Question

早上好

我试图创建一种方法，该方法可从www URL检索视频数据，然后通过单击Unity中的按钮以定义的位置和大小显示它。

但是，当我开始该过程时，视频不起作用也不做任何事情。在分析了代码之后，我注意到IsPrepared（）方法永无止境，它永远卡在那里。我将代码附加在此注释的下面。

public IEnumerator CreateVideo(WWW www, RawImage image)
    {
        Debug.Log("Video");
        yield return www;
        //Set Size & Position
        image.GetComponent<RectTransform>().sizeDelta = new Vector2(0.5f, 0.5f);
        image.GetComponent<RectTransform>().position = new Vector3(0.5f, 0.5f, 10.0f);

        //Add VideoPlayer to the GameObject
        //videoPlayer = image.GetComponent<VideoPlayer>();

        //Add AudioSource
        // audioSource = image.GetComponent<AudioSource>();

        //Add VideoPlayer to the GameObject
        VideoPlayer videoPlayer = image.GetComponent<VideoPlayer>();
        
        //Add AudioSource
       AudioSource audioSource = image.GetComponent<AudioSource>();
        Debug.Log(audioSource);
        //Disable Play on Awake for both Video and Audio
        videoPlayer.playOnAwake = true;
        audioSource.playOnAwake = true;



        //We want to play from url
        videoPlayer.source = VideoSource.Url;
        videoPlayer.url = www.url;
       

        //Set Audio Output to AudioSource
        videoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;
        videoPlayer.controlledAudioTrackCount = 1;

        //Assign the Audio from Video to AudioSource to be played
        videoPlayer.EnableAudioTrack(0, true);
        videoPlayer.SetTargetAudioSource(0, audioSource);

        //Set video To Play then prepare Audio to prevent Buffering
        videoPlayer.Prepare();

        WaitForSeconds waitTime = new WaitForSeconds(5);
        while (!videoPlayer.isPrepared)
        {
            Debug.Log("Preparing Video");
            //Prepare/Wait for 5 sceonds only
            yield return waitTime;
            //Break out of the while loop after 5 seconds wait
            break;
        }

        //Assign the Texture from Video to RawImage to be displayed
        image.texture = videoPlayer.texture;

        //Play Video
        videoPlayer.Play();
        Debug.Log("Playing Video");

        //Play Sound
        try
        {
            audioSource.Play();

        }catch (System.Exception e)
        {
            Debug.Log(string.Format("Exception thrown whilst getting audio clip {0} ", e.Message));
        }
            
        

        
        while (videoPlayer.isPlaying)
        {
            Debug.LogWarning("Video Time: " + Mathf.FloorToInt((float)videoPlayer.time));
            yield return null;
        }

        Debug.Log("Done Playing Video");
    }

RawImage对象保存在Prefab文件夹中（将来我想实例化该对象），其中包括几个组件，如VideoPlayer，AudioSource，Mesh Renderer（如果需要）和透明纹理。

对这个问题的可能解决方案有任何想法吗？

谢谢！
