NAME

libswscale - video scaling and pixel format conversion library 

DESCRIPTION

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

Specifically, this library performs the following conversions:

*
Rescaling: is the process of changing the video size. Severalrescaling options and algorithms are available. This is usually alossy process.
*
Pixel format conversion: is the process of converting the imageformat and colorspace of the image, for example from planar YUV420P toRGB24 packed. It also handles packing conversion, that is convertsfrom packed layout (all pixels belonging to distinct planesinterleaved in the same buffer), to planar layout (all samplesbelonging to the same plane stored in a dedicated buffer or ``plane'').

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