Live Stream switching durations issue...

06-25-2009 7:04 AM |

I am experiencing some issues with live stream change responsiveness.

To isolate this issue I have a simple test project which points to an OnDemand publishing point which in turn points to the playlist (below).

The xaml media element points to this (<MediaElement x:Name="VideoElement" Source="mms://server:49000/testODPP" BufferingTime="00:00:00.000"/>)

<?wsx version="1.0"?>
<smil>
        <media id = "1" dur="2" src="http://server:49000/SLLiveStream1"/>
        <media id = "2" dur="2" src="http://server:49000/SLLiveStream2"/>
        <media id = "3" dur="2" src="http://server:49000/SLLiveStream1"/>
        <media id = "4" dur="2" src="http://server:49000/SLLiveStream2"/>
</smil>

The first media item plays for 2 seconds in the Silverlight 2.0 player, however, the following media items linger for up to 8 seconds each.

Is it possible I am missing some basic buffer configurations for live streaming?

Any help would be greatfully appreciated.

Thanks

Jamie.
