Looping MediaElement freezes after some minutes or halts for a second

Question

I have a .net framwork (4.7.2) wpf application in which a video (duration: 10 to 50 seconds) should be looped all day long.

First I have implemented the way which is suggested by mirosoft (using a story board): How to: Repeat Media Playback (learn.microsoft.com)

<MediaElement Name="VideoMediaElement" Width="1920" Height="1080" Visibility="{Binding Path=IsVideoUriAvailable, Converter={StaticResource BooleanToVisibilityConverter}}">
    <MediaElement.Triggers>
        <EventTrigger RoutedEvent="MediaElement.Loaded">
            <EventTrigger.Actions>
                <BeginStoryboard>
                    <Storyboard>
                        <MediaTimeline Source="{Binding Path=VideoUri, FallbackValue=null}" Storyboard.TargetName="VideoMediaElement"
                                       RepeatBehavior="Forever" />
                    </Storyboard>
                </BeginStoryboard>
            </EventTrigger.Actions>
        </EventTrigger>
    </MediaElement.Triggers>
</MediaElement>

But on my test I noticed that the video feezes after 3 to 5 minutes.
I found this article, which descripes the same problem.
The solution: Using a 3rd party library or manage the repetition yourself.

I want to avoid using the suggested library, because it looks like it is no longer maintained. So I implemented the (very simple) solution.

<MediaElement Name="VideoMediaElement"
              Width="1920" Height="1080" 
              Visibility="{Binding Path=IsVideoUriAvailable, Converter={StaticResource BooleanToVisibilityConverter}}"
              Source="{Binding Path=VideoUri, FallbackValue=null}"
              LoadedBehavior="Manual"
              Loaded="Video_OnLoaded"
              MediaEnded="Video_OnMediaEnded"/>

private void Video_OnLoaded(object sender, RoutedEventArgs e)
{
    VideoMediaElement.Play();
}

private void Video_OnMediaEnded(object sender, RoutedEventArgs e)
{
    VideoMediaElement.Position = TimeSpan.FromSeconds(0);
}

It seems this implementation is more reliable, but I have still one problem: the video stops for like one second when OnMediaEnded is fired. After that short halt the video start at the beginning.

Do you have any suggestions how to fix this short halt?

Answer 1

private void Video_OnLoaded(object sender, RoutedEventArgs e)
{
    VideoMediaElement.Play();
}

private void Video_OnMediaEnded(object sender, RoutedEventArgs e)
{
    VideoMediaElement.Position = TimeSpan.FromSeconds(0);
    VideoMediaElement.Play();
}
