Mobile-ffmpeg: [Swift] callback delegate not called

Created on 20 Nov 2019 · 2Comments · Source: tanersener/mobile-ffmpeg

I am using ffmpeg to convert image to video and I dont get any statistick callback.

In viewDidLoad() I am seting delegate:

override func viewDidLoad() {
        super.viewDidLoad()

        setup()
        MobileFFmpegConfig.setStatisticsDelegate(self)
    }

Here is the execution:

func generate(withImageURL url: URL, duration: Double, fileName: String) {
        if let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first {
            let documentDirectory = URL(fileURLWithPath: path)
            let newPath = documentDirectory.appendingPathComponent("\(fileName).mov")
            MobileFFmpeg.execute("-loop 1 -i \(url.absoluteString) -pix_fmt yuv420p -t \(duration) \(newPath.absoluteString)")

        }
    }

And here is the delegate:

extension ImageCuttingVC: StatisticsDelegate {
    func statisticsCallback(_ statistics: Statistics!) {
        DispatchQueue.main.async {
            print(statistics.getTime())
        }
    }
}
