Question

我想在Unity中的Sphere中放映电影。那很酷，它可以工作，但是没有声音。首先，我为自己的领域构建了一种新材料。那就是着色器（材料）的代码：

Shader "Flip Normals" {
	Properties{
		_MainTex("Base (RGB)", 2D) = "white" {}
	}
		SubShader{

		Tags{ "RenderType" = "Opaque" }

		Cull Front

		CGPROGRAM

#pragma surface surf Lambert vertex:vert
		sampler2D _MainTex;

	struct Input {
		float2 uv_MainTex;
		float4 color : COLOR;
	};


	void vert(inout appdata_full v)
	{

		v.normal.xyz = v.normal * -1;
	}

	void surf(Input IN, inout SurfaceOutput o) {
		fixed3 result = tex2D(_MainTex, IN.uv_MainTex);
		o.Albedo = result.rgb;
		o.Alpha = 1;
	}

	ENDCG

	}

		Fallback "Diffuse"
}

此后，我为播放器编写了一个脚本。它工作正常，但是没有声音...

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Video;
using UnityEngine.Playables;



public class sphereStartTest : MonoBehaviour {

    public VideoClip videoToPlay;

    //video
    private VideoPlayer videoPlayer;
    private VideoSource videoSource;

    //audio
    private AudioSource audioSource;


	// Use this for initialization
	void Start () {
        Application.runInBackground = true;
        StartCoroutine(playVideo());
	}
	
    IEnumerator playVideo(){
        //add VideoPlayer to the GameObjekt
        videoPlayer = gameObject.AddComponent<VideoPlayer>();

        //add AudioSource
        audioSource = gameObject.AddComponent<AudioSource>();

        //disable Play on Awayke for Video and Audio
        videoPlayer.playOnAwake = true;
        audioSource.playOnAwake = true;
        Debug.Log("DEBUG: source Loading");

        videoPlayer.source = VideoSource.VideoClip;

        //set video to Play then prepare Audio to prevent Buffering
        videoPlayer.clip = videoToPlay;
        videoPlayer.Prepare();
        
        Debug.Log("DEBUG: Done Preparing Video");

        //set Audio Output to AudioSource
        videoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;

        //assign the Audio from Video to AudioSource to be played
        videoPlayer.EnableAudioTrack(0, true);
        videoPlayer.SetTargetAudioSource(0, audioSource);

        //wait until video id prepared
        while (!videoPlayer.isPrepared)
        {
            Debug.Log("DEBUG: Preparing Video");
            yield return null;
        }

        //play Video
        videoPlayer.Play();

        //play Audio
        audioSource.Play();
    }
}

最后一个脚本是切换场景脚本。这很好。

using UnityEngine;
using UnityEngine.Video;
using UnityEngine.SceneManagement;

public class switchScene : MonoBehaviour {

    public VideoPlayer VideoPlayer;
    public string SceneName;

    // Use this for initialization
    void Start () {
        VideoPlayer.loopPointReached += loadScene;
		
	}

    //load the Scene
    void loadScene(VideoPlayer vp)
    {
        SceneManager.LoadScene(SceneName);
    }
}

该项目针对Android进行了优化。我使用了.mp4文件（未作为电影纹理导入）。有谁知道我如何将声音从.mp4文件发送到我的Projekt。 The "Video Player" at sphere got an Audio Source, but the AudioSource at my Sphere doesn't got an AudioClip.
