Video cannot be output with the application

PostThu Mar 19, 2020 9:18 am

I am developing an application that outputs video, captured by DecklinkStudio4K using DecklinkDirectshowLibrary.

However, the output window remains a black screen.

DecklinkCapture.exe can be seen.

When I check the parameter with GetVideoInputStatus of IDecklinkStatus Interface, videoStatus is set to 0.

What should I do to output normally?

The filter configuration is as follows.

DecklinkVideoCapture--->BlackmagicDesign Decoder(DMO)--->
WMVideo9 Encoder DMO--->Original distribution filter

The format of the input video to Decklink is 1920x1080p24, YCbCr 4: 2: 2, 8bit.

Thank you.
