[WPF] No preview when AllowsTransparency is True

Products: Video Capture SDK .Net, Video Edit SDK .Net, Media Player SDK .Net

If you are using WPF and have set the AllowsTransparency property of the application window to True you may see a black screen instead of video in the VideoView element.

To solve this problem, set the video renderer to VideoRendererMode.WPF_WinUI_Callback instead of VideoRendererMode.EVR.
