things to do for snow:
* multiple reference frames support
+number of picture buffers field per keyframe
+decode frame buffer index (into which decoding happens)
+display frame buffer index (which frame is outputed)
+a symbol per block to select the reference frame
+some changes to the motion estimation code
+some changes to the mv prediction code
* non translational motion compensation
+estimate non translational parameters per block by using surrounding
motion vectors
+add a ac coded bit per block to switch between translational and non
translational MC
+borrow the non translational MC code from libmpcodecs/vf_perspective.c
+some changes to the encoder to decide between translational and non t.
* trellis quantization (select quantized coefficient so as to minimize
the ratedistrortion
* 4x4 sized block support (we have 16x16 and 8x8 currently)
* 1/8 pel motion compensation / estimation support (pretty much just
encoder changes needed which in case of the iterative me should be
trivial)
* 1 pass ratecontrol

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
