Yes, I got this also. It seems to be a bug in the ffmpeg plugin.

I don't know if this is the correct solution, but I have a patch for 
this (against 0.4.6).

I have another problem regarding the MPEG layer 3 audio decoding. I 
cannot find any code for doing this in plugins/mpeg_adec, but layer 3 
audio is listed on the vlc web page. The only sound output is squeaking 
noises. Is layer 3 audio supported?
