[HELP] Silverlight hangs browser for 28 seconds when first setting the source URI

04-29-2009 11:12 AM |

For some reason when I set the media source, the browser seems to hang until the media starts to play. If I change autoplay = false on the initial load it does not hang, but if I then change the uri to another video and set autoplay = true. It then hangs. So basically the first time I set the source and play the video it hangs for 28 seconds. The server is windows 2008 with windows media services. Any suggestions would be very welcome, I have been banging my head on this for a few days now. It hangs on this line of code when stepping through:

this.media.Source = this.mediaSourceUri;

here are the properties:

        [System.ComponentModel.Category("Media Player Properties"), System.ComponentModel.Description("Sets the media source Uri.")]
        public Uri MediaSourceUri
        {
            set
            {
                this.mediaSourceUri = value;
                this.clickToPlayGrid.Opacity = 1;
                this.clickToPlayGrid.IsHitTestVisible = true;
            }
        }

 /// <summary>
        /// Gets or sets the media source.
        /// </summary>
        [System.ComponentModel.Category("Media Player Properties"), System.ComponentModel.Description("Sets the media source.")]
        public string MediaSource
        {
            get { return (string)GetValue(MediaSourceProperty); }
            set { SetValue(MediaSourceProperty, value); }
        }

        /// <summary>
        /// Updates the media source Uri.
        /// </summary>
        /// <param name="dependencyObject">The media player.</param>
        /// <param name="eventArgs">Dependency property changed event args.</param>
        private static void MediaSource_Changed(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs eventArgs)
        {
            MediaPlayer mediaPlayer = (MediaPlayer)dependencyObject;
            mediaPlayer.MediaSourceUri = new Uri((string)eventArgs.NewValue, UriKind.RelativeOrAbsolute);
        }

Let me also add that this happens not only when setting the source to our media server but even when I use Microsofts http streaming server.
