Questions & Answers

Hi,

I have files under sub-folders StreamingAssets folder in WebGL build, the directory and files are detecting and working fine in Editor (WebGL) when we took build and run - the files are not get detected and playing. What is the correct method to have details of directories in a path.

Thanks in advance.

Find sample test script for reference.

using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;

public class WebGLTest : MonoBehaviour
{
    public RenderHeads.Media.AVProVideo.MediaPlayer videoPlayer;
    string path;
    string mainPath;
    string result;

    DirectoryInfo dir;

    public Text pathDisplayTxt;

    void Start ()
    {
        mainPath = Path.Combine(Application.streamingAssetsPath, "Main");

        if (mainPath.Contains("://") || mainPath.Contains(":///"))
        {
            //WWW www = new WWW(mainPath);
            //yield return www;
            //result = www.text;
            //dir = new DirectoryInfo(result);
            //Debug.Log(result);
            StartCoroutine(SendRequest(mainPath));
        }
        else
        {
            dir = new DirectoryInfo(mainPath);

            if (!dir.Exists)
            {
                Debug.Log("Directory not available");
                pathDisplayTxt.text = "Directory not available : " + dir;
            }
            else
            {
                path = Application.streamingAssetsPath + "/Main/test.mp4";
                pathDisplayTxt.text = "Directory available : " + path;
                videoPlayer.OpenVideoFromFile(RenderHeads.Media.AVProVideo.MediaPlayer.FileLocation.AbsolutePathOrURL, path, true);
            }
        }
    }

    private IEnumerator SendRequest(string url)
    {
        using (UnityWebRequest request = UnityWebRequest.Get(url))
        {
            yield return request.SendWebRequest();

            dir = new DirectoryInfo(request.url);
            Debug.Log(request.url);

            if (!dir.Exists)
            {
                Debug.Log("Directory not available");
                pathDisplayTxt.text = "Directory not available WebGL : "+ request.url;
            }
            else
            {
                path = request.url + "/test.mp4";
                pathDisplayTxt.text = "Directory available WebGL : " + path;
                videoPlayer.OpenVideoFromFile(RenderHeads.Media.AVProVideo.MediaPlayer.FileLocation.AbsolutePathOrURL, path, true);
            }
        }
    }
}

You can’t access the local file system when running in the browser.

Once UnityWebRequest succeeds, you can get the downloaded asset using the downloadHandler. However, if you need to play a video you may want to consider the VideoPlayer API.
