[libcamera-devel] [PATCH v3 07/30] libcamera: formats: Support V4L2 non-contiguous formats
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Tue Sep 7 00:56:13 CEST 2021
V4L2 describes multi-planar formats with different 4CCs depending on
whether or not the planes are stored contiguously in memory. Support
this when translating between PixelFormat and V4L2PixelFormat.
