Cropdetect in ffmpeg version 4.1.4_1

llee782
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.)

Thanks. I’m not having any trouble with it now, so I must have put the blame in the wrong place. Maybe I left out the important troubleshooting step of changing video sources as I thought I had. Anyway, never mind.
