[FFmpeg-user] Cropdetect in ffmpeg version 4.1.4_1

[Ted Park]

> Is there a change to cropdetect in ffmpeg v.4.1.4_1? I've been using “ffmpeg -i input -t 1 -vf cropdetect -f null - 2>&1 | awk '/crop/ { print $NF }' | tail -1” for a long time, and now it appears to yield no output. Thanks.

Seems to work fine, you could try removing the piped commands from the end to see where it goes wrong (try getting rid of tail, then awk, and the output redirection, and so on.)
