The camera should automatically set the exposure the next time you start the stream.
I was just about to open this issue. The outside photo is unusable due to over exposure. It is almost white only. Then with raspistill
command I get expected nice photo. These work just fine.
raspistill -ex auto -o exauto.jpg
raspistill -o default.jpg
Actually, the issue affects also darkness. Then hkcam might produce almost black photo while with raspistill
you get some quite dark photo but still something that can be expected from this kind of camera.
With hkcam both exposure issues can be seen in Apple Home and Home 3 even with snapshots.
If I set auto exposure to 0 (automatic mode) via v4l2-ctl --set-ctrl auto_exposure=0
, the exposure is updated while streaming.
It was like that already for me. Setting it again didn't make a difference.
$ v4l2-ctl --get-ctrl auto_exposure
auto_exposure: 0
$ v4l2-ctl --set-ctrl auto_exposure=0
Things look good inside, but if I point the camera out the window everything gets blown out. Is there auto exposure?
