VideoPlayer Crash on iOS Launch

Question

First off; very new to Unity; coming from an iOS / Swift background:

I have a Unity project with a video player that runs fine on a desktop environment, but when building/running for iOS, I'm getting this StackTrace and a EXC_BAD_ACCESS crash:

thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0xc38)
- frame #0: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() [inlined] IsRegistered at CallbackArray.h:223:32 [opt] frame #1: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() [inlined] IsRegistered at CallbackArray.h:154 [opt] frame #2: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() [inlined] IsRegistered at CallbackArray.h:291 [opt] frame #3: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() at VideoPlayer.cpp:1963 [opt] frame #4: 0x0000000101262eb8 ZoolikonDemo`::UpdatePlaybackParams() at VideoPlayer.cpp:2038:5 [opt] frame #5: 0x00000001012649cc ZoolikonDemo`::AwakeFromLoad() at VideoPlayer.cpp:2027:9 [opt]

This is the script I have for video playback; which is attached to the Main Camera of my Unity scene:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class PlayVideoScript : MonoBehaviour {

 public UnityEngine.Video.VideoPlayer videoPlayer;

 bool isOpen = false;

 bool buttonPressed = false;

 void OnGUI() //I think this must be used on the camera so you may have to reference a gui controller on the camera
 {
     if(isOpen) //Is it Open?
     {
         if(GUI.Button(new Rect(Screen.width/2, Screen.height/2, 200, 200), "GREEN")) //Display and use the Yes button
         {
             Debug.Log("Yes");
             videoPlayer.Play();
             isOpen = false;
             buttonPressed = true;
         }
         if(GUI.Button(new Rect(Screen.width/3, Screen.height/2, 200, 200), "RED")) //Display and use the No button
         {
             Debug.Log("No");
             isOpen = false;
             buttonPressed = true;

         }
     }
 }



 // Start is called before the first frame update
 void Start()
 {

     // Will attach a VideoPlayer to the main camera.
     GameObject camera = GameObject.Find("Main Camera");

     // VideoPlayer automatically targets the camera backplane when it is added
     // to a camera object, no need to change videoPlayer.targetCamera.
     videoPlayer = camera.AddComponent<UnityEngine.Video.VideoPlayer>();

     // Play on awake defaults to true. Set it to false to avoid the url set
     // below to auto-start playback since we're in Start().
     videoPlayer.playOnAwake = false;

     // By default, VideoPlayers added to a camera will use the far plane.
     // Let's target the near plane instead.
     videoPlayer.renderMode = UnityEngine.Video.VideoRenderMode.CameraNearPlane;

     // This will cause our Scene to be visible through the video being played.
     videoPlayer.targetCameraAlpha = 0.5F;

     // Set the video to play. URL supports local absolute or relative paths.
     // Here, using absolute.
     videoPlayer.url = "Assets/Zoolikon.mp4";

     // Skip the first 100 frames.
     videoPlayer.frame = 100;

     // Restart from beginning when done.
     videoPlayer.isLooping = false;

     // Each time we reach the end, we slow down the playback by a factor of 10.
     //videoPlayer.loopPointReached += EndReached;

     // Start playback. This means the VideoPlayer may have to prepare (reserve
     // resources, pre-load a few frames, etc.). To better control the delays
     // associated with this preparation one can use videoPlayer.Prepare() along with
     // its prepareCompleted event.
     videoPlayer.Play();
 }

 // Update is called once per frame
 void Update()
 {
     print(videoPlayer.time);

     print(videoPlayer.time);
     if (videoPlayer.time >= 5.0 && buttonPressed == false) {
         print("paused;");
         videoPlayer.Pause();
         isOpen = true;   //Set the buttons to appear
     }

 }

}

,First off, disclaimer; I'm very new to using Unity; coming form an iOS/Swift background...

I have a Unity project with a video player that runs fine on a desktop environment, but when building/running for iOS, I'm getting this StackTrace; and really not sure exactly what seems to be going wrong or where it's happening...

thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0xc38)
frame #0: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() [inlined] IsRegistered at CallbackArray.h:223:32 [opt] frame #1: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() [inlined] IsRegistered at CallbackArray.h:154 [opt] frame #2: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() [inlined] IsRegistered at CallbackArray.h:291 [opt] frame #3: 0x000000010126252c ZoolikonDemo`::SetCameraEmitGeometryCallback() at VideoPlayer.cpp:1963 [opt] frame #4: 0x0000000101262eb8 ZoolikonDemo`::UpdatePlaybackParams() at VideoPlayer.cpp:2038:5 [opt] frame #5: 0x00000001012649cc ZoolikonDemo`::AwakeFromLoad() at VideoPlayer.cpp:2027:9 [opt]

Below is my script for playing a video with a player that's attached to the MainCamera:

public class PlayVideoScript : MonoBehaviour {

 public UnityEngine.Video.VideoPlayer videoPlayer;

 bool isOpen = false;

 bool buttonPressed = false;

 void OnGUI() //I think this must be used on the camera so you may have to reference a gui controller on the camera
 {
     if(isOpen) //Is it Open?
     {
         if(GUI.Button(new Rect(Screen.width/2, Screen.height/2, 200, 200), "GREEN")) //Display and use the Yes button
         {
             Debug.Log("Yes");
             videoPlayer.Play();
             isOpen = false;
             buttonPressed = true;
         }
         if(GUI.Button(new Rect(Screen.width/3, Screen.height/2, 200, 200), "RED")) //Display and use the No button
         {
             Debug.Log("No");
             isOpen = false;
             buttonPressed = true;

         }
     }
 }



 // Start is called before the first frame update
 void Start()
 {

     // Will attach a VideoPlayer to the main camera.
     GameObject camera = GameObject.Find("Main Camera");

     // VideoPlayer automatically targets the camera backplane when it is added
     // to a camera object, no need to change videoPlayer.targetCamera.
     videoPlayer = camera.AddComponent<UnityEngine.Video.VideoPlayer>();

     // Play on awake defaults to true. Set it to false to avoid the url set
     // below to auto-start playback since we're in Start().
     videoPlayer.playOnAwake = false;

     // By default, VideoPlayers added to a camera will use the far plane.
     // Let's target the near plane instead.
     videoPlayer.renderMode = UnityEngine.Video.VideoRenderMode.CameraNearPlane;

     // This will cause our Scene to be visible through the video being played.
     videoPlayer.targetCameraAlpha = 0.5F;

     // Set the video to play. URL supports local absolute or relative paths.
     // Here, using absolute.
     videoPlayer.url = "Assets/Zoolikon.mp4";

     // Skip the first 100 frames.
     videoPlayer.frame = 100;

     // Restart from beginning when done.
     videoPlayer.isLooping = false;

     // Each time we reach the end, we slow down the playback by a factor of 10.
     //videoPlayer.loopPointReached += EndReached;

     // Start playback. This means the VideoPlayer may have to prepare (reserve
     // resources, pre-load a few frames, etc.). To better control the delays
     // associated with this preparation one can use videoPlayer.Prepare() along with
     // its prepareCompleted event.
     videoPlayer.Play();
 }

 // Update is called once per frame
 void Update()
 {
     print(videoPlayer.time);

     print(videoPlayer.time);
     if (videoPlayer.time >= 5.0 && buttonPressed == false) {
         print("paused;");
         videoPlayer.Pause();
         isOpen = true;   //Set the buttons to appear
     }

 }

}
