Hmm, that's strange. Especially as those are pure FFmpeg internal code.

Can't reproduce :(
The missing symbols are in my mplayer binary I just built.

Not sure if it will help, but might be worth to try:

   make distclean

Then build again from scratch.


Are you using anything extra, besides --enable-gui ?
