|
|
|
<p>The libswscale library performs highly optimized image scaling and
|
|
colorspace and pixel format conversion operations.
|
|
</p>
|
|
<p>Specifically, this library performs the following conversions:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
<em>Rescaling</em>: is the process of changing the video size. Several
|
|
rescaling options and algorithms are available. This is usually a
|
|
lossy process.
|
|
|
|
</li><li>
|
|
<em>Pixel format conversion</em>: 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").
|
|
|
|
<p>This is usually a lossy process in case the source and destination
|
|
colorspaces differ.
|
|
