Under X86-64 SL6x, I have successfully built vlc-2.0.7 from source with 
the configure command:

  ./configure --disable-lua --disable-mad --disable-avcodec 
--disable-swscale --disable-postproc --disable-a52

the resulting vlc does run , but cannot open many types of files, 
including files of extension webm

Does anyone know either which RPMs or which files/libraries that need to 
built from source will address the above shortcomings, irrespective of 
the geographical location from which these must be downloaded?
