I want to get the dynamic properties of camera like white balance, e
xposure, contrast etc. Is there any API that would get this for me?I know it can be done using v4l2src but I want some higher level API.
Not that I know of. I believe that after the kernel ioctl, you have a command line called v4l2-ctl. Note that on most cameras (uvc) these values are just firmware configuration. To get the per image applied metadata, you need to open and grab these using the second video device expose by recent kernel.
We don't yet have GStreamer support for that. The metadata will be in HW specific form and needs to be parsed. UVC has a shared format across cameras.
Overall, it seems something that should be abstracted by libcamera in the future.
