MovieTexture - Black Video with Audio

Hey guys,

I ran into an issue today where i was trying to play back a MovieTexture with audio. The video wouldn't play back showing only a black screen but the audio would play back. The video would play back in VLC fine and Windows Media Player.

My quick fix was to create the videos and audio files separately and everything works fine. Although, i was curious as to why it wouldn't work?

EDIT: I just realized it may be how Unity converts the file. The file size is 2.8kb when I import it with audio instead of 5mb without audio.

The video file was .mp4 and the quality settings in Unity were default.

Here is my script i was using:

 using UnityEngine;
 using System.Collections;
 
 public class AutoPlayVideo : MonoBehaviour
 {
     public MovieTexture objectVideo;
     
     public bool videoHasAudio = false;
     
     public AudioClip audioClip;
       
     AudioSource audiodata;
     
     void Awake()
     {
         transform.renderer.material.mainTexture = objectVideo;
         objectVideo.loop = true;
         
         if(videoHasAudio)
         {
                audiodata = GetComponent<AudioSource>();
               audiodata.clip = audioClip;    
             audiodata.playOnAwake = false;
             audiodata.loop = true;
         }
     }
     
     void OnEnable()
     {
         objectVideo.Play ();
         if(videoHasAudio)audiodata.Play ();
     }
     
     void Update()
     {
         //Debug.Log (""+objectVideo.isPlaying);    
     }
     
     void OnDisable()
     {
         objectVideo.Stop ();
         if(videoHasAudio)audiodata.Stop();
     }
 }
