[PATCH] video: add NV16 and NV61 pixel formats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Magnus Damm <damm@xxxxxxxxxx>

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.
