Description
The recording function is implemented by referring to the Win7Samples\multimedia\mediafoundation\MFCaptureToFile code.
However, when I repeatedly start/stop recording on this sample, I get a handle leak.
I've seen it increase in task manager.
I suspect IMFSinkWriter.
If the handle is not cleaned in IMFSinkWriter, I hope that the latest version includes the MF modified version.
Can I get some hints on how to solve the related problem?

Research direction
Start by comparing the recording function with Win7Samples\multimedia\mediafoundation\MFCaptureToFile and reproduce the leak by repeatedly starting and stopping recording. Use Task Manager to confirm handle growth and investigate the suspected IMFSinkWriter cleanup path. Done means identifying the leaking handle and documenting or correcting its cleanup behavior.
