As in the subject, when I run:
sudo uvccapture -S40 -C30 -G80 -B20 -x1280 -y720 -v
I get a big black picture (same result with -m flag)
BUT, when I ran:
sudo uvccapture -S40 -C30 -G80 -B20 -x1280 -y720 -v -t5
This means that he will take a picture every 5 seconds.
It works well (photo is ok).
But I can’t use this command because it won’t stop taking pictures.
Do you know what might be wrong?
result:
