  3. libswscale - video scaling and pixel format conversion library

  7.  
  8. The libswscale library performs highly optimized image scaling and
  9. colorspace and pixel format conversion operations.
  10.  
  11. Specifically, this library performs the following conversions:

  19. I<Rescaling>: is the process of changing the video size. Several
  20. rescaling options and algorithms are available. This is usually a
  21. lossy process.

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