These tests serve to illustrate the output sample time and duration values from their respective native MFT video decoders with respect to the following circumstances:
1. When no frame rate nor input sample timestamps are provided;
2. When a frame rate is provided but there are no sample timestamps; and
3. When a frame rate is provided, but the input sample timestamps disagree with this value
It also highlights the gap in our implementation. However, I don't believe this can be fixed without first confirming the correct output from our IMFMediaStream implementations.
