ShufflePlanes
|
||
|
|
=============
|
||
|
|
|
||
|
|
.. function:: ShufflePlanes(vnode[] clips, int[] planes, int colorfamily)
|
||
|
|
:module: std
|
||
|
|
|
||
|
|
ShufflePlanes can extract and combine planes from different clips in the most
|
||
|
|
general way possible.
|
||
|
|
This is both good and bad, as there are almost no error checks.
|
||
|
|
|
||
|
|
Most of the returned clip's properties are implicitly determined from the
|
||
|
|
first clip given to *clips*.
|
||
|
|
|
||
|
|
The *clips* parameter takes between one and three clips for color families
|
||
|
|
with three planes. In this case clips=[A] is equivalent to clips=[A, A, A]
|
||
|
|
and clips=[A, B] is equivalent to clips=[A, B, B]. For the GRAY color
|
||
|
|
family, which has one plane, it takes exactly one clip.
|
||
|
|
|
||
|
|
The argument *planes* controls which of the input clips' planes to use.
|
||
|
|
Zero indexed. The first number refers to the first input clip, the second
|
||
|
|
number to the second clip, the third number to the third clip.
|
||
|
|
|
||
|
|
The only thing that needs to be specified is *colorfamily*, which controls which
|
||
|
|
color family (YUV, RGB, GRAY) the output clip will be.
|
||
|
|
Properties such as subsampling are determined from the relative size of the
|
||
|
|
given planes to combine.
|
||
|
|
|
||
|
|
ShufflePlanes accepts clips with variable format and dimensions only when
|
||
|
|
extracting a single plane.
|
||
|
|
|
||
|
|
Below are some examples of useful operations.
|
||
|
|
|
||
|
|
Extract plane with index X. X=0 will mean luma in a YUV clip and R in an RGB
|
||
|
|
clip. Likewise 1 will return the U and G channels, respectively::
|
||
|
|
|
||
|
|
ShufflePlanes(clips=clip, planes=X, colorfamily=vs.GRAY)
|
||
|
|
|
||
|
|
Swap U and V in a YUV clip::
|
||
|
|
|
||
|
|
ShufflePlanes(clips=clip, planes=[0, 2, 1], colorfamily=vs.YUV)
|
||
|
|
|
||
|
|
Merge 3 grayscale clips into a YUV clip::
|
||
|
|
|
||
|
|
ShufflePlanes(clips=[Yclip, Uclip, Vclip], planes=[0, 0, 0], colorfamily=vs.YUV)
|
||
|
|
|
||
|
|
Cast a YUV clip to RGB::
|
||
|
|
|
||
|
|
ShufflePlanes(clips=[YUVclip], planes=[0, 1, 2], colorfamily=vs.RGB)
