Hi!
From: Dmitry Perchanov dmitry.perchanov@intel.com
[ Upstream commit a8f2cdd27d114ed6c3354a0e39502e6d56215804 ]
The formats added by this patch are:
V4L2_PIX_FMT_Y16IInterlaced lumina format primary use in RealSense Depth cameras with stereo stream for left and right image sensors.
This will add unneeded defines to -stable.
Best regards, Pavel

+Interleaved grey-scale image, e.g. from a stereo-pair
+Description +===========
+This is a grey-scale image with a depth of 16 bits per pixel, but with pixels +from 2 sources interleaved and unpacked. Each pixel is stored in a 16-bit word +in the little-endian order. The first pixel is from the left source.
+**Pixel unpacked representation.** +Left/Right pixels 16-bit unpacked - 16-bit for each interleaved pixel.
