NAME

6       libswscale - video scaling and pixel format conversion library
7

DESCRIPTION

9       The libswscale library performs highly optimized image scaling and
10       colorspace and pixel format conversion operations.
11
12       Specifically, this library performs the following conversions:
13
14       •   Rescaling: is the process of changing the video size. Several
15           rescaling options and algorithms are available. This is usually a
16           lossy process.
17
18       •   Pixel format conversion: is the process of converting the image
19           format and colorspace of the image, for example from planar YUV420P
20           to RGB24 packed. It also handles packing conversion, that is
21           converts from packed layout (all pixels belonging to distinct
22           planes interleaved in the same buffer), to planar layout (all
23           samples belonging to the same plane stored in a dedicated buffer or
24           "plane").
25
26           This is usually a lossy process in case the source and destination
27           colorspaces differ.
