IMPORT DETAILS

Based on ffmpeg svn r22886 dated 15 April 2010.

The decoder is a heavily modified version of the original ffmpeg floating point
implementation. It's been modified to use fixed point arithmetic and now plays
and seeks on all the targets that Rockbox supports. Currently only supports mono
and stereo streams, streams with more than 2 channels are not yet supported.
