কীভাবে স্থানীয় একটি ভিডিও সুইফ্টের সাথে প্লে করবেন?


131

আমার কাছে একটি ছোট mp4ভিডিও ফাইল রয়েছে যা আমি আমার বর্তমান Xcode6 বিটা প্রকল্পে যুক্ত করেছি।

আমি আমার অ্যাপটিতে ভিডিওটি খেলতে চাই।

ঘন্টা অনুসন্ধানের পরেও আমি দূর থেকে সহায়ক কিছু খুঁজে পাচ্ছি না। সুইফট দিয়ে এটি সম্পাদন করার কোনও উপায় আছে বা আপনাকে উদ্দেশ্য-সি ব্যবহার করতে হবে? আমি কি সঠিক দিকে ইঙ্গিত পেতে পারি? আমি এই একা ভাবতে পারি না।

যেহেতু আপনি কোকোতে এটি করতে পারেন আপনি
সুইফটে

নিশ্চিত আপনি সুইফট ব্যবহার করতে পারেন!

1. ভিডিও ফাইল যুক্ত করা হচ্ছে

video.m4vআপনার এক্সকোড প্রকল্পে ভিডিও যুক্ত করুন (এটি কল করুন ) Add

২. আপনার ভিডিও চেক করা বান্ডিলের মধ্যে রয়েছে

খুলুন Project Navigator cmd+1

তারপর নির্বাচন your project root> your Target> Build Phases> Copy Bundle Resources

আপনার ভিডিও এখানে থাকা আবশ্যক । যদি এটি না হয়, তবে আপনার এটি প্লাস বোতামটি ব্যবহার করে যুক্ত করা উচিত

এখানে চিত্র বর্ণনা লিখুন

3. কোড

আপনার ভিউ কন্ট্রোলারটি খুলুন এবং এই কোডটি লিখুন।

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        playVideo()
    }

    private func playVideo() {
        guard let path = Bundle.main.path(forResource: "video", ofType:"m4v") else {
            debugPrint("video.m4v not found")
            return
        }
        let player = AVPlayer(url: URL(fileURLWithPath: path))
        let playerController = AVPlayerViewController()
        playerController.player = player
        present(playerController, animated: true) {
            player.play()
        }
    }
}

এই সমস্যার সমাধানের বেশিরভাগ অংশ হ'ল ক্ষেত্রটি "টার্গেটগুলিতে যুক্ত করুন" -> প্রকল্পের নামটি পরীক্ষা করা যখন আমরা সেই প্রকল্পটি আমাদের প্রকল্পে অনুলিপি করি। ধন্যবাদ এই সমাধানটি আমার পক্ষে কাজ করেছে ..

@ মোবিবব অবশ্যই AVPlayerViewController বিদ্যমান :-) আপনি কি import AVKit?

অন্য সুইফট 3 উদাহরণ। প্রদত্ত সমাধানটি আমার পক্ষে কার্যকর হয়নি।

private func playVideo(from file:String) {
    let file = file.components(separatedBy: ".")

    guard let path = Bundle.main.path(forResource: file[0], ofType:file[1]) else {
        debugPrint( "\(file.joined(separator: ".")) not found")
        return
    }
    let player = AVPlayer(url: URL(fileURLWithPath: path))

    let playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame = self.view.bounds
    self.view.layer.addSublayer(playerLayer)
    player.play()
}

useage:

playVideo(from: "video.extension")

দ্রষ্টব্য: ভিডিওটি প্রকল্পের জন্য উপলব্ধ কিনা তা নিশ্চিত করার জন্য বিল্ড পর্যায়ের অধীনে অনুলিপি বান্ডিল সংস্থানগুলি পরীক্ষা করুন ।


এই সমাধানটি অন্যান্য স্তরগুলির সাথে একসাথে কাজ করে, এটি সংখ্যাগরিষ্ঠর পক্ষে ভোট দেওয়া তার চেয়ে ভাল সমাধান, ধন্যবাদ!

  1. UIViewভিডিও প্লে করার জন্য সাবক্লাস তৈরি করুন (মূলত আপনি যে কোনও UIViewঅবজেক্ট ব্যবহার করতে পারেন এবং কেবলমাত্র প্রয়োজন হয় AVPlayerLayerI আমি এইভাবে সেটআপ করি কারণ এটি আমার পক্ষে আরও পরিষ্কার)
