Ok, thanks - although I believe it will be a quite lengthy and cumbersome
process, as xbmc currently is based on ffmpeg version 0.10.2 ;-) What do
you say about regression testing the binary way and start somewhere in the
middle. What version do you suggest we start with?

Agreed, it would be nice to clean up and use only the necessary flags. I
suspect many of the settings are a legacy from the old 0.10.2 days.
