Camera not showing in Live #9

Closed wyohman closed 4 months ago

wyohman commented 6 months ago

Brand new install on bookworm. I tested camera with libcamera-hello:

wyohman@raspberrypi:~ $ libcamera-hello [0:04:34.782090969] [873] INFO Camera camera_manager.cpp:284 libcamera v0.2.0+46-075b54d5 [0:04:34.954627653] [876] WARN RPiSdn sdn.cpp:39 Using legacy SDN tuning - please consider moving SDN inside rpi.denoise [0:04:34.960985705] [876] INFO RPI vc4.cpp:447 Registered camera /base/soc/i2c0mux/i2c@1/imx708@1a to Unicam device /dev/media0 and ISP device /dev/media1 [0:04:34.961190133] [876] INFO RPI pipeline_base.cpp:1144 Using configuration file '/usr/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml' Preview window unavailable Mode selection for 2304:1296:12:P SRGGB10_CSI2P,1536x864/0 - Score: 3400 SRGGB10_CSI2P,2304x1296/0 - Score: 1000 SRGGB10_CSI2P,4608x2592/0 - Score: 1900 Stream configuration adjusted [0:04:34.966523388] [873] INFO Camera camera.cpp:1183 configuring streams: (0) 2304x1296-YUV420 (1) 2304x1296-SBGGR10_CSI2P [0:04:34.967358705] [876] INFO RPI vc4.cpp:611 Sensor: /base/soc/i2c0mux/i2c@1/imx708@1a - Selected sensor format: 2304x1296-SBGGR10_1X10 - Selected unicam format: 2304x1296-pBAA

As well as libcamera-still -o test.jpg and the jpg looked very nice.

Updated config to start automatically and I was able to create a user and login. When Iogin I can see the right side options Focus, Zoom, etc.. but nothing on the Live side.

If I click Photo, Raw or Video, I see this message at the bottom (message shown for each button).

Error in Camera.takeImage: Phototaking caused error: [Errno 12] Cannot allocate memory Error in Camera.takeRawImage: Taking raw photo caused error: [Errno 12] Cannot allocate memory Error in Camera.takeImage: Phototaking caused error: [Errno 12] Cannot allocate memory

Feels like I must missing something but I went over the instructions multiple times.

Info shows what I would expect for my setup (RPI 3b+ and imx708_wide)

It seems you are using a Pi 3. Unfortunately, I havn't one myself for testing. My experience with Pi Zero and Pi 4 was that these systems had memory issues with the larger resolution of the new sensors and larger values for buffer_count. Also, these systems require "YUV420" format for the lowres stream.
Therefore, I set the default values for configuration settings accordingly.

Checking in my code, I just see that the buffer_count for Pi 3 is not set to a lower value of 2 as it is done for Pi Zero and Pi 4.

Can you check in the Config page for Live View which value for Buffer Count is set.
If the value is 6, set it to 2.
The settings for Pi 3 should probably be the same as for Pi 4:

... and for Video, Buffer Count should be 4.

I just staged version V2.3.6 where the settings should also apply for Pi 3.

You can update with
cd ~/prg/raspi-cam-srv git pull
sudo systemctl restart raspiCamSrv.service

WOW! Thanks for the info and update! I now see the live view and will be working on putting it in place for more testing.

Where can I donate to keep this going?
