NAME
       libswscale - video scaling and pixel format conversion library

DESCRIPTION
       The libswscale library performs highly optimized	image scaling and
       colorspace and pixel format conversion operations.

       Specifically, this library performs the following conversions:

       o   Rescaling: is the process of	changing the video size. Several
	   rescaling options and algorithms are	available. This	is usually a
	   lossy process.

       o   Pixel format	conversion: is the process of converting the image
	   format and colorspace of the	image, for example from	planar YUV420P
	   to RGB24 packed. It also handles packing conversion,	that is
	   converts from packed	layout (all pixels belonging to	distinct
	   planes interleaved in the same buffer), to planar layout (all
	   samples belonging to	the same plane stored in a dedicated buffer or
	   "plane").

	   This	is usually a lossy process in case the source and destination
	   colorspaces differ.
