mp4解码成yuv找不到文件

[mrqinshou]

请问这个支持解码成 yuv 吗?我使用如下命令想将 mp4 文件解码成 yuv
ffmpeg -y -i /storage/emulated/0/big_buck_bunny.mp4 /storage/emulated/0/big_buck_bunny.yuv
代码是这样的:

RxFFmpegInvoke.getInstance().runCommandAsync(new String[]{"ffmpeg", "-y", "-i", "/storage/emulated/0/big_buck_bunny.mp4", "/storage/emulated/0/big_buck_bunny.yuv"}, new RxFFmpegInvoke.IFFmpegListener() {
@OverRide
public void onFinish() {
Log.i(TAG, "onFinish: ");
}

@Override
public void onProgress(int progress, long progressTime) {
    Log.i(TAG, "onProgress: " + "progress--->" + progress + ",progressTime--->" + progressTime);
}

@Override
public void onCancel() {
    Log.i(TAG, "onCancel: ");
}

@Override
public void onError(String message) {
    Log.i(TAG, "onError: " + message);
}

});

但是提示找不到文件,我并没有预先创建 big_buck_bunny.yuv,存储权限也是有的

ffmpeg -y -i /storage/emulated/0/1/input.mp4 -preset superfast /storage/emulated/0/1/result.yuv 试了一下可以的。看看是不是存储权限的问题，或者在demo apk上试试
