Failed to Open Media!

[Tahir Ahmed]

Hello,

I am testing a simple implementation of Rad Silverlight MediaPlayer but it is not working, whenever I click on play button it says "Failed to Open Media!".

    <Grid x:Name="LayoutRoot">
        <telerik:RadMediaPlayer x:Name="player" Header="Sample Video">
            <telerik:RadMediaItem Name="MyMediaItem" IsStreamingSource="True" Title="My Video" Source="/vids/BF3.wmv" StreamAttached="RadMediaItem_StreamAttached"></telerik:RadMediaItem>
        </telerik:RadMediaPlayer>
    </Grid>

        private void RadMediaItem_StreamAttached(object sender, EventArgs e)
        {
            var item = sender as RadMediaItem;
            if (item != null)
            {
                var adaptiveSource = new AdaptiveStreamingSource();
                adaptiveSource.MediaElement = player.MediaElement;
                adaptiveSource.ManifestUrl = item.Source;
                adaptiveSource.StartPlayback();
            }
        }

I have placed vids folder in Bin, Debug and main project folder where App.xaml is located but it is not working. I have already encoded the video in Expression Encoder 3. I checked this thread as well.

But it is still not working. What should I do ? Please help.

Hi Tahir,

From your code snippet I noticed that you're setting the source of the MediaItem to a wmv vide, but if you want to use smooth streaming you need to point the source of the RadMediaItem to the manifest file of the video.
Please have a look at this demo sample and this help article. They can help you implement your scenario.

Let us know if we can further assist you.

Thanks Tina for pointing that out and providing helpful links I just started with Silverlight Tools so don't have any knowledge about them, I was just following the example "SmoothStreaming" and didn't pay attention to the URL of RadMediaItem, it looks like it requires some study of Expression Encoder.

For example if I want to play a simple media file like a WMV or MP4 file without smooth streaming then what should I do ? can you provide an example ?

Thanks.

okay got it work with the following code

        <telerik:RadMediaPlayer x:Name="player" Header="Sample Video">
            <telerik:RadMediaItem Name="MyMediaItem" Title="My Video" Source="/vids/BF3.wmv" ></telerik:RadMediaItem>
        </telerik:RadMediaPlayer>

I removed IsStreamingSource = "True" and then it worked.

Might help some beginner like me :)

Marking your answer Tina, since it showed me the right direction, thanks.
