Hi,
Some troubles with a camera module 2.1 (not-noir) on a Raspbian buster,
version 2019-09-26 on a pi4 b, with motion 4.1.1
Taking image snapshots with raspistill and raspivid works beautifully, day
and night. Exposure is proper, contrast is high. Also the
mjpeg-streamer-experimental (also mmal-aware) does the same.
Now I'm trying to capture the camera directly in motion.
It is functional, but the images produced are of poor quality. Washed out,
grey for blacks in low light yet most of the screen white in sunlight.
I tried setting mmalcam_control_params -ex auto -op 255 -sh 0 -co 0 -br 50
which is what raspistill appears to be doing, but the result is still a lot
worse. Other combinations of these settings are worse still.
All hints/ideas are most welcome.
Thanks in advance,
Joris

You don't have to use port forwarding. If you only have one external site
accessing the video, you could push it out using an ssh reverse tunnel.
