FastCodec - free fast lossless video codec designed for video capture. The main design goals are simplicity and speed. Compression algorithm is relatively simple. The general scheme is:
  • Each frame is compressed separately.
  • Frame is divided into square blocks 4x4 or 8x4 pixels.
  • Every block converted from RGB to YUV color space.
  • Enumerative coding is applied to transformed block.
It seems that algorithm can be easily implemented in hardware. Compression and decompression operations requires low amount of memory - only for one image block.

  • Lossless and lossy compression.
  • Decompression in preview mode.
  • Frame size restrictions. Lossless compression requires that frame width and height must be a multiple of 4. Lossy compression requires that frame height is multiple of 4 but frame width is multiple of 8.
  • Supported input and output formats: YUY2/YUNV/V422/YUYV, YVYU, UYVY/Y422/UYNV, RGB24, RGB32.
  • Codec implemented as VFW driver, FOURCC is FCKK
