I have a document based app here where I need to generate thumbnails from videos I have available in NSFileWrappers. Problem is that I can’t get the file URL from the filewrapper, and I can’t seem to create a AVURLAsset without a URL.
Anybody have any suggestions as to an alternative way of doing this? Either a different way than AVAssetImageGenerator to create a video thumbnail, or some way to create an AVAsset from the data in the filewrapper?
So it turns out there’s no way to do this, other than saving the file somewhere new and then generating the thumbnail from that.
So what I did instead is that when I add the videos to my package I create the thumbnail then based on the location that I added the file from (I copy the files into my own custom packages).
