Audio -plugins can be used for changing the properties of the audio data before -the sound reaches the sound card. They are enabled using the - switch which takes a - argument. The - argument is required and determines which plugins -should be used and in which order they should be executed. Example: - -mplayer media.avi -aop list=resample,format - -would run the sound through the resampling plugin followed by the format -plugin. - - - -The plugins can also have switches that change their behavior.
