+*  @return                         An error code

+*  @remarks
+*                   - This method only works for the PLAYER_STATE_PLAYING, PLAYER_STATE_PAUSED, and PLAYER_STATE_OPENED states of the player instance.
+*                   - This method is not guaranteed to work correctly when the content does not have key frames.
+*                   - This method is faster than @SeekTo() but the seeking accuracy is worse than @SeekTo().
