This is my own algorithm. Actually there are two: one is a byte-based algorithm that is very fast and the other is bit-based (like DST) that is slower but compresses better (and still uses less CPU than DST). If I had to make a rough estimation of the average compression ratios, it would be about 0.6 for the fast mode, 0.5 for the high mode, and 0.4 for DST. -David _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
