I am not sure if this is the right thread to post this question, but I
want to do something similar for the Dirac video codec, i.e. add a
fourcc tag to the codec_bmp_tags struct. The reason for this being, I'd
like to wrap Dirac in AVI, and also be able to play back Dirac (raw
streams and  wrapped in AVI) using mplayer (the mplayer patch is in
development). I'd like to use a fourcc code 'drac' for Dirac. Does this
need to be officially registered somewhere or can I just add it to the
list?
