15 The libswscale library performs highly optimized image scaling and
|
yading@10
|
16 colorspace and pixel format conversion operations.

|
yading@10
|
18 Specifically, this library performs the following conversions:

22 @emph{Rescaling}: is the process of changing the video size. Several
|
yading@10
|
23 rescaling options and algorithms are available. This is usually a
|
yading@10
|
24 lossy process.

27 @emph{Pixel format conversion}: is the process of converting the image
|
yading@10
|
28 format and colorspace of the image, for example from planar YUV420P to
|
yading@10
|
29 RGB24 packed. It also handles packing conversion, that is converts
|
yading@10
|
30 from packed layout (all pixels belonging to distinct planes
|
yading@10
|
31 interleaved in the same buffer), to planar layout (all samples
|
yading@10
|
32 belonging to the same plane stored in a dedicated buffer or "plane").
|
yading@10
|
33
|
yading@10
|
34 This is usually a lossy process in case the source and destination
|
yading@10
|
35 colorspaces differ.
