During encoding, could the status include fps?  It currently looks like this:
Pass 1/2 frame 14315/14316 2176032B    1216b/f   29186b/s  230825 ms (62.02 
fps)←[K
Pass 2/2 frame 13936/13920 85459531B ←[K   3310F
When complete, the fps is shown.  If the fps, so far, were shown during 
encoding, time to completion could be computed.

This is a known issue Vp9 its not been optimized. We should check later when 
the codec is better optimized.

If you ask for --psnr the values are shown as the compression proceeds.
Can the same be done for encode fps?
