Camera is right there, but the code didn't pick up the camera.

devices = device_provider.get_devices() in ./python/gstcaps.py gives error.

lida2003 · 2024-06-13T07:25:29Z

It seems something to do with camera firmware.

@stephendade Is it possible to use libcamera instead of gst for RTP/RTSP etc?

something like: "libcamera-vid -t 0 -n --inline -o - | gst-launch-1.0 fdsrc fd=0 ! h264parse ! rtph264pay ! udpsink host=192.168.235.166 port=5600"

it works fine with OV5647.

Maybe, there is an advanced option for user to select "gstream/libcamera"?

stephendade · 2024-06-13T07:42:45Z

Thanks for the report. This is a strange one - I've not seen it occur before.

I should have time to investigate next week.

lida2003 · 2024-06-13T08:14:48Z

Yeah. It's weird. Add some points which you can consider:

IMX219 - Raspberry Pi V2.1 has the same issue on my Raspberry Pi //I have some OV5647 with different EFL/FOV parameters
I have installed bullseys 64bit on Rasbperry Pi3B+
The camera will be recognized occasionally, after I upgraded the system 1 or 2 weeks ago.

lida2003 · 2024-06-16T06:26:22Z

It might be something to do with gst library, check below links:

And I have sucessfully found the camera with following binary commands:

unicam (platform:3f801000.csi):/dev/video0
ov5647

$ sudo v4l2-ctl --list-devices

I've had a look at this, running a RPi 3B+, OV5647, Bullseye x64.

I've been unable to replicate your issue - I can consistently detect the camera.

Whay version of Gstreamer and libcamera are you running:
gst-launch-1.0 --version I'm running 1.18.4
libcamera-hello --version I'm running v0.0.5+83-bde9b04f
pip show picamera2 I'm running 0.3.12
pip show PyGObject I'm running 3.38.0

lida2003 · 2024-06-26T01:32:35Z

No big difference, just picamera2 0.3.18

--- EDIT I reinstall picamera2 0.3.12, OV5647 comes back :). Will you please install picamera2 0.3.18 and try if it behaves as i did.

--- EDIT I reinstall picamera2 0.3.12, OV5647 comes back :). Will you please install picamera2 0.3.18 and try if it behaves as i did.

Yep, confirmed. Tried a few other versions. picamera > 0.3.14 has the issue.

EDIT: I suspect it's something to do with libcamera needing to be updated too. Stepping through the ./python/gstcaps.py code shows picamera2 trying to call some non-existant libcamera functions

EDIT: I suspect it's something to do with libcamera needing to be updated too. Stepping through the ./python/gstcaps.py code shows picamera2 trying to call some non-existant libcamera functions

Is it possible to trace the code (call stack), maybe we can fire an issue for libcamera or picamera2

--- EDIT: I got gdb segfault, and can't trace the call stack. Not sure how to handle this.

$ sudo apt-get install gdb python3-dbg
$ sudo apt-get install --reinstall python3
$ gdb python3

stephendade · 2024-06-27T01:09:40Z

The way I do is via code fragments. Here's a simple PoC based on ./python/gstcaps.py:

from picamera2 import Picamera2
print(Picamera2.global_camera_info())

Gives the following exception (when using picamera2 > 0.3.14):

File "/home/pi/.local/lib/python3.9/site-packages/picamera2/__init__.py", line 9, in <module>
    from .picamera2 import Picamera2, Preview

[BUG] ImportError: cannot import name 'Orientation' from 'libcamera' (/usr/lib/python3/dist-packages/libcamera/init.py) #939

Maybe we have to face the fact that there are difference between bookworm and bullseye.
And write an install script to distinguish the OS version and install proper picamera2 version?

stephendade · 2024-06-27T02:30:47Z

Using sudo apt install python3-picamera2 python3-libcamera will install the correct version for your OS. That's what I'm usng in ./deploy/RasPi2-3-4-5-deploy.sh

pip install method is not recommended.

lida2003 · 2024-06-27T02:50:05Z

OK. Maybe I have used pip upgrade before. Thanks for the support.
