通过Xamarin将视频上传到Azure存储

我正在尝试将视频文件上传到我的Azure存储帐户.我已经将其与图像配合使用，但是尝试查看上传的视频会显示消息不支持视频格式或MIME类型".视频格式为mp4.

我使用以下代码进行上传:

public async Task UploadVideo(Stream video, string path) { var container = GetContainer("videos"); // Creates the container if it does not exist await CreateContainer(container); //Gets the file extension string lastPart = path.Split('.').Last(); // Uploads the video to the blob storage CloudBlockBlob videoBlob = container.GetBlockBlobReference(path); videoBlob.Properties.ContentType = "video/" + lastPart; await videoBlob.UploadFromStreamAsync(video); }

我做错什么了吗?

谢谢

这是我用来在手机上捕获视频的代码:

private async Task TakeVideoButton_Clicked(object sender, EventArgs e) { if (!CrossMedia.Current.IsCameraAvailable || !CrossMedia.Current.IsTakeVideoSupported) { await DisplayAlert("No Camera", ":( No camera avaialble.", "OK"); return; } mediaFile = await CrossMedia.Current.TakeVideoAsync(new Plugin.Media.Abstractions.StoreVideoOptions { Name = "video.mp4", Directory = "DefaultVideos", }); if (mediaFile == null) return; await DisplayAlert("Video Recorded", "Location: " + mediaFile.Path, "OK"); videoStream = mediaFile.GetStream(); file.Dispose(); }

解决方案

我只是在手机上而不是在模拟器上测试了它，并且在那儿工作得很好，所以我将假定它纯粹是与模拟器有关的问题. >

I'm trying to upload a video file to my Azure Storage account. I've got it working with images, however trying to view an uploaded video gives the message "Video format or MIME-type is not supported". The video format is mp4.

I use the following code to upload:

public async Task UploadVideo(Stream video, string path) { var container = GetContainer("videos"); // Creates the container if it does not exist await CreateContainer(container); //Gets the file extension string lastPart = path.Split('.').Last(); // Uploads the video to the blob storage CloudBlockBlob videoBlob = container.GetBlockBlobReference(path); videoBlob.Properties.ContentType = "video/" + lastPart; await videoBlob.UploadFromStreamAsync(video); }

Am I doing something wrong?

Thanks

Edit:

Here's the code I use to capture video on the phone:

private async Task TakeVideoButton_Clicked(object sender, EventArgs e) { if (!CrossMedia.Current.IsCameraAvailable || !CrossMedia.Current.IsTakeVideoSupported) { await DisplayAlert("No Camera", ":( No camera avaialble.", "OK"); return; } mediaFile = await CrossMedia.Current.TakeVideoAsync(new Plugin.Media.Abstractions.StoreVideoOptions { Name = "video.mp4", Directory = "DefaultVideos", }); if (mediaFile == null) return; await DisplayAlert("Video Recorded", "Location: " + mediaFile.Path, "OK"); videoStream = mediaFile.GetStream(); file.Dispose(); }

解决方案

I just tested this on my phone instead of my emulator and it worked perfectly there, so I'm going to assume it's purely a emulator related issue.
