That's the aim of the Multimedia Wiki. As you say, it's currently  
mainly a drop box for snippets of information but as we add more to  
it, it could well grow into (and I believe it has always been Mike's  
intention that this be the case) _the_ online reference for video  
coding. :) At the moment I'm adding a few things about MPEG codecs  
slowly with pretty diagrams and throughout LinuxTag will be writing  
about/coding AMR. :D

See you later. ;)
