Convert GIF to MP4 on device

问题

Is it possible to take a remote (but I can download it first if needed) GIF sequence and make a MPMoviePlayerViewController playable mp4 on the device?

I have tried using http://api.online-convert.com/, but the API doesn't suit and the free version is too restricted for our needs.

Imagemagick for iOS also doesn't seem to include GIF support.

Swift 3.0 version.

Usage

let data = try! Data(contentsOf: Bundle.main.url(forResource: "gif", withExtension: "gif")!)
let tempUrl = URL(fileURLWithPath:NSTemporaryDirectory()).appendingPathComponent("temp.mp4")
GIF2MP4(data: data)?.convertAndExport(to: tempUrl, completion: { })
