[MPlayer-users] Question about deleting external libraries dependencies

[Zongyao QU]

We built  mplayer with dependencies on external libraries before, 
but now we want to trim the size of the files as much as possible.
We thought  there may be some codecs duplicated with ffmpeg, 
so delete the external libraries are the best way AFAIK.

The libraries are 

libdca
libfaac
libfaad2
libfontconfig
libfreetype
libogg
libspeex
libtheora
libvorbis

But losing functionalities is unacceptable.

So the question is which of these libraries could be excluded,
 and the decoding abilities could be 
substituted by ffmpeg?

Thank you very much
