我已使用以下命令从默认相机最初捕获的裁剪视频。但是当我执行命令时，它给出了以下错误。

 final String[] cmd={"-i", "/storage/emulated/0/DCIM/ZyfVideo/VID_20170914_153804.mp4","-s", "480x480" ,"-vf" ,"crop=480:480","setdar=1:1","setsar=1:1 ","/storage/emulated/0/Movies/SpoofApp/VDO_20170914_153811.mp4"};

我对 ffmpeg 没有这样的想法，但我可以告诉你易于使用的 jCodec lib。

访问 jcodec.org。

如果要裁剪视频，则必须在 android 或 java 中执行以下步骤。1. 从 jcodec 的实用方法中获取框架。2. 使用 Bitmap 辅助类进行裁剪。3.使用jcodec utilty函数打包成mp4格式。

如果您无法做到这一点，请给我写一封邮件 sunilgupta3443@gmail.com

我将帮助您在 android 中制作裁剪视频应用程序。

谢谢
