Comment:

 What happens if {{{ffmpeg}}} is used as pipe sink? Or a file?
 Does using {{{-f lavfi -i testsrc=r=1}}} as input allow to reproduce the
 issue?

 To make this a valid ticket please provide a simplified command line that
 allows to reproduce the issue together with the complete, uncut console
 output.
