我正在使用https://github.com/WritingMinds/ffmpeg-android-java使用以下命令裁剪视频：
execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out);
我遇到了很多相同的问题,却找不到所需的解决方案.我还尝试了以下通过搜索发现的命令：
execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out);
private void execFFmpegCommand(final String command) {
try {
ffmpeg.execute(new String[]{command}, new ExecuteBinaryResponseHandler() {
@Override
public void onFailure(String s) {
Log.d(TAG, "Failed with output : " + s);
progressDialog.dismiss();
}
@Override
public void onSuccess(String s) {
Log.d(TAG, "SUCCESS with output : " + s);
}
@Override
public void onProgress(String s) {
Log.d(TAG, "Started command : ffmpeg " + command);
Log.d(TAG, "progress : " + s);
}
@Override
public void onStart() {
Log.d(TAG, "Started command : ffmpeg " + command);
progressDialog.show();
}
@Override
public void onFinish() {
Log.d(TAG, "Finished command : ffmpeg " + command);
progressDialog.dismiss();
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// do nothing for Now
}
}
LogCat是：

解决方法:
我终于想通了
该命令应作为数组传递.
String[] cmd = {"-i", in, "-filter:v", "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100, "-c:a", "copy", out};
execFFmpegCommand(cmd);
