That's ffplay.

  $ man ffmpeg-all 2> /dev/null | wc -l

why are you redirecting stderr? does `man ffmpeg` produce error output on your system?

anyway, on my system (macOS, ffmpeg 4.3.1 from Homebrew) the situation is even more dire:

    $ man ffmpeg-all | wc -l

On my system (Kubuntu 20.04) man/troff produces errors when its output is redirected:

  $ man ffmpeg-all | wc -l
  troff: <standard input>:6148: warning [p 42, 3.5i, div 'an-div', 0.0i]: can't break line

No idea what it means.
