[Mesa-dev] [PATCH 09/14] st/va/postproc: add a full NV12 deint support from buffer I to P

[Leo Liu]

Before it's impossible to transcode an interlaced video, becasue if
in order for encoder to work, we have to force buffer to progessive,
but the deint with buffer from I to P is missing. Now along With
the new YUV deint full function, it works with weave and bob deint.

Also this will benefit transcoding video with scaling parameters.
