Video Problem videoPlayer and Windows 7

Hi all!

I've a plane with a videoPlayer component and I load the video from streamingAssets with a script that I found here in this forum.
All works well but if I try to run this with windows 7, some video doesn't play.

This is the script:

Code (CSharp):

1. IEnumerator playVideo()
2.     {
3.         try{
4.             Destroy(videoPlayer);
5.             Destroy(audioSource);
6.         }catch{
7.  
8.         }
9.           //Add VideoPlayer to the GameObject
10.         videoPlayer = gameObject.AddComponent<VideoPlayer>();
11.         //Add AudioSource
12.         audioSource = gameObject.AddComponent<AudioSource>();
13.  
14.         /*videoPlayer = GetComponent<VideoPlayer> ();
15.         audioSource = GetComponent<AudioSource> ();*/
16.         //Disable Play on Awake for both Video and Audio
17.         videoPlayer.playOnAwake = false;
18.         audioSource.playOnAwake = false;
19.         audioSource.Pause();
20.         //We want to play from video clip not from url
21.        
22.         videoPlayer.source = VideoSource.VideoClip;
23.         // Vide clip from Url
24.         videoPlayer.source = VideoSource.Url;
25.         videoPlayer.url = Application.streamingAssetsPath +"/"+ System.IO.File.ReadAllText (Application.dataPath + "/Resources/videoSelected.txt");
26.         //Set Audio Output to AudioSource
27.         videoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;
28.         //Assign the Audio from Video to AudioSource to be played
29.         videoPlayer.EnableAudioTrack(0, true);
30.         videoPlayer.SetTargetAudioSource(0, audioSource);
31.         //Set video To Play then prepare Audio to prevent Buffering
32.         videoPlayer.clip = videoToPlay;
33.         videoPlayer.Prepare();
34.         //Wait until video is prepared
35.         WaitForSeconds waitTime = new WaitForSeconds(1);
36.         while (!videoPlayer.isPrepared)
37.         {
38.             Debug.Log("Preparing Video");
39.             //Prepare/Wait for 5 sceonds only
40.             yield return waitTime;
41.             //Break out of the while loop after 5 seconds wait
42.             break;
43.         }
44.         Debug.Log("Done Preparing Video");
45.         //Assign the Texture from Video to RawImage to be displayed
46.         image.texture = videoPlayer.texture;
47.         //Play Video
48.         videoPlayer.Play();
49.         //Play Sound
50.         audioSource.Play();
51.         Debug.Log("Playing Video");
52.         while (videoPlayer.isPlaying)
53.         {
54.             Debug.LogWarning("Video Time: " + Mathf.FloorToInt((float)videoPlayer.time));
55.             yield return null;
56.         }
57.         Debug.Log("Done Playing Video");
58.  
59.     }

The video that I need now is 500Mb+, has a width of 3000px and it's an mp4 (H264). It works in windows 10 and doesn't in windows 7. Any Idea?

I tried other videos. With lighter(50-100Mb) videos works well but with a 4K video I've the same problem as before.

 

I have a similar issue on Win7 and trying to force Codec to VP8 hangs Unity.
