  • What is lib Swscale used for by ffmpeg programers?
    • http://stackoverflow.com/questions/3367187/what-is-lib-swscale-used-for-by-ffmpeg-programers
      - Swscale is mainly used for players, not encoding/decoding
      - at a different pixel size/aspect ratio,  colorspace conversion between various RGB and YUV color formats
      - no faster software implementation presently exists for any of them, at least on x86 and x86_64
