Skifta allows streaming from your computer to the Xbox One if you have a media server on your computer like Plex or Windows Media Center. If you don't know what a media server is and don't have one it will not work.
You use Skitta like a remote control and what you select to play will show up on your Xbox One as long as you installed the video player app.
I can stream and play all my home videos and see all my pictures with no problem.
