 Summary of the bug:
 I am trying to generate .ogg samples from the middle 30 seconds of a batch
 of mp3 files. The file durations are retrieved from ffprobe and are
 generally orrect. However when the actual duration is smaller, the ffmpeg
 command falls into an infinit loop of logging error. Ideally, the ffmpeg
 process should terminate/crash immediately.
 How to reproduce:
 {{{
 % ffmpeg -report -i ashoobam.mp3 -codec:a opus -strict -2 -ss 1000 -t 30
 x.ogg
 ffmpeg version: 4.0.3
 built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.10)
 }}}
