[libcamera-devel] [PATCH v2 0/3] V4L2Device Try format support

[Kieran Bingham]

Extend V4L2Device to provide a tryFormat function. This can be used to check a
format against a V4L2 Device to determine a suitable configuration.

Utilise this in the UVC pipeline handler so that we can validate configurations
on any UVC web cam.
