[libcamera-devel] [PATCH v2 4/8] libcamera: pipeline: uvcvideo: Translate from V4L2 to DRM pixel formats

[Niklas Söderlund]

When generating a camera configuration pixel formats directly from the
video device are used that contains V4L2 pixel formats. Translate the
pixel formats to DRM before using them i the camera configuration.
