The input code is pretty simple; for v4l you just
read(fd,buf,framesize); it should be quite simple to read input from a
PNM or similar.

I've looked over the code for this also -- though the wavelet
transform is currently over my head (though I hope to remedy that
soon; any resources to suggest?), I do notice that it's reading the
entire video into one big buffer and passing the entire buffer to the
wavelet transform. Obviously this won't work for streaming; the
wavelet has to break somewhere. Perhaps a windowed wavelet?

And how about getting a bitstream for this? It should be easy enough
to encapsulate the results of the wavelet transform in an Ogg stream.
