Windows Store App play any files

Question

I have list of files

1. D:\\Videos\\Video_1.mp4

2. \\\\SOME-NETWORK-PC\\Shared\\Video_2.mp4

   ...

I need play files in MediaElement.

MediaElement.Source = new Uri(url from list);
MediaElement.Play();

but I have this error:

MF_MEDIA_ENGINE_ERR_SRC_NOT_SUPPORTED

Default installed in windows 10 "Movies & TV" - can play video from this list.

Answer 1

1. In Windows Store App user must allow access to file/folder with FileOpenPicker/FolderPicker

2. After getting StorageFile (PickSingleFileAsync), save to own list and save to FutureAccessList

StorageApplicationPermissions.FutureAccessList.AddOrReplace(ID, StorageFile)

3. In next time use FutureAccessList

StorageApplicationPermissions.FutureAccessList.GetFileAsync(ID)
