Question

我正在尝试将MRC视频从Hololens流式传输到我的PC;有repo that does this，但播放媒体播放器的URI，我试图将其保存到文件中。我怎样才能做到这一点？我已经尝试过使用HttpClient，但是当我向URI发送请求时，应用程序似乎崩溃了。在我附加的链接中，有一个StartPlayback（）方法，它将Media Player的source属性设置为URI，它似乎工作正常。我尝试用以下方式修改它：

private async void StartPlayback()
    {
        Uri link = new Uri(string.Format("mrvc://{0}:{1}", this.txAddress.Text, this.txPort.Text));
        this.videoPlayer.Source = link;
        using (var client = new HttpClient())
        using (var response = await client.GetAsync(link))
        {
            // make sure our request was successful
            response.EnsureSuccessStatusCode();

            // read the filename from the Content-Disposition header
            var filename = response.Content.Headers.ContentDisposition.FileName;

            // read the downloaded file data
            var stream = await response.Content.ReadAsStreamAsync();

            // Where you want the file to be saved
            var destinationFile = Path.Combine("C:\\Users\\orsteam\\Documents", filename);

            // write the steam content into a file
            using (var fileStream = File.Create(destinationFile))
            {
                stream.CopyTo(fileStream);
            }
        }
        this.bnStart.IsEnabled = false;
        this.bnStop.IsEnabled = true;
    }

谢谢！

在Unity中，您无权访问HttpClient。您可以更改为使用WWW类。请务必检查//Inside your UITableViewCell override func prepareForReuse() { //Reset cell values here }能力。
