Hi

​

I am using ImageViewerWpfControl in C#.

​

I want to detect when no Image is recorded at the playback position (including Reverse and Goto).

what should i do?

I want you to tell me.

​

Best regards,

For a nice overview of the portions of the timeline with recording or no recording you can use SequenceDataSource. Explore this sample: https://doc.developer.milestonesys.com/html/index.html?base=samples/pluginsamples/scsequenceviewer/readme.html&tree=tree_1.html

For a more direct comparison between the picture displayed and the time line you can use

EventHandler<ImageDisplayedEventArgs> VideoOS.Platform.Client.ImageViewerWpfControl.ImageDisplayed = delegate { }

and compare to

virtual DateTime VideoOS.Platform.Client.PlaybackController.PlaybackTime
