The frames in RAM is actually a larger part, the time between two spinups.
But you're right, we could loop a few frames back and forth. This will then
always move back and forth also, may look very funny depending on the scene.
I just haven't spent much effort on the paused mode, and doubt I will. Be
glad there is a pause at all...
One thing the pause does: It re-syncs the video, in case it has drifted away
from the audio (may happen after prolonged playback). For sure this works
only if your encoding was correct. If the video frame rate was given wrong to
the command line tools, I can't help it.

There is no part that represents a single frame, it's all a continuous flow.
