From b5f1adc8eee3163e1b6742c0e1f0c611a084193e Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 18 Dec 2008 15:45:00 +0100 Subject: video: add NV16 and NV61 pixel formats From: Magnus Damm This patch adds support for NV16 and NV61 pixel formats. These pixel formats use two planes; one for 8-bit Y values and one for interleaved 8-bit U and V values. NV16/NV61 formats are very similar to NV12/NV21 with the exception that NV16/NV61 are using the same number of lines for both planes. The difference between NV16 and NV61 is the U and V byte order. The fourcc values are extrapolated from the NV12/NV21 case.
