You can also use MFCreateSinkWriterFromMediaSink() with a custom sink
stub and see what happens. It's a legitimate use case, because sinks are
supposed to be external plugin-like objects.
I created a writer from mp4 media sink. Before calling BeginWriting() on writer, GetPresentationClock() on that sink returned MF_E_NO_CLOCK. After BeginWriting(), it returns a valid clock.
The test code is attacted: [clock_test.c](/uploads/27be06ce75c1c05e51fe04a6bde08b13/clock_test.c).
