When encoding FFmpeg prints a new line every second with the progress, example

frame=   31 fps=0.0 q=0.0 size=     152kB time=00:00:00.72 bitrate=1726.3kbits/s
frame=   59 fps= 57 q=0.0 size=     175kB time=00:00:01.90 bitrate= 751.1kbits/s
frame=   89 fps= 58 q=0.0 size=     204kB time=00:00:03.04 bitrate= 549.8kbits/s

With a large file these lines can quickly fill the console screen. I would like to see the progress on one line if possible, that is to say each second the same line is overwritten with the updated progress.

At least with Windows, FFmpeg requires 85 columns to print progress correctly. I set this using the registry

sp hkcu:console WindowSize 0x00190055 -t dword
sp hkcu:console ScreenBufferSize 0x03e80055 -t dword
