Using external codecs

Although ffmpeg is a so powerful codecs package, sometimes it can't do it right for some codec, such as Real Codecs. MPlayerX could take advantage of external codecs, but it needs some work.

1. open Terminal in /Applications/Utilities/
2. cd ~/Library/Preferences/
3. type defaults write org.niltsh.MPlayerX Prefer64bitMPlayer 0

this hidden setting will force MPlayerX to use the 32bit version of mplayer, whatever your Mac has a 64bit CPU or not.

4. right-click MPlayerX > show Package Content, goto Contents/Resources/binaries/m32/codecs
5. copy the codec binaries into MPlayerX.app/Contents/Resources/binaries/m32/codecs/

(e.g Real Codec binaries in RealPlayer.app/Contents/Frameworks/HXClientKit.framework/HelixPlugins/Codecs/*.bundle)
