[libcamera-devel] libcamera on pinephone

[Rafael Diniz]

This an image I just took with the PinePhone at home with (the OV5640 cam):
qcam -r gles -spixelformat=SBGGR8,width=1280,height=720 -platform xcb

https://www.abradig.org.br/maemo-crazyness/back_camera-qcam-2.jpg

There are some strange artifacts... what are those?

Cheers,
Rafael
