[PATCH 1/5] mf/tests: Check the number of input samples to get a H264 stream change.

[Rémi Bernon]

This is not completely exact, and depending on how often ProcessInput
and ProcessOutput are called the numbers may vary a bit, but this
version seems to be consistent enough. We could very well ignore the
checks too as GStreamer output doesn't seem to match.

We check that we can at least push two input samples at a time, which
matches what Call of Duty Black Ops 3 is doing, as it is not checking
ProcessInput result most of the time.
