Flutter ffmpeg kit : Invalid size error when trying to scale video
27 juillet 2023, par veryepicdudeI'm trying to resize a video to match instagram's video format requirements. I'm using the
ffmpeg_kit_flutter_full_gpl: ^5.1.0
package to do so and this is the function I'm calling :

Future<void> resizeVideo(String input, String output) async {

 final command = '-i $input -c:v libx264 -aspect 16:9 -crf 18 -vf "scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih),pad=1280:720:(1280-iw)/2:(720-ih)/2" -fpsmax 60 -preset ultrafast -c:a aac -b:a 128k -ac 1 -use_editlist false -ar 48000 -pix_fmt yuv420p -movflags +faststart -t 59 -y $output';
 final session = await FFmpegKit.execute(command);
 print("resize done with ${await session.getReturnCode()}");
}
</void>


However I get this error every time :

Removing the scale filter makes the function work fine, but it fails the instagram video requirements listed here.
Any help will be greatly appreciated.
