 Duplicate of ticket #2349 (I do not really understand how this can be
 relevant on osx but for small console windows it is reproducible on all

 The windows build package don't have `ffmpeg_g` file for use in gdb, and
 when I use gdb with ffmpeg give me this error:

 Currently, in FFmpeg 3.4.1 (macOS/Homebrew), the progress line is linked
 to a certain log level. This makes it impossible to reduce verbosity while
 still displaying the progress line.

 Suggest to make a separate command line switch for enabling/disabling
 progress. Default should obviously be enabled.

 Summary of the bug:

 The progress line in FFmpeg 3.4.1 on macOS/Homebrew requires at least ~110
 columns wide terminal, or else the line will be repeated and flood the
 terminal each time they are printed (quite annoying!)

 {{{
 frame= 1073 fps=106 q=28.0 size=3840kB time=00:00:43.02 bitrate=

 }}}


 Suggestion: Given each element a priority, so that when the window
 shrinks, the elements disappear intelligently one by one (1=Stays longest,
 9=Goes first)

 4 frame= 1073
 6 fps=106
 5 q=28.0

 Happens to me as well, when source and destination dimensions match for
 scale_npp.
