is there a way to force loading a StorageFile in memory?

I have a StorageFile that I want to use as input for a Media Composition (as a Media Clip).

I'm hoping loading everything in memory, to speed things up. I don't know how to do this - is there any way to do it?

    Welcome to our Microsoft Q&A platform!

    The MediaClip.CreateFromFileAsync method accepts a parameter type of IStorageFile, which means you need to pass in a variable of type StorageFile.

    Although we can use a MemoryStream to save a file stream in memory, MediaClip doesn't have a method of CreateFromStreamAsync, so in your case you can only load data from the file.


    If you are establishing a connection between MediaClip and Stream, you can use StorageFile.ReplaceWithStreamedFileAsync as a relay.

    You can first read the StorageFile as a Stream, then use this method to convert the Stream to a StorageFile when needed, and pass it to MediaClip.

    However, it should be noted that loading the file into memory has no effect on the speed of MediaComposition.

    Of couse, you can read StorageFile as a stream (stream is in memory)
