Nikolay Sivov (@nsivov) commented about dlls/mf/tests/mf.c:
+ PropVariantClear(&propvar); + + /* Place an ENDOFSEGMENT marker after the third sample */ + hr = IMFStreamSink_PlaceMarker(stream, MFSTREAMSINK_MARKER_ENDOFSEGMENT, NULL, NULL); + ok(hr == S_OK, "Unexpected hr %#lx.\n", hr); + + hr = gen_wait_media_event_until_blocking((IMFMediaEventGenerator*)stream, callback, MEStreamSinkMarker, 1000, &propvar); + ok(hr == S_OK, "Unexpected hr %#lx.\n", hr); + PropVariantClear(&propvar); + + /* Check clock time */ + while (time <= 300000) + { + IMFPresentationClock_GetTime(clock, &time); + Sleep(50); + } This does not look very safe to me. If we must to do GetTime(), maybe do it in a separate thread, and have a timeout?
