[FFmpeg-devel] [PATCH] Speex decoding via libspeex

This adds decode support for Speex using libspeex. Tested with talk109- 
q5.spx and speexaudio.flv

I'm not sure the best way to handle Speex in flv; there's no header  
packet, and the sample rate isn't set right in that sample. I could  
only find one reference that Flash uses wideband Speex, so I used the  
default values for wideband if there's no header, and it sounds okay.  
However, ffmpeg -i still prints out the wrong samplerate, I'm not sure  
the best way to fix that.
