我开始尝试新的Unity beta 5.6视频播放器。我制作了一个媒体播放器来循环RawImage上的文件夹（url）中的图像和视频。
当我向文件夹中添加较大的视频文件（预告片）时，播放器很快就会在视频结束后卡住并且不会离开while (videoPlayer.isPlaying)循环。同时渲染完全停止在探查器工具中。小而且不会发生这种情况。更短的视频剪辑。
音频也有一个小错误。音频不会在第一个视频文件的第一个循环播放。之后就可以了。
我是否犯了一些错误，或者这可能是测试版中的错误？我只测试了.mp4视频。
编辑：似乎现在解决方法是在videoPlayer.isLooping = true;命令后添加videoPlayer.Play();。代码已更新。
