functionality is core for many Pi users. |
HI, I'm facing the same issue. Raspberry 4 B output is the same as @openbsod shared - except I have:

ov5647 simply indicates Camera Module v1 https://www.raspberrypi.org/documentation/hardware/camera/README.md |
Hi, Creating jpg image with "rasptstill" command always fail, Also, creating image with following python script, displays same error message: But this time the correct image file is always created. from picamera import PiCamera
from time import sleep
camera = PiCamera()
camera.rotation = 180
camera.capture('/home/pi/Desktop/image.jpg') +) Added |
I found the other helpful link.
At the bottom of the page it says:
Who manages this Raspberry-Pi-OS-64bit github page? |
Any news on this? |
