[suzhongzhou1991]

here is the demo code:

VideoGenerator.current.fileName = "test"
VideoGenerator.current.shouldOptimiseImageForVideo = true
VideoGenerator.current.maxVideoLengthInSeconds = 15

    var localImages = [] as! [UIImage]
    for imageName in images {
        let imagePath = URL.init(fileURLWithPath: basePathString!).appendingPathComponent("lowpoly").appendingPathComponent(imageName)
        localImages.append(UIImage.init(contentsOfFile: imagePath.path)!)
    }
    
    let audioURL = Bundle.main.url(forResource: "audio", withExtension: "mp3")
    VideoGenerator.current.generate(withImages: localImages, andAudios: [audioURL!], andType: .singleAudioMultipleImage, { (progress) in
        print(progress)
    }, success: { (url) in
        print(url)
    }, failure: { (error) in
        print(error)
    })
