Hello,

Welcome to Microsoft Q&A!

If you want to create custom sink.

I suggest you could refer to the Doc: Using Custom Sinks

To create your own sink, implement the IWMWriterSink interface in a class in your application.

If you want to know how to get the IMediaExtension.

I suggest you could refer to the sample:https://github.com/microsoft/Windows-universal-samples/blob/main/Samples/SimpleCommunication/cs/CaptureDevice.cs

// Create new sink
                mediaSink = new StspMediaSinkProxy();
                mediaSink.IncomingConnectionEvent += mediaSink_IncomingConnectionEvent;

                var mfExtension = await mediaSink.InitializeAsync(encodingProfile.Audio, encodingProfile.Video);
                await mediaCapture.StartRecordToCustomSinkAsync(encodingProfile, mfExtension);

According to the sample, as far as I'm concerned, you could get IMediaExtension from MediaEncodingProfile.

Thank you.

Jeanine
