UWP 播放直播流 3MU8

Create new Windows 10 project and go to MainPage.xaml page design view to design.

Add Media control to play the streamed videos and use the following code to design media control:

<Grid>  

   <MediaElement x:Name="liveMedia" />  

</Grid>  

Next add two app bar controls to Play and Pause the streaming.

<Page.BottomAppBar>  

   <AppBar IsOpen="True">  

      <StackPanel Orientation="Horizontal">  

         <AppBarButton Name="playBtn" Click="playBtn_Click" Icon="Play" Label="Play"></AppBarButton>  

         <AppBarButton Name="pausBtn" Click="pausBtn_Click" Icon="Pause" Label="Pause"></AppBarButton>  

      </StackPanel>  

   </AppBar>  

</Page.BottomAppBar>  

Next go to code behind page and write the following code to stream the video:

var streamUri = new Uri(""); //replace your URL  

var streamResponse = await AdaptiveMediaSource.CreateFromUriAsync(streamUri);  

if (streamResponse.Status == AdaptiveMediaSourceCreationStatus.Success)  

liveMedia.SetMediaStreamSource(streamResponse.MediaSource);  

else  

{  

   //not found  

}  

Before set the media source check the status property to verify that everything went correct otherwise skip it.

By default it will start playing the stream. If you want to pause write the following code:

private void pausBtn_Click(object sender, RoutedEventArgs e)  

{  

   liveMedia.Pause();  

}  

If you want to play again write the following code:

private void playBtn_Click(object sender, RoutedEventArgs e)  

{  

   liveMedia.Play();  

}  

You can play around the media control like the following function: pause, play, mute, unmute and volume increase etc.

Now run the app and check the output like the following video. Here I am going to stream the live news channel.
