方形视频1:1比例ffmpeg命令“；无法识别的选项'‌​；pr&x200C​；eset&x27&引用；在android中播放crop视频时未找到？

我用普通安卓摄像头成功拍摄了视频。现在我想使用ffmpeg libray命令以1:1的比例裁剪视频。但它给了我以下错误。

版本使用FFMPEG:compile'com.writingminds:FFmpegAndroid:0.3.2'

命令： -

y、/storage/emulated/0/DCIM/ZyfVideo/VID_20170916_093512.mp4、-vf，scale=720:ih*720/iw，crop=720:720，setdar=1:1，setsar=1:1，-线程，5，-预设，超快，-严格，实验，-vcodec，libx264-‌​公共关系‌​eset，超快‌​, /存储/模拟/0/DCIM/ZyfVideo/VID_20170916_093521.mp4
