webcam settings

[ghost]

Hi,
How can i change camera settings like resolution, exposure, brightness ? Is it possible ?

[theyosh]

Euh... not yet. Resolution will be added. Other options not. I work with auto balances and wait for 2 seconds to let the camera auto adjust. Then I take an image of the webcam.

A rpi-cam has always the same resolution. And external does not need to know it, it can read it out from the source.

Update with git pull. Restart and clear browser cache. That should give you the new resolution options

So, i will close this issue now. I will not make other webcam settings for now. To much variation with different types of webcams.

Ok,
Sorry for my late answer, thanks for adding resolution settings. I tried to change settings directly with v4l2 -ctl but it change nothing. Images are over-exposed.

Thanks again for your work

I can do this: https://unix.stackexchange.com/questions/412214/how-to-manage-the-white-balance-in-webcam

And it will change my USB webcam color settings and white balance. Disable auto balance setting to get your own settings working. As mentioned in the post

[theyosh]

Or other trick. Use it on your laptop and see if the camera will work correctly. Use tools to adjust the white balance. When happy, disconnect from laptop and use it on the PI.

It could be that this will somehow the webcam to work better with auto white balance or other settings
