Unity/Videoplayer - Game sometimes crash if I load next video - ios

Question

I use Video Player which attached 3D game object. This game object contain "Mesh Renderer" component too. Video Player Renderer-> this game object.
I try many method, but always crash game.
I try use in Update: Videoplayer().isplaying if false, then I load from Resources next video and play, but not working. (Unity Editor working fine, but in iPhone sometimes crash game.)
Then I try other method..
But sometimes crash too..
Okey, I think maybe loading and start playing too fast, maybe this cause the crash.
Then I try use Ienumerator waitforsecond every step, for debugging I set it 5 seconds.
I try first set video player.clip = null, maybe this is the problem.. But not..
Now the code:
void Start()
{
index = 0;
videoPlayer = gameObject.GetComponent<VideoPlayer>();
videoPlayer.loopPointReached += CheckOver;
}
IEnumerator Waitforseconds()
{
Debug.Log("Waitforseconds start");
videoPlayer.clip = null;
Debug.Log("Videoplayer clip null);
yield return new WaitForSeconds(5);
videoPlayer.clip = theVideo;
Debug.Log("Videoplayer set the video");
yield return new WaitForSeconds(5);
Debug.Log("Next play video player");
videoPlayer.Play();
Debug.Log("Play video player");
isPlaying = true;
}
void CheckOver(UnityEngine.Video.VideoPlayer vp)
{
Debug.Log("Checkover");
index += 1;
if (index >= videos.Length)
{
index = 0;
}
theVideo = videos[index];
Debug.Log("Set the video");
StartCoroutine(Waitforseconds());
}
The videos size 5-10 MB and 10-60 seconds.
The result: Unity Editor working good, I build to iOS and sometimes crash the game if I play next video (iPhone 12 Pro Max, supposedly the fastest smartphone chip, so if that doesn't work, there's a big problem..)
Debug:
I get last Debug.log before the game crash:
"Videoplayer clip null"
So I think the game crash here: videoPlayer.clip = theVideo;
But only iOS! Unity editor working good.
Xcode error:
I try find solution in google, but I can't find..
Maybe memory error? should I somehow delete the previous video from memory?
Or how can I solve this problem? Please help me.
Thank you very much!
EDIT: I see the problem is Audio. (Audio Output mode: Audio Source, this component attached to same gameobject. So same game object contain audio source and video player.) If I set Audio Output mode to "none", then game not crash, workin good. So the problem when "PrepareAudioTap". How can I solve this problem?

Answer 1

Solved!
I change Video Player component "Audio Output mode": Audio Source to Direct.
Then not crash game.
But I would like to use Audio Source, because I need 3D Sound. (not important, I'm glad it works, but if you have idea how to work with 3D sound, I would be glad.)
Thanks!
