The other option of course is to use our codecs directly. You can compile the codeclib separately from Rockbox and call it directly from another program or using the command line. We provide most of the same formats as ffmpeg but all integer.

I talked to the ffmpeg people about it almost a decade ago. Since then floating point hardware has become very common and the need for fixed point diminished. The closest thing I can think of would be vlc for android which uses an early version of our fixed point decoder that is still closer to ffmpeg.
