     * find a keyframe. Any data after the offset already buffered from a previous stream is flushed.
     * This technique can switch to a new stream more quickly than standard switching, because the buffered data from an older stream
     * doesn't have to play out.The default value of offset is -1, which is fast switch mode. In this mode, switching occurs at the first available keyframe after netstream.time + 3,
     * which is about 3 seconds later than the playback point.The offset value must be higher than the current playback time (Netstream.time)
     * If the value is less, a NetStream.Play.Failed status event is sent.For more information, see "Fast switching between streams"
     * in the Adobe Flash Media Server Developer's Guide.
