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:
- •
-
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.
