From fbcb2dc3519ac09068e09ef8c1de35e006de29ec Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 2 Mar 2014 06:43:12 -0300 Subject: [media] media DocBook: fix NV16M description The NV16M description contained some copy-and-paste text from NV12M, suggesting that this format is a 4:2:0 format when it really is a 4:2:2 format. Fixed the text.

The three components are separated into two sub-images or planes. V4L2_PIX_FMT_NV16M differs from V4L2_PIX_FMT_NV16 in that the two planes are non-contiguous in memory, i.e. the chroma -plane does not necessarily immediately follows the luma plane. +plane does not necessarily immediately follow the luma plane. The luminance data occupies the first plane. The Y plane has one byte per pixel. In the second plane there is chrominance data with alternating chroma samples. The CbCr plane is the same width and height, in bytes, as the Y plane. -Each CbCr pair belongs to four pixels. For example, +Each CbCr pair belongs to two pixels. For example, Cb0/Cr0 belongs to -Y'00, Y'01, -Y'10, Y'11. +Y'00, Y'01. V4L2_PIX_FMT_NV61M is the same as V4L2_PIX_FMT_NV16M except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr byte. -- cgit v1.2.1
