libswscale - video scaling and pixel format conversion library
Contents
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.
• Pixelformatconversion: 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.
