I took the Big Bug Bunnys HD encodes as samples and there it works as
expected:
$ for i in *; do ffmpeg -i "$i"; echo "without skip, with filters"; time ffmpeg -
i "$i" -filter:v cropdetect -filter:a volumedetect -map 0:a -map 0:v -f null
/dev/null 2>/dev/null; echo "with skip, with filters"; time ffmpeg -skip_frame
nokey -i "$i" -filter:v cropdetect -filter:a volumedetect -map 0:a -map 0:v -f
null /dev/null 2>/dev/null; echo "with skip, without filters"; time ffmpeg -
skip_frame nokey -i "$i" -map 0:a -map 0:v -f null /dev/null 2>/dev/null; echo
"without all"; time ffmpeg -i "$i" -map 0:a -map 0:v -f null /dev/null
2>/dev/null; echo ------------; done
