Raspberry Pi Camera

[babourn]

Any updates on support for using CSI camera's for capture within balena? I saw that Nvidia docker now supports it

Work is ongoing in the pi-cam branch, with testing using the jetson-nano and jetson-nano-2gb-devkit device types. See changes in the launch.sh file.

Currently, we are still experiencing the following errors when using VIDEO_INPUT = raspberrycam:

Hi @alanb128,

Just thought I'd check-in on if you have made any headway locally, or if we're in a limbo until Nvidia offers additional support in the subsequent L4T release?

Thanks!

hello any update on this? when can we support csi camera? does balena docker itself able to support CSI camera? i got an error says cannot generate outputstream whenever I tried to read my csi camera. haven't found any solution online.
