Highly unreliable with freezes when using Pi 3B and Debian 11 #73

Open zocker-160 opened 2 years ago

zocker-160 commented 2 years ago

I hope someone can help me with this, because I am starting to get a bit desperate with this problem.

I am running an application for displaying a 2x2 or 3x3 grid displaying CCTV cameras which uses libvlc using python-vlc. When running on Pi 3 hardware and Debian 10, everything works, but since moved to Debian 11, I am struggling with major issues.

VLC is initialized like this

self.vlcInstance = vlc.Instance(
    "--vout=mmal_vout",
    "--no-xlib"
)

Pi3 is connected to a 720p TV and I have allocated 256MB of memory to the GPU. Everything either freezes just after a few seconds with sudo killall being the only option to close it or I get a segmentation fault, here are my logs:

Raspberry Pi 3B Kernel: Linux R1-PI 5.15.61-v7+ #1579 SMP Fri Aug 26 11:10:59 BST 2022 armv7l GNU/Linux Debian 11.5 python-vlc 3.0.16120 vlc 3.0.17.4-0+deb11u1+rpi1+rpt3

Any help would be highly appreciated!

EDIT: I want to add that at no point in time do I actually see any video playing, it is just black until freeze or crash. I can rule out a hardware defect, because it works fine on Debian 10 and also Pi 4B + Debian 11 works fine.

Can you just confirm you are running RPiOS bullseye? (I believe you are based on the kernel build number). Note: That there are actual debian images which are quite different and don't include this repo's version of vlc.

I installed the system using PI Imager, here is my os-release:
