The libswscale library performs highly optimized image scaling and |
|
|
11 |
colorspace and pixel format conversion operations. |
|
|
12 |
|
|
|
13 |
Specifically, this library performs the following conversions: |

I: is the process of changing the video size. Several |
|
|
22 |
rescaling options and algorithms are available. This is usually a |
|
|
23 |
lossy process. |

I: is the process of converting the image |
|
|
29 |
format and colorspace of the image, for example from planar YUV420P to |
|
|
30 |
RGB24 packed. It also handles packing conversion, that is converts |
|
|
31 |
from packed layout (all pixels belonging to distinct planes |
|
|
32 |
interleaved in the same buffer), to planar layout (all samples |
|
|
33 |
belonging to the same plane stored in a dedicated buffer or "plane"). |
|
|
34 |
|
|
|
35 |
This is usually a lossy process in case the source and destination |
|
|
36 |
colorspaces differ. |
