The FFMPEG command I am using for scaling then cropping is working perfectly in 5 of 6 cases I am processing, but for a reason I don't understand in one case it is not working at all.
dimensions of input jpg file = 774x1032
- dimensions of output jpg file = 1000x1000 --> OK
- dimensions of output jpg file = 400x200 --> OK
- dimensions of output jpg file = 750x200 --> OK
- dimensions of output jpg file = 350x200 --> OK
- dimensions of output jpg file = 400x350 --> OK
dimsions of output jpg file = 200x200 --> ERROR
ffmpeg -y -i input.jpg -vf "transpose=clock:passthrough=landscape,scale=(iw*sar)max(200/(iwsar)\,200/ih):ihmax(200/(iwsar)\,200/ih),crop=200:200" -q:v 1 output.jpg;
this is running in a batch process, taking as input hundred of files, and always happen the same when scaling&cropping to 200x200...
the ffmpeg output is
