- Microsoft Windows CE 5.0
SYMPTOMS
In Microsoft Windows CE 5.0, if you play an MPEG1 video stream from Microsoft Media Server and then you pause the video stream for a long time, you may experience poor playback performance when playback is resumed.
CAUSE
This problem occurs because the available bandwidth is calculated from the time that the video was started. When you pause the video, the calculation by the filtergraph reports a problem and then tells the server to slow down the video stream. A filtergraph is a Directshow component that converts input from one format to another. In this case, the filtergraph sends messages back to the server to pause the stream.
