Raspberry pi camera v2 not working

Post by Taki741 »

Hello,

I ordered a raspberry pi camera v2 with the adafruit case for it. I have received it, but I’m having a problem with it. I ran a simple command, which was (sudo mplayer tv://). The camera should display live output to the screen. All I was getting was a blank screen with colored line all over it. As if there was a problem with the internals of the camera. I restarted the raspberry pi awell as unplugging and plugging the camera. It was still the same. Tried everything still nothing. I am certain it’s a defected camera.

Also the Adafruit Raspberry Pi camera Case with 1/4” Tripod Mount does not close as the camera is a bit bigger.

I paid extra for it to get here sooner, just my luck for it to not work. I have a project due in less than a week. Can someone please help, it really urgent.

It looks like you camera is communicating, but the encoding is wrong.

Try these command to confirm:

Code: Select all

v4l2-ctl -d /dev/video0 --list-formats-ext

Code: Select all

v4l2-ctl -d /dev/video0 -v pixelformat=H264 -V

Code: Select all

v4l2-ctl -d /dev/video0 --get-fmt-video

Code: Select all

mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=1920:height=1080:fps=30

Thank you for trying those commands and providing some shots of the output.

Are you running the Bullseye release of Pi OS? Have you enabled legacy mode in raspi-conf?

Before you turn on legacy mode you can try some of the libcamera commands.

Code: Select all

 libcamera-vid -t 10000 -o test.h264

Code: Select all

 libcamera-still --datetime

Im using the latest version of Raspbian Buster. I have used the Arducam and it worked fine. When I use a usb webcam it also works perfectly fine aswell. Searched up all kind of commands and tested it. The camera turns on, but no image only distortion and colored line. Tried to work with the resolution still no difference. I pretty sure this camera is most likely defective.

Okay we can try a replacement. My concern is that you were running Bullseye (current) which breaks all legacy commands due to libcamera unless Legacy mode is enabled.

Go ahead and request a replacement from [email protected] they will need your order# and this forum thread as authorization.
