Video Create Thumbnail From Video

Okay, I found this code written on another thread here but the thread is very old and I did not want to res. it for my questions.

Spoiler: Code

Code (CSharp):

1.     private IEnumerator GetFiles(string path)
2.         {
3.             DirectoryInfo dir = new DirectoryInfo(path);
4.             string[] extensions = new string[] { ".jpeg", ".jpg", ".png", ".avi", ".mp4", ".mov" };
5.             FileInfo[] files = dir.GetFiles("*.*", SearchOption.AllDirectories).Where(f => extensions.Contains(f.Extension.ToLower())).ToArray();
6.      
7.             int filesLenght = files.Length;
8.             for (int i = 0; i < filesLenght; i++)
9.             {
10.                 if(File.Exists(files[i].FullName))
11.                 {
12.                     if(files[i].Extension == ".jpeg" || files[i].Extension == ".jpg" || files[i].Extension == ".png")
13.                     {
14.                         GameObject go = Instantiate(Resources.Load("preview") as GameObject, content);
15.                         go.name = files[i].Name;
16.                         Texture2D tex = new Texture2D(1, 1);
17.                         byte[] bytes = File.ReadAllBytes(files[i].FullName);
18.                         tex.LoadImage(bytes);
19.                         tex = ResampleAndCrop(tex, 256, 256);
20.                         go.transform.GetChild(1).GetComponent<Image>().sprite = Sprite.Create(tex, new Rect(0, 0, tex.width, tex.height), new Vector2(0.5f, 0.5f));
21.                     }
22.                     else if(files[i].Extension == ".avi" || files[i].Extension == ".mp4" || files[i].Extension == ".mov")
23.                     {
24.                         VideoController controller = GetComponent<VideoController>();
25.                         controller.LoadVideo(files[i].FullName);
26.      
27.                         while(!controller.IsPrepared())
28.                         {
29.                             yield return null;
30.                         }
31.      
32.                         int width = controller.video.texture.width;
33.                         int height = controller.video.texture.height;
34.                         controller.video.time = 0;
35.                         RenderTexture renderTexture = new RenderTexture(width, height, 24, RenderTextureFormat.ARGB32);
36.                         renderTexture.name = files[i].Name + "Render";
37.                         controller.video.targetTexture = renderTexture;
38.                         controller.PlayVideo();
39.                         yield return new WaitForSeconds(1.5f);
40.                         Texture2D texture = new Texture2D(width, height, TextureFormat.RGBA32, false);
41.                         RenderTexture.active = controller.video.targetTexture;
42.                         texture.ReadPixels(new Rect(0, 0, width, height), 0, 0);
43.                         texture.Apply();
44.                         controller.PauseVideo();
45.                         RenderTexture.active = null;
46.                         texture = ResampleAndCrop(texture, 256, 256);
47.                         GameObject go = Instantiate(Resources.Load("preview") as GameObject, content);
48.                         go.name = files[i].Name;
49.                         go.transform.GetChild(1).GetComponent<Image>().sprite = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), new Vector2(0.5f, 0.5f));
50.                         controller.video.targetTexture = null;
51.                         Destroy(renderTexture);
52.                     }
53.                 }
54.                 yield return null;
55.             }
56.         }
57.  

I have found that this is using the Video Player Helper from this link: https://github.com/JannikLassahn/unity-videoplayer-helper.

The problem is that the code does not work because it is missing a few things now. The method LoadVideo is not in there at all and neither is the variable video. The ResampleandCrop function is a separate function that is not there also. Not sure if some of this is due to an update in the Video Player Helper VideoController.cs Code or not but I would really like help understanding how to get this working. I am new to coding with C# and have only limited programming experience.

 

Okay, it has been a while and no insight on this yet. Anyone have anything to offer? It would be greatly appreciated.
