playing with ubuntu touch on pinephone, and command line pictures.

Background.

default ubuntu touch image from the weekend;  not sure where to check the build number from within the image….

been running apt upgrade and update since then.  Plan is to update weekly the full image.

wifi and ssh seem to be working fine.

have media-ctl and ffmpeg running. (ffmpeg updated)

trying to get the best pictures possible;

found two setting that reliably work:

media-ctl -d /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:UYVY2X8/1920x1080]'
ffmpeg -hide_banner -f rawvideo -pixel_format yuv420p -s 1920x1080 -f video4linux2 -i /dev/video1 -vframes 1 -vsync 2 ~/Pictures/$(date +"%Y%m%dT%H%M%S").jpg

and

media-ctl -d /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:SBGGR8/1920x1080]'
ffmpeg -hide_banner -f rawvideo -pixel_format bayer_bggr8 -s 1920x1080 -f video4linux2 -i /dev/video1 -vframes 1 ~/Pictures/$(date +"%Y%m%dT%H%M%S")-bggr8.jpg

both seem very grainy, with different colours used;

looking now to see if can improve image;  Still looking at all the various flags;

the second seems to match (on my screen) the setting.

investigating:

• better colours
• can I access the auto focus
• clearer image
