   Why do you want to do that ?

  I want to implement H264 Codec over dsp. And I think that I only need H264 Decoder in libavcodec.
  Is this idea not right ?or where is improper?Please give me some advices.

  thanks

   The decoder has never worked, and is way outdated, its code won't
  compil anymore.
   I have prefered to submit patch to ffmpeg and their decoder works
  pretty well except no B frame support (and maybe no interlaced
  cabac/calvc(?) support) and very slow.
   If you plan to work on a h264 decoder it would be really cool if you do
  on the ffmpeg one :)

   I think it has been fixed (it was a problem with block smaller than 8x8
  and cabac).
