Question

当我从互联网上加载视频（10-40MB大）时，我无法提供流畅的播放体验。

我的AVPlayer要么加载整个视频然后播放，要么播放1s缓冲区，然后停止播放。

我尝试了无穷无尽的库，缓冲区观察器方法和教程。似乎没有任何帮助。

        Bitmap newImage = new Bitmap(file);
        using (Graphics gr = Graphics.FromImage(newImage))
        {
            gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
            gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
            gr.DrawImage(newImage, 0, 0, newWidth, newHeight);
        }
        pictureBox1.Image.Dispose();
        pictureBox1.Image = null;
        pictureBox1.Refresh();
       //pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
        pictureBox1.Image = newImage;
    }

自 iOS 10.x 以来，您可以进行一些缓冲设置，例如，您可以决定缓存视频所需的秒数：

    if #available(iOS 10.0, tvOS 10.0, OSX 10.12, *) {
        avPlayer?.automaticallyWaitsToMinimizeStalling = .playWhenBufferNotEmpty
        //preferredForwardBufferDuration -> default is 0, which means `AVPlayer` handle it independently, try more seconds like 5 or 10.
        playerItem.preferredForwardBufferDuration = TimeInterval(5) 
    }

AVPlayer在缓冲后停止播放视频
