how to use ffmpeg in wpf?

Question

I am using wpf and want to capture the desktop and then save mp4 to file.

better add some text.

I searched that I can get the device list using the command:

ffmpeg -list_devices true -f show -i dummy

can I do it in dll? I mean add the ffmpeg from nuget and get the device list by cs code.

not to run a command?

You can use native Win32 interfaces, like

IMFCaptureEngine with P/Invoke

(tested on Windows 10 22H2 from MS SDK sample https://github.com/microsoft/Windows-classic-samples/tree/main/Samples/CaptureEngineVideoCapture )
