Hi folks,
due to my ceiling at home i had to place my camera (Logitech c925) upside down in front of my TV. The picture i receive with Hyperion is consequently also upside down. Does anybody got an idea how to rotate the recorded picture?
v4l2-ctl --set-ctrl=rotate=180didnt work. "unknown control 'rotate'
If there is no sensible way to rotate, maybe there is a unknown function in Hyperion or a clever trick to do so with other Hyperion functions.
Thanks to you all 
Ah nice, they might be right! However, now i got another error message which confuses me 
Nope, still the same problem. I installed opencv and numpy to the up to date versions. You can check them in my screenshot.
that looks like some discrepancy in the versions of opencv or numpy. How did you install these?
for opencv i used the following
pip3 install opencv-pythonI did not install numpy yet. This might the cause of the problem
hanks for trying it out! This looks like an OpenCV library problem. Did you install it using `pip3 install opencv-python` or some other method? Tbh mine was cross-compiled on another host, so even pip3 install might not be sufficient.
Digging deeper into the error, looks like it complains about BLAS library - could you try the following?
Hey there, I tried you recommendations and used the troubleshoot from stewe93. However, i receive the following Error:
As I am relativly new to phyton programming i really hope you got an idea here.
Have a nice day, you did a great job
