Mimic Dropbox App video streaming - HTTP live streaming directly trough Mp4

Question

I have mp4 files on my dropbox account and when I play them on my iphone, they are correctly adapted to use Apple's HTTP Live Streaming.

I'm trying to do the same on my own app and can't get it to work correctly. I've tried linking from dropbox and from amazon aws.

I've seen on a few places that we must link to playlists files m3u8. But my files are mp4 and it works correctly on dropbox own app.

Any help will be greatly appreciated.

Here's the code:

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(moviePlaybackDidFinish)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:self.player.moviePlayer];

    NSURL *url = [NSURL URLWithString:@"https://s3.amazonaws.com/modlr_backups/CANELEIRA+4+APOIOS+BI-ARTICULADA.mp4"];

    self.player = [[MPMoviePlayerViewController alloc] init];
    self.player.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    [self.player.moviePlayer setContentURL:url];

    [self presentMoviePlayerViewControllerAnimated:self.player];

Dropbox had a blog post that explains exactly how they do it: https://tech.dropbox.com/2014/02/video-processing-at-dropbox/
