Hi Nick, not sure which command is "cam --list" is it a argument for "snapshot"?
anyway i ran this, apparently there are cam devices detected: *$ v4l2-ctl --list-devicesipu6 (PCI:0000:00:05.0): /dev/video0 /dev/video1* *[...]/dev/video31 /dev/media0Web Camera - HD: Web Camera - H (usb-0000:00:14.0-6): /dev/video32 /dev/video33 /dev/media1* But the command says that there was no sensor found for /dev/media0: $ snapshot [...] [0:07:26.712925495] [8023] INFO Camera camera_manager.cpp:327 libcamera v0.4.0 *[0:07:26.722742733] [8059] INFO SimplePipeline simple.cpp:1581 No sensor found for /dev/media0* Strangely, camera is indeed showed when running he command as root (even whith the same "*No sensor found for /dev/media0"* message so perhaps this is not related with the error). In this case, after a few seconds the app crashes with a segfault.
