[FFmpeg-user] Feature request: show the "speed" of audio only conversions

[Roger Pack]

Good day.  Sorry if this is a repeat, but sending it on again just in case:

Currently when FFmpeg does an "audio only" conversion, it shows a
progress output thusly:

size=  499284kB time=00:14:47.61 bitrate=4608.0kbits/s

what it "lacks" (in my opinion) is an audio equivalent to the "fps=
59" that is shown during a video conversion progress bar:

frame=  386 fps= 59 q=2686559.0 Lsize=     959kB time=00:00:12.81
bitrate= 613.0kbits/s dup=31 drop=1

Suggestion/feature request: make audio progress bar include a "seconds
per second" metric, or otherwise, like

size=  499284kB time=00:14:47.61 bitrate=4608.0kbits/s speed= 1.9 s/s

So you can see how many seconds (and thus infer how long the entire
process will take) more easily.

Thank you.
Kind regards.
