Concat: durations of inputs (or playlist entries) summed.
ImageOutput = 2
Output is an image sequence — we measure progress in frames.
ImageInput = 3
Input is an image sequence, output is a video — we measure in seconds, with total = frames/framerate.
Unknown = 4
We can't figure it out; let ffmpeg's own progress print pass through.
