@item planes
Set which planes will be processed, unprocessed planes will be copied.
By default value 0xf, all planes will be processed.
@item inplace
Do not require 2nd input for processing, instead use alpha plane from input stream.

for RGB formats bit 0 is green, bit 1 is blue and bit 2 is red;
for YUV formats bit 0 is luma, bit 1 is chroma-U and bit 2 is chroma-V.
If present, the alpha channel is always the last bit.
