[libcamera-devel] [PATCH 7/7] libcamera: formats: Map V4L2_PIX_FMT_JPEG to formats::MJPEG

[Jacopo Mondi]

The V4L2_PIX_FMT_JPEG and V4L2_PIX_FMT_MJPEG formats are under-specified
and are used interchangeably by kernel drivers.

Map both of them to formats::MJPEG and use the newly re-introduced
V4L2VideoDevice::toV4L2PixelFormat() to map to the one actually used by
the video device.
