Unity:视频文件的音频与Unity一起播放时会断断续续



我在Unity编辑器或Unity应用程序(Windows独立应用程序(上播放一些视频时遇到问题。视频文件的音频断断续续。

如果我使用任何玩家在Windows上播放录制的视频文件,则不会出现问题。

在处理此问题之后,我想我弄清楚了问题:录制视频的音频持续时间大于视频的持续时间。

您可以看到普通视频的详细信息和录制的视频。

普通视频详细信息:https://drive.google.com/file/d/1qzksr-fb2ohb2w1xwoozum0xt3acqzm4/view?usp = sharing

记录的视频详细信息:https://drive.google.com/file/d/1jpr2ijwtibylswh7itvfm0nhoprarnm4/view?usp = sharing

我的问题是两个部分:

1-持续时间的差异可以解决这个问题。

2-如何解决这个问题?

private IEnumerator PlayVideo(string filePath)
{
    //Add VideoPlayer to the GameObject
    _videoPlayer = gameObject.AddComponent<VideoPlayer>();
    //Add AudioSource
    _audioSource = gameObject.AddComponent<AudioSource>();
    //Disable Play on Awake for both Video and Audio
    _videoPlayer.playOnAwake = false;
    _audioSource.playOnAwake = false;
    _audioSource.Pause();
    //We want to play from video clip not from url
    //videoPlayer.source = VideoSource.VideoClip;
    // Vide clip from Url
    _videoPlayer.source = VideoSource.Url;
    _videoPlayer.url = filePath;

    //Set Audio Output to AudioSource
    _videoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;
    //Assign the Audio from Video to AudioSource to be played
    _videoPlayer.controlledAudioTrackCount = 1;
    _videoPlayer.EnableAudioTrack(0, true);
    _videoPlayer.SetTargetAudioSource(0, _audioSource);
    //Set video To Play then prepare Audio to prevent Buffering
    //videoPlayer.clip = myVideoClip;
    _videoPlayer.Prepare();
    //Wait until video is prepared
    WaitForSeconds waitTime = new WaitForSeconds(1);
    _retryCount = 0;
    while (!_videoPlayer.isPrepared)
    {
        Debug.Log("Preparing Video");
        //Prepare/Wait for 15 sceonds only
        yield return waitTime;
        _retryCount++;
        if (_retryCount >= _maximumRetries)
        {
            break;
        }
    }
    _vidFrameLength = (int)_videoPlayer.frameCount;
    ProgressBar.maxValue = _vidFrameLength;
    Debug.Log("Done Preparing Video");
    VideoPlayerImage.texture = _videoPlayer.texture;
    _videoPlayer.Play();
    _audioSource.Play();
    ClipLength.text = StringHelper.ToTime((float)_videoPlayer.frameCount / _videoPlayer.frameRate, TimePreviewer.Minutes);
    while (_videoPlayer.isPlaying)
    {
        yield return null;
    }
}

假设您正在使用VideoPlayer组件尝试更改音频输出模式从AudioSource到Direct Vise Verna,以查看是否会改变某物。

目前,我在Unity商店中发现了2个视频库,它们播放了无聊的视频而没有问题。

我正在使用其中一个,直到Unity解决了有关播放可变帧速率视频的问题。

我知道这不是解决问题的解决方案,但是直到任何人对问题给出一个很好的答案,我将使用此问题。

尝试将iuiousource加载类型修改为"蒸"。
