* Available resolutions can be taken from the #GstCameraBin:video-source-caps
* property. Image capture resolution can be set with
* #GstCameraBin::set-image-resolution action signal.
*
* Some video source elements implement the #GstPhotography interface, which contains
* functions and properties for setting photography parameters. One can use
* gst_bin_iterate_all_by_interface() to get a reference to it.
