This driver supports two different video formats: the first one is the "8-bit
Sequential Bayer" format and can be used to obtain uncompressed video data
from the device through the current I/O method, while the second one provides
-"raw" compressed video data (without frame headers not related to the
-compressed data). The compression quality may vary from 0 to 1 and can be
-selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2
-ioctl's. For maximum flexibility, both the default active video format and the
-default compression quality depend on how the image sensor being used is
-initialized (as described in the documentation of the API for the image sensors
-supplied by this driver).
