My application is relatively simple: User selects a video from a list, he selects some presets and it is automatically exported into application's temp directory.
To preview exported files, I launch a MPMoviePlayerController about 10 seconds after the video file is exported. It is a sort of progressive download.
However, the MPMoviePlayerController sends a notification that playback is finished. How can I do to playback when another process is writing a video?
