video: add NV16 and NV61 pixel formats
PATCH 1/1 video: add NV16 and NV61 pixel formats
From: Magnus Damm <[email protected]>
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.
