      public boolean isStepping()

    • skip

      public void skip(long frame)
      Skips to the given frame.
      Parameters:
      frame - The frame number.

    • checkKeyframeTimings

      public boolean checkKeyframeTimings()
      Checks that all keyframe timings fall perfectly on a frame, so that t(kf) * FPS % 1 = 0 holds.
      Returns:
      True if the keyframe timings are consistent with the camcorder FPS setting.
