[OTHER] *OR BUG Picamera 0.3.19-1 hangs on easy_capture script while older versions work fine

monkeymademe commented 3 months ago

I don't want to claim this is a bug cause its not really giving much information

I updated my system today to the latest picamera2 (0.3.19-1) and libcamera v0.2.0+120-eb00c13d - suddenly my v3 cameras stopped working in my script when they worked before.

Its a script that starts a stream and it just hangs not even allowing keyboard interrupts. In an effort to see if my cameras are toast. I used the easy_capture script to see if it works.

This is the output from terminal

After this it just stopped... So I tried again with a v2 camera and got this

So it worked and I got my test.jpg where the other times in 0.3.19 i did not? Or is it the latest libcamera?...

monkeymademe commented 3 months ago

Also I am not sure if its something I am missing or did not do or should update?

davidplowman commented 3 months ago

Hi, I've just tried the following

from picamera2 import Picamera2
picam2 = Picamera2()
picam2.start_and_capture_file("test.jpg")

and it seemed OK. Can you fill me in on the details of your system. What kind of a Pi is it? How did you update it? Are you connected directly with a screen and keyboard or remotely, via ssh or vnc? Also, does rpicam-hello (and the other rpicam apps) work? You could also try downgrading picamera2 using pip (which will hide the apt version), though I would generally delete it after the experiment to avoid getting muddled about which one it's using.

Thanks!

monkeymademe commented 3 months ago

System:

Pi5 - Debian GNU/Linux 12 (bookworm) x2 tested on 2 systems one was already updated when I noticed the issue the other was working and then updated then it stopped working Picamera2 0.3.19-1 and libcamera v0.2.0+120-eb00c13d

Pi4 - Debian GNU/Linux 12 (bookworm) Picamera2 0.3.17-1 and libcamera v0.2.0+46-075b54d5

Update method:

sudo apt update

Connection - SSH from the report above but since you mentioned it I went back to the pi5 and ran the code on desktop the QTgiPreview window opens but no content is shown its blank.

The pi4 running the same code was over ssh and I got my test.jpg

davidplowman commented 3 months ago

I'm getting a bit confused here, are we saying your Pi 4 is working and your Pi 5 isn't?

Also note that the recommended update procedure is

sudo apt update
sudo apt full-upgrade

I've run this all again on a Pi 5 which works for me. I have Picamera2 0.3.19. rpicam-hello --version reports

rpicam-apps build: 49344f2a8d18 17-06-2024 (12:09:08)
libcamera build: v0.3.0+65-6ddd79b5

and the firmware version (vcgencmd version) is

2024/04/20 11:53:30 
Copyright (c) 2012 Broadcom
version d1744d21 (release) (embedded)

and the Linux kernel (uname -a)

Linux raspberrypi 6.6.31+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux

so those might all be worth checking.

monkeymademe commented 3 months ago

Oh man I am so sorry... Total pebcak moment here. sudo apt full-upgrade was the issue and fixed the problem half way. But yeah I did not run that before.

After the webcam UI I am working on is working again so YAY... BUT...

Running the easy_capture in terminal on desktop the QtGIPreview window opens but still no content and is just black and hangs there. In SSH : the output is

For now I guess its working enough for me to continue what I am doing but I don't know what the issue is with the black preview window (camera works fine otherwise)

davidplowman commented 3 months ago

Well, there's still something a bit weird going on there. If it's complaining about DRM, that means it thinks the desktop isn't running and that it's not connected via ssh. To be fair, figuring out how you're connected is actually quite tricky, so that can go wrong. It would certainly get confused if you use ssh but without -X (X-forwarding) and then try to display a preview window. So maybe just check what the Pi's $DISPLAY variable says once you've logged in. The rules are:

ssh without -X : you can't have a preview window.
ssh with -X : preview window should work, but you'll get a software rendered preview spamming your network with uncompressed video.

monkeymademe commented 3 months ago

Yeah checked export but display is not set... then for giggles I retested the easy_capture and it worked fine! Might have needed a reboot and a dodgy ssh connection... new computer and its not totally setup the way I like it yet.

Thank you so much for the support and sorry it was a silly one

davidplowman commented 3 months ago

No problem, good luck!!
