        @jsulm Yeahh. I have read it but I don't think that Rate of playback means speed :( Thank you

          @Hung-Tran It does. What else could it be?
          "By default this value is 1.0, indicating that the media is playing at the standard pace. Values higher than 1.0 will increase the rate of play. Values less than zero can be set and indicate the media will rewind at the multiplier of the standard pace."
          A value of 2.0 would play the media file at doubled speed.
