[libcamera-devel] [PATCH 14/13] apps: qcam: Add option to configure sensor

[Kieran Bingham]

Add a '-f|--sensor_format' option to qcam to allow forcing a sensor
configuration from the command line.

As an example:
qcam -f width=3840,height=2160,bitDepth=10

Extending Jacopo's implementation for cam to qcam
Helpful for testing with visual display of the selected modes.
