Thanks for the reminder Carl. Here is the uncut command line that I'm
using for the ffmpeg extraction, followed by the full console output. The
VLC command line is already shown in its full form.
ffmpeg -ss 24.579605 -t 54.91519 -i

-t is not an input option, keeping it for the next output; consider fixing
your command line.
