FastCodec

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.

Specifications:

• 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

Output Files: AVI
