=head1 DESCRIPTION
|
||
|
|
|
||
|
|
|
||
|
|
The libswscale library performs highly optimized image scaling and
|
||
|
|
colorspace and pixel format conversion operations.
|
||
|
|
|
||
|
|
Specifically, this library performs the following conversions:

I<Rescaling>: is the process of changing the video size. Several
|
||
|
|
rescaling options and algorithms are available. This is usually a
|
||
|
|
lossy process.

I<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.
