I am trying to play remote media using
MediaSource created from
CreateFromDownloadOperation, with the idea that media would start playing as soon as some meaningful data is downloaded through
DownloadOperation. Also, I would be able to save it locally for the next time.
It was mentioned in the forum post sometime back here at https://social.msdn.microsoft.com/Forums/en-US/37b2650c-4d81-4448-91ea-c57be33d4c74/rs41803uwpc-media-player-mediasource-createfromdownloadoperation-deleted-download-files?forum=wpdevelop
Breeze asked me to take a look at this. Is there a particular reason that you are using the background download playback functionality in your app?
The intent of this functionality is to allow for immediate playback of an audio or video file while also caching the file locally for offline playback at a later date.
However, what I am finding is that the media does not start playing till the file is completely downloaded. I am on 1803, with Target set to 1903 and min target of 1803. Here is basics of my code
var destinationFile = await ApplicationData.Current.LocalFolder.CreateFileAsync(
var download = new BackgroundDownloader().CreateDownload(url, destinationFile);
download.IsRandomAccessRequired = true;
var task = Task.Run(async ()=> await download.StartAsync());
mediaPlayer.Source = MediaSource.CreateFromDownloadOperation(download);
However if I create mediaSource from
MediaSource.CreateFromUri(), it starts playing almost immediately.
