Several +rescaling options and algorithms are available. This is usually a +lossy process. + +@item +@emph{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. +@end itemize + +@c man end DESCRIPTION + +@chapter See Also + +@ifhtml +@url{ffmpeg.html,ffmpeg}, @url{ffplay.html,ffplay}, @url{ffprobe.html,ffprobe}, @url{ffserver.html,ffserver}, +@url{ffmpeg-scaler.html,ffmpeg-scaler}, +@url{libavutil.html,libavutil} +@end ifhtml + +@ifnothtml +ffmpeg(1), ffplay(1), ffprobe(1), ffserver(1), +ffmpeg-scaler(1), +libavutil(3) +@end ifnothtml + +@include authors.texi + +@ignore + +@setfilename libswscale +@settitle video scaling and pixel format conversion library + +@end ignore + +@bye |
