There is only one (minor) problem when compiling mplayer with shared libavcodec.
The ffmpeg doesn't install dsputil.h file, but mplayer spp filter(s)
make direct use of it.
I had always wondered what is the right solution: adding dsputil.h to install or
disabling spp filter(s).

I don't like either of them, so it would be nice to hear what do you think.
