   	ffmpeg can be built with support for lots of different video   
   formats. Anybody know exactly how the package is built for Slackware64   
   15.0?   
      
   	I had a look into the corresponding Slackbuild file, as   
   distributed with Slackware64 15.0, and it would seem that the decision as   
   to whether or not add support for some specific format is done on the   
   fly, depending on whether or not the necessary shared libraries are   
   already present in the system. Which, of course, is something I cannot   
   know, when it comes to the ffmpeg package distributed with Slackware64   
   15.0.   
      
   	The thing is, I am trying to do something with ffmpeg that   
   requires the x264 encoder, and ffmpeg claims not to know about such   
   encoder.
