iOS AVAssetDownloadURLSession Wrapper

AssetDownloadWrapper

A wrapper to download videos using AVAssetDownloadURLSession.

About

This is the library that wraps the function of AVAssetDownloadURLSession. Download the video and cache it to local storage.

How to implement

• Download the video

    let url = URL(string: "https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8")!
    let urlAsset = AVURLAsset(url: url)
    let asset = AssetWrapper(urlAsset: urlAsset, assetTitle: "hoge")
    AssetDownloadManager.shared.downloadStream(for: asset) { (result) in
      switch result {
        case .success(let response):
        print(response)
        case .failure(let error):
        print(error)
      }
    }

• Load local cache

    guard let arg = AssetDownloadManager.shared.retrieveLocalAsset(with: "hoge") else {
         return
     }
     let vc = AVPlayerViewController()
     let item = AVPlayerItem(asset: arg.0.urlAsset)
     player.replaceCurrentItem(with: item)
     vc.player = player
