camera rotation #16

Closed mdinata closed 3 years ago

mdinata commented 3 years ago

First, thanks for simplifying the process and awesome tutorial on youtube. It works in Pi0W without any problems. I use Pi0 case which position the case in the up-right to get the picture in the right orientation. Physical camera rotation is not possible considering how the camera module is fitted in the case. Would u please share how to rotate the camera orientation from configuration so i can put the camera sideways (USB cable from below).

Thank you

I believe adding this line to the file /uvc-gadget/piwebcam just after the other v4l-ctl control options should rotate the picture 90 degrees

/usr/bin/v4l2-ctl -c rotate=90

@trek2710 - If that option works—I wonder if setting rotate=0 would be a good default (so people searching the code for rotate would at least find it and be able to change it to 90, 180, etc.)?

aejrussin commented 3 years ago

The issue is that the user won't know what the rotation is until they plug it in. Are there any edits they can make to the config file?

The option does work, BTW.

I'd vote for including this option somehow in the installation process (either by clearly documenting it or by making it configurable in the playbook). I have a Zero W in the official case and I had exactly this issue. In an ideal world, the camera would notice its own orientation, but that doesn't work in an environment without orientation sensor.
