Hi!
I have a problem with MediaElement control. I've put six MediaElements on my form, then I start them and change played files by timer.
After several times, these elements stop playing.
Here is the sample XAML:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<MediaElement x:Name="element1" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="0" />
<MediaElement x:Name="element2" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="0" />
<MediaElement x:Name="element3" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="0" />
<MediaElement x:Name="element4" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="1" />
<MediaElement x:Name="element5" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="1" />
<MediaElement x:Name="element6" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="1" />
Here is the sample code:
// The code below repeats for each MediaElement
List<string> playlist1 = new List<string>()
{
@"file1.wmv",
@"file2.wmv",
@"file3.wmv",
@"file4.wmv"
};
DispatcherTimer timer1 = null;
int index1 = 0;
...
void Window1_Loaded(object sender, RoutedEventArgs e)
{
timer1 = new DispatcherTimer();
timer1.Tick += new EventHandler(timer1_Elapsed);
timer1.Interval = TimeSpan.FromSeconds(10);
element1.Source = new Uri(playlist1[index1]);
timer1.Start();
element1.Play();
...
}
void timer1_Elapsed(object sender, EventArgs e)
{
Dispatcher.BeginInvoke(DispatcherPriority.Normal, (System.Threading.ThreadStart)delegate()
{
element1.Stop();
element1.Close();
timer1.Stop();
index1++;
if (index1 >= playlist1.Count)
{
index1 = 0;
}
element1.Source = new Uri(playlist1[index1]);
timer1.Start();
element1.Play();
});
}
...
Does anybody have similar problems?
