[Ffmpeg-devel] problem with avcodec_find_decoder

[Daniel Dantas]

Hi,
   
  I got the latest SVN version of ffmpeg, and i'm having trouble with 
  avcodec_find_decoder(CodecID id) function.
   
  I'm newbie in this subject so probably i'm gonna make some stupid question.
   
  I'm trying to decode and H264 coded file, and the function avcodec_find_decoder returns null when the argument is CODEC_ID_H264. 
   
  The same happens with CODEC_ID_MPEG4, when trying to decode mpeg4.
   
  Some other formats doesn't work too, while others works well...
   
  I don't know what is happening, i think maybe i have to say to the compiler the codecs i want when building the dll's(I'm using VS 2005). 
   
  Or maybe it has to do with some configure comand...
   
  How can i make these codec's avaiable ???
   
  Please help me!!
  Thanks
  Daniel
