Show first frame of video in WPF MediaElement

You also need

ScrubbingEnabled="True"

Then set an event on Load

Loaded="Video1_Loaded"

In the Video1_Load method add the following:

Video1.Play();
Video1.Pause();

None of the video content is rendered before the play method is called. So even if you set the position past the first frame you won't get any data rendered.

I think the MediaElement.ScrubbingEnabled Property is the key.

Gets or sets a value that indicates whether the MediaElement will update frames for seek operations while paused. This is a dependency property.

I tried the same approach without ScrubbingEnabled but found that the first frame wouldn't render. Not sure if it's just the hardware I am using for this. The other item to remember is that the way the MediaElement works, once you call Play() you may not actually Pause() on the first frame exactly, so you may want to reduce the volume on the stream before calling Play() and reset after calling Pause().

You don't have to create an event, see following

<MediaElement Source="foo.wmv" 
              MediaOpened="videoElement_MediaOpened" 
              LoadedBehavior="Pause" ScrubbingEnabled="True" />

I can't comment, so here is my answer: Scrubbing refers to updating the rendered image when the MediaElement is paused.

//Todo: Set your source

//if not stated in the xmal, you can still set this here.
Player.LoadedBehavior = MediaState.Manual;

//Turn scrubbing on
Player.ScrubbingEnabled = true;

Player.Pause();

Player.Position = TimeSpan.FromTicks(1);

Thanks for the scrubbing tip!
