Winff 1.5.5 on Kubuntu 17.04, hp p6-2175a (i3), which uses ffmpeg
7:3.2.4-1build2 (this time, though historical):
ffmpeg 1st pass window:
/usr/bin/ffmpeg -y -i "/drv2/My
Videos/_aMule/Incoming/Formula.One.17.United.States.Grand.Prix.720p.HDTV.x264-VERUM.[tvu.org.ru].mkv"

Error message in Konsole, Kubuntu's Terminal:
[ac3 @ 0x563f33722b60] exponent 25 is out-of-range1:01:02.99
bitrate=1447.7kbits/s dup=53 drop=0 speed=1.36x
[ac3 @ 0x563f33722b60] error decoding the audio block

The error message is actually the two "ac3 @" lines, the first ([ac3 @
0x563f33722b60] exponent 25 is out-of-range) overwrites the underlying
progress line (which gives the point at which the error occurs, 1 hour,
consistently), and is probably the important one.
That last line, (frame ... 1.25x) is ongoing progress.
(Incidentally, the progress line is padded out to beyond Konsole's
default width, resulting in screensful of progress lines until widening
the view, at which point it overwrites itself)
The error seems to be non-fatal; the process continues to completion and
the result seems to be unaffected.
Hopefully enough to work on ...
Cheers
Dex
