Workaround issue with stdin on Windows.
On Windows, sometimes the compare_videos.py script fails because
the inherited stdin handle from the parent process fails.
It seems we can work around this by passing null to stdin to
the subprocesses, since we're not using it anyway.
The errors looked like this:
Traceback (most recent call last):
