How to download video iOS

Hi — I am trying to add a feature to share a video from Cloudinary through the iOS Share sheet, so it can be stored in a user's camera roll (or uploaded to Facebook, whatever).

From what I can gather, in order to make this work, I need to download the video to a file and then hand a local file URL to Apple's UIActivityViewController API. What I can't figure out is how to download the Cloudinary .mp4 file to disk.

 

I've tried three methods and they all fail:

 

1) CLDDownloader.fetchImage()

Doesn't work, because I guess this is meant only for images, not videos. I get the following error:

Error Domain=com.cloudinary.error Code=-7001 "Failed creating an image from the received data." UserInfo={NSLocalizedFailureReason=Failed creating an image from the received data.}

 

2) URLSession.downloadTask(url)

For this, I get a delegate callback of -urlSession(_:task:didCompleteWithError:), with error 'nil', but no file was ever downloaded. If I inspect the network response from Cloudinary, I see a 200, but there was never any file downloaded

 

3) AVAssetDownloadURLSession.makeAssetDownloadTask()

This returns an error, and maybe expected, as I'm handing it an mp4 URL, and I believe it's meant for HLS:

Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedDescription=The operation could not be completed, _NSURLErrorFailingURLSessionTaskErrorKey=BackgroundAVAssetDownloadTask <6CC11F75-FFA9-4A17-9F6D-DDED135EAB5A>.<1>, _NSURLErrorRelatedURLSessionTaskErrorKey=(

    "BackgroundAVAssetDownloadTask <6CC11F75-FFA9-4A17-9F6D-DDED135EAB5A>.<1>"

), NSLocalizedFailureReason=An unknown error occurred (-16090)}

 

What am I missing?

 

Or is there some other means I should be using to share videos?

Thanks,

Alan

  Hi Kevin,

  You can download your video by using the fl_attachment parameter in your URL like this https://res.cloudinary.com/demo/video/upload/fl_attachment/dog.mp4

  When the user loads this URL, he will automatically download this video.

  Regards,

  Akshay
