The BergWave package currently consists of three parts :
- libbw: the main video de-/encoding library
- test: a simple example programm
- vfw: video for windows interface
BergWave is working in yv12 colorspace. Color conversion functions where XviD taken from the XviD project, a open source MPEG 4 video codec (www.xvid.org).
At the moment BergWave doesn't support delta frames, but that's on the doto list. To compress the yv12 image BergWave uses 5,3 wavelet transform with run length encoding.
The values are coded by rice encoding. Every frame has n objects (wavelet image, motion vectors). The frame end is marked with a null object.
