+The Smoke Codec
+---------------
+
+This is a very simple compression algorithm I was toying with when doing a
+Java based player. Decoding a JPEG in Java has acceptable speed so this codec
+tries to exploit that feature. The algorithm first compares the last and the 
+new image and finds all 16x16 blocks that have a squared difference bigger than
+a configurable threshold. Then all these blocks are compressed into an NxM JPEG.
+The quality of the JPEG is inversely proportional to the number of blocks, this
+way, the picture quality degrades with heavy motion scenes but the bitrate stays
+more or less constant.
+Decoding decompresses the JPEG and then updates the old picture with the new
+blocks.

+TODO:
+----
+- make format extensible
+- motion vectors
+- do some real bitrate control
