Comment:

 Hello ffmpeg devs.
 I want to jump onto this ticket as I am having the same problem.
 Implications are a bit different though.
 I am calling ffmpeg.exe from external program. This issue causes ffmpeg to
 continously output

 and does not terminate without user input. This was not present back in
 ffmpeg version 3.2.4.
 I tried every version since then including the latest stable and this
 issue persists.

 I am fine when ffmpeg is having an error when being called. So my problem
 is not to resolve the error. My problem is that ffmpeg does not terminate
 when this error happens and my external program cannot continue unless
 manually q pressed.
