title: how to link ffmpeg to php.ini
body: <p>hi i am using mac osx with mamp and i was wondering how i can link ffmpeg to php.ini so that i can use it with php exec() ?</p>
  
  <p>the directory that ffmpeg got installed in is /users/sarmenhb/ffmpeg although i wish it didnt get installed here and got installed somewhere more appropriate, i sadly have no clue how to change the system to know where the new location is.</p>
  
  <p>i read a few articles telling me to put something like extensions = /users/sarmenhb/ffmpeg/ffmpeg.so but looking in the directory i dont see a so file. i do see ffmpeg as a console app is that an so file itself?</p>
  
  <p>thanks</p>
  
  <p>ps: i did a test of ffmpeg in console from a flv file to a mp4 file and the audio didnt work on the new file. do i have to install something?</p>
