Rémi Bernon (@rbernon) commented about dlls/mfsrcsnk/tests/mfsrcsnk.c:
IMFByteStream_Release(bytestream);

+struct source_create_callback
You'll need to squash these helpers with the next change. Also I think it'd be better to introduce another different flavor of mock test callback. I'm sure the test_callback from mf/tests/mf.c can be copied here with little adjustments to fit the needs for these tests (more in other comments).
