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:

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

       •   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.
