Can be reproduced with PlaybackWpfUser sample. Steps to reproduce:

1. Press left mouse button on ImageViewerWpfControl.

2. Hold the button and drag the mouse over to PlaybackWPUserControl timeline.

3. Release the button.

This crash only occurs if the timeline of playback control wasn’t dragged.

Using 2017 R3 or 2018 R1.

Hi Anders,

I am facing the same problem.Please find the log and code details below.

MyCode:

private void EnablePlayback()

{

  if (true)

  {         

    \_playbackUserControl.Visibility = Visibility.Visible;

    try

    {

      \_playbackUserControl.ShowTallUserControl = true;

      \_playbackUserControl.ShowSpeedControl = true;

      \_playbackUserControl.ShowTimeSpanControl = true;

      \_playbackUserControl.SelectionFromTime = TempTimeStamp.Date;

      \_playbackUserControl.SelectionToTime = TempTimeStamp.AddDays(1).Date;

      \_playbackUserControl.TimeSpan = new TimeSpan(0, 1, 0);

      \_playbackUserControl.SetSequence(TempTimeStamp.

        TimeStamp.Subtract(new TimeSpan(0, 0, 30)), TempTimeStamp.AddSeconds(60));

      \_playbackUserControl.SetEnabled(true);

      \_imageViewerControl.StartBrowse();

      EnvironmentManager.Instance.SendMessage(new VideoOS.Platform.Messaging.Message(

      Console.WriteLine("Done.");

    }

    catch (Exception e1)

    {

      Console.WriteLine("Error:" + e1.Message);

    }

  }

}

@Ashwin Amarapuram Chandramouly​ We can not reproduce the error that you reported. I assume that you TempTimeStamp is set as minimum value and subtraction on that value gives you that error. Furthermore, SelectionFromTime and SelectionToTime properties are not supported for standalone playbackUserControl. You can find that information in the SDK documentation.
