The links above show text that appears to be cut off with no scroll bar and
the output largely appeared on one line, but I eventually figured it out.

In each of these, the fps output I see I believe is the rate
at which frames are being encoded.   In other words - how fast 
ffmpeg is able do the the encoding as opposed to the ultimate playback rate.

Hope that helps.
