I have BananaPi M3 with its ov8865 camera module. I test its camera capture by the code: https://github.com/avafinger/cap-v4l2
It works fine when using “video mode” as the following command:
./cap 1920 1080 8 1 -999 -1 -1
I can get a normal picture captured by camera.
But it fails when I test “image mode”. Its command is
./cap 1920 1080 8 0 -999 -1 -1
I get a abnormal picture(it is dark, and looks like auto-exposure not working)
Is the driver vfe_v4l2.ko not ready for image mode?
