unity使用easyar录屏更换视频保存路径

Question

当前默认是保存在Android/data/包名/files
又尝试更改路径到/storage/dmic
但是会报错（是因为这个路径算外部路径吗）
不知道怎么操作。希望是保存的录屏在系统相册视频中能够查看

首先，您需要确保您的设备有拓展存储卡，并且您有权在其中创建文件。 具体的步骤如下：

打开 Unity 的项目，并创建一个新的 C# 脚本，命名为“ScreenRecorder”。

在 ScreenRecorder 脚本中，添加以下代码：

using EasyAR;
using System.IO;
using UnityEngine;

public class ScreenRecorder : MonoBehaviour
{
    public string folderName = "EasyAR Screen Recordings";
    public string fileName = "EasyARScreenRecording";
    public int recordingWidth = 720;
    public int recordingHeight = 1280;

    private ScreenRecorderBase recorderBase;
    private string rootPath;

    private void Start()
    {
        rootPath = Path.Combine(Application.persistentDataPath, folderName);
        recorderBase = GetComponent<ScreenRecorderBase>();
        recorderBase.RecordingWidth = recordingWidth;
        recorderBase.RecordingHeight = recordingHeight;
    }

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.R))
        {
            if (recorderBase.IsRecording)
            {
                recorderBase.StopRecording();
                string filePath = Path.Combine(rootPath, fileName + ".mp4");
                Debug.Log("Screen recording saved to: " + filePath);

                // add code here to copy the recording to a public folder
                // ...
            }
            else
            {
                recorderBase.StartRecording();
                Debug.Log("Screen recording started");
            }
        }
    }
}

在新的脚本中，修改 rootPath 变量的值为所需的文件夹路径，例如：
rootPath = Path.Combine("/storage/emulated/0/DCIM", folderName);

4、在 Update 函数中，添加以下代码：

if (recorderBase.IsRecording)
{
    recorderBase.StopRecording();
    string filePath = Path.Combine(rootPath, fileName + ".mp4");
    Debug.Log("Screen recording saved to: " + filePath);

    // copy the recording to a public folder
    string publicFilePath = Path.Combine("/storage/emulated/0/DCIM/Camera", fileName + ".mp4");
    File.Copy(filePath, publicFilePath, true);

    // refresh the Android Gallery to show the newly added file
    AndroidJavaClass class
