       libswscale - video scaling and pixel format conversion library


       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

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