This strongly depends on the accuracy of the duration in the container.
I think the most reliable way to get the very last frame is to catch the
frames from a pad probe in front of the sink. Seek to near the end, let
it run until EOS and always remember the last frame you saw. In the end
you'll definitely have the last frame.
