I downloaded the current ffmpeg with git clone
git://source.ffmpeg.org/ffmpeg.git ffmpeg
The version of avcodec is 54.10.100

I built it but still get the same error message about
avcodec_alloc_context3() and  avcodec_open2().

Looking this up I read that "THIS FUNCTION IS NOT YET PART OF THE
PUBLIC API! we WILL change its arguments and name a few times!"

What am I missing?
