Trying to download an encrypted HLS stream we faced the following issue:
When we start a new download, calling resume() function of AVAssetDownloadTask, the download process gets stuck (not every time) and neither of urlSession(_:assetDownloadTask:didFinishDownloadingTo:) or urlSession(_:task:didCompleteWithError:) delegate functions (AVAssetDownloadDelegate) are getting called.
There are cases where not even the urlSession(_:assetDownloadTask:didLoad:totalTimeRangesLoaded:timeRangeExpectedToLoad:) delegate function is getting called.
Any suggestions on how to troubleshoot?
