Need help with issues using the VideoPlayer released in Unity 5.6

The goal for what I am looking to do is the following:

1) I need to load video from an URL on iOS using Prepare(). Once prepared, I will enable a play button for the user to play video on iOS

2) I need audio to play from the video.

3) I need to be able to rotate the video and resize based on device orientation.

After several tries, I can't seem to get consistent behavior from the VideoPlayer in any way. My current state of my script is that the video plays automatically after my video fires the prepared event, regardless if I call play on the video player component or not. Also audio will not play if I set the audio to Direct or AudioSource. I currently am using AudioSource as I read that it should always work, which it doesn't.

So I do not want to the video to play automatically but just enable a "Play" button, and I want audio to play. I do have fullscreen video with rotation working however. My current setup in my screen is I have a Canvas, with a RawImage component as its child. I attached my script TestVideo.cs to the RawImage component. The RectTransform of the RawImage is set to Middle Center with a width and height of 10. This gets resized with my methods depending upon device orientation and video orientation.

I attach the VideoPlayer component and the AudioPlayer Component in my TestVideo.cs script at runtime.

Here is the TestVideo.cs for reference:

 public class TestVideo : MonoBehaviour {
 
         private bool _rotatedLeftBol;
         private bool _rotatedRightBol;

         private Vector2 _refResV2 = new Vector2(320f,550f);
 
         private bool _isVideoLandscapeBol;
         AudioSource _audioSource;

             _audioSource = _gameObject.AddComponent<AudioSource>();
 
             //Disable Play on Awake for both Video and Audio
             _vidPlayer.playOnAwake = false;
             _audioSource.playOnAwake = false;
 
             //Set Audio Output to AudioSource
             _vidPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;
 
             //Assign the Audio from Video to AudioSource to be played
             _vidPlayer.EnableAudioTrack(0, true);
             _vidPlayer.SetTargetAudioSource(0, _audioSource);
             _vidPlayer.prepareCompleted += Prepared;
             _vidPlayer.Prepare();

             if (_isVideoLandscapeBol)
             {
                  __videoWidthFlt = ((float)_vidPlayer.texture.width >= _refResV2.x) ? _refResV2.x : (float)_vidPlayer.texture.width;
             }

         {
             LeanTween.rotateLocal(gameObject, __v3, 0.25f).setEase(LeanTweenType.easeInOutCirc);
         }
 }

So I created two more tests. The first one, I can get audio to play by creating a RawImage Component on the canvas and adding the VideoComponent to the RawImage component in the Editor instead of at runtime. But the video won't play nor will the prepareCompleted event fire at all. This version I can get audio to play using Direct mode or the AudioSource mode by adding an audio source to the component and referencing that in the VideoPlayer. But as I stated before no video.

The second test, I can get both video and audio working but I cannot use the UGUI system. I have game object with a quad mesh and a meshRenderer on it. I set the renderMode in VideoPlayer to MaterialOverride and reference the attached MeshRenderer. But even with this version there are two issues:

1) prepareComplete still does not fire so I have to set video to play onAwake which I do not want and 2) This is not using the UGUI system which is extremely ideal for me by how I have my project setup.

I know this is long but I am trying to put all possibilities out there in case I forgot something or am doing something completely stupid. I feel though that the VideoComponent is still very buggy as like the question states, I can't get any consistency out of it depending on how it's implemented even though I am using the BuckBunny video for all of my tests.
