Set buffering times

The MediaPlayer provides methods to set and get the initial buffering time and playback buffering time.


If you do not set the buffer control parameters before beginning playback, the media player defaults to 2 seconds for the initial buffer and 30 seconds for the ongoing playback buffer time.

  1. Set up the BufferControlParameters object, which encapsulates the initial buffer time and playback buffer time control parameters:

    This class provides the following factory methods:
    • To set the initial buffer time equal to the play buffer time:

    • To set both the initial and play buffer times:

      createDual(initialBufferTime:uint, playbackBufferTime:uint):BufferControlParameters 

      These methods throw an IllegalArgumentException if the parameters are not valid, such as when:

    • The initial buffer time is less than zero.

    • The initial buffer time is greater than the buffer time.

  2. To set the buffer parameter values, use this MediaPlayer method:

    public function set bufferControlParameters(value:BufferControlParameters):void
  3. To get the current buffer parameter values, use this MediaPlayer method:

    public function get bufferControlParameters():BufferControlParameters

For example, to set the initial buffer to 2 seconds and the playback buffer time to 30 seconds:

mediaPlayer.bufferControlParameters = BufferControlParameters.createDual(2000, 30000); 

The psdkdemo demonstrates this feature; use the application’s settings to set the buffer values.
