Overview

  • Compression of video stream is supported in the following formats:
  • RGB24, YUY2, YV12, RGB8 (this type is for the grayscale image compression).

Specifications

The codec's control is advanced with the following coptions:

  • 1. This option should be used for full-colored video in RGB-format (this option is ignored in YUV format video). This option should be switched off in video with less 16 colors.
  • 2. Interlace effect on video. Allows increasing compression ratio on interlaced video and to decrease it on non-interlaced :)
  • 3. To use the prediction algorithm for full-colored video. It's no use turning on this function in video with less than 16 colors.
  • 4. To use algorithms versions, optimized with SIMD-extension SSE. (supported with processors Intel Pentium III, AMD Athlon XP and older) It allows increasing the speed of compression/decompression to 20-50%. The information about your processor is also screened here (including if it supports SSE).
