2024/08/30 20:13:18 ERR [path front] [RPI Camera source] fork/exec /dev/shm/mediamtx-rpicamera-1725063198554484679/mtxrpicam: no such file or directory

Describe how to replicate the issue

Raspberry Pi4 w/ Raspberry Pi OS (Bookworm). I added the Pi Camera per the docs and it fails to find it.

front:
source: rpiCamera

I'm not using legacy camera interface, vcgencmd get_camera returns :
supported=0 detected=0, libcamera interfaces=0

rpicam-hello finds it and returns:

Did you attach a network dump?

no

Also experiencing this issue on pi zero 2w.

this happens because you are using the 32-bit operative system and the 64-bit server. Use the same architecture on both the operating system and server, as explicitly mentioned in the README.

[nathan-stewart]

It's not so explicit in the README. It simply says "both are supported". While it should be obvious to use the one that matches the OS, since Dec 2023 Raspberry Pi Os ships with a 64 bit kernel even when installed 32 bit, and uname reports aarch64 in both cases. Even if the user is aware of that, it's not clear which the app needs (ie if it says aarch64 you'd naturally want to suggest one built aarch64.)

I’m interested in this ticket. I downloaded bookworm 64 bit on a raspberry pi 5 with the pi camera 3.When I installed medianmtx 1.9.0 armv864 and I update the medianmtx.yml to use rpiSource with basic settings I get this error also.I’m at work but once I get home I can upload logs if that’s not considered hijacking this thread.Sent from my phoneOn Sep 3, 2024, at 5:50 AM, nathan-stewart ***@***.***> wrote: It's not so explicit in the README.
