yading@10: 
yading@10: The libswscale library performs highly optimized image scaling and
yading@10: colorspace and pixel format conversion operations.
yading@10: 
yading@10: Specifically, this library performs the following conversions:
yading@10: 
yading@10: @itemize
yading@10: @item
yading@10: @emph{Rescaling}: is the process of changing the video size. Several
yading@10: rescaling options and algorithms are available. This is usually a
yading@10: lossy process.
yading@10: 
yading@10: @item
yading@10: @emph{Pixel format conversion}: is the process of converting the image
yading@10: format and colorspace of the image, for example from planar YUV420P to
yading@10: RGB24 packed. It also handles packing conversion, that is converts
yading@10: from packed layout (all pixels belonging to distinct planes
yading@10: interleaved in the same buffer), to planar layout (all samples
yading@10: belonging to the same plane stored in a dedicated buffer or "plane").
yading@10: 
yading@10: This is usually a lossy process in case the source and destination
yading@10: colorspaces differ.
