[libcamera-devel] libcamera on pinephone

[Rafael Diniz]

So, here is the report of stock libcamera on the PinePhone:

- sun6i-csi with Sebastian patches:
. 
https://github.com/rafael2k/pine64-kernel/blob/maemo/beowulf-devel/debian/patches/maemo/0245-sun6i-csi-Implement-framesize-and-frameinterva.patch
. 
https://github.com/rafael2k/pine64-kernel/blob/maemo/beowulf-devel/debian/patches/maemo/0246-sun6i-csi-Limit-formats-to-those-compatible-wi.patch

- OV5640 with Jacopo branch.

- GC2145 still need some love... I'm using Sebastian patch:
. 
https://github.com/rafael2k/pine64-kernel/blob/maemo/beowulf-devel/debian/patches/maemo/0247-gc2145-Add-PIXEL_RATE-HBLANK-and-VBLANK-contro.patch

Using "cam" works with both cameras, in SBGGR8 format- OV5640 and GC2145 
cammeras. But with qcam, I could not get front camera (GC2145) get clear 
pictures, some funny "small-box" artifacts, but OV5640 works fine.

In Maemo-Leste (Debian 10 based) I use (as suggested by Pavel and using 
"-platform xcb" for Maemo / Debian 10):
qcam -r gles -spixelformat=SBGGR8,width=1280,height=720 -platform xcb

High resolutions, as Pavel mentioned, is fucked up for some reason. 
Colorspace conversion is not working also in qcam (I don't even know if 
color space conversion should be automatic).

Anyway, cheers! I can get some pictures already!
: )
