FFMPEG crash while cropping video
18 octobre 2022, par Khawar RazaI am using FFMPEG to crop a video. I am using ffmpeg-kit as a ffmpeg wrapper in my android app where the user can select any output size irrespective of the original video aspect ratio. Below is the problematic command :


-i "/storage/emulated/0/Download/83a2f6_1080p~2.mp4" -filter_complex "[0:v]crop=304:236:2:2[cropped]" -map "[cropped]" "/storage/emulated/0/DCIM/appname/vid_d8ee328d-ec7a-468b-9313-4561dceea33e.mp4"



When the execution starts, the application crashes.

I don't know what is wrong with the output width and height parameters. If I change
[0:v]crop=304:236:2:2[cropped]
to[0:v]crop=304:304:2:2[cropped]
with change in height, the process completes successfully. The original video (1080x808) is not smaller than the output size. It does not seem to be a problem in the video as I have tried different videos. Any tips on what is missing from my command ?
