looks like ffmpeg have changed their API again - you could try
downloading an older version of ffmpeg and compile against that - you
may need to make some minor changes to the rb-browser Makefile to make
sure it finds your downloaded ffmpeg rather than the system one

I'll have a look at the new API and see how much pain it is going to be
to convert rb-browser to use it - I may end up packaging a known version
of ffmpeg with rb-browser as this is not the first time this type of
thing has happened with ffmpeg...
