ffmpeg | branch: master | Philip Langdale <philipl at overt.org> | Sun Nov 20 13:55:49 2016 -0800| [237421f14973a81fe342f7500db176e1c09c58f6] | committer: Philip Langdale

avutil: add P016 pixel format

P016 is the 16-bit variant of NV12 (planar luma, packed chroma), using
two bytes per component.

It may, and in fact is most likely to, be used in situations where
there are less than 16 bits of data. It is the responsibility of
the writer to zero out any unused LSBs.
