<p>In the past I've successfully used <a href="https://github.com/kewlbear/FFmpeg-iOS-build-script" rel="noreferrer">this build script</a> to integrate ffmpeg.</p>
<p>The pictorial instructions that follow work for both Objective-C and Swift projects, unless otherwise noted.</p>
<p>As a side note, you should make sure ffmpeg is the correct tool for the job. AVFoundation and VideoToolBox are both very powerful tools that Apple provides for doing many video operations.</p>
<p>For late 2018, get the folder from the kewlbear repo which will appear as in the below image, however, there is an additional file build-ffmpeg-iOS-framework.sh. In terminal, cd to that folder.  With the current version, you must run <code>build-ffmpeg-iOS-framework.sh</code> , not <code>build-ffmpeg.sh</code> to follow the following tutorial:</p>
<h1>Once you've executed the script, you'll have the following files:</h1>
<p><a href="https://i.stack.imgur.com/7au7a.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7au7a.png" alt="enter image description here" /></a></p>
<h1>Copy the FFmpeg-iOS folder to your project:</h1>
<p><a href="https://i.stack.imgur.com/Y4xcJ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Y4xcJ.png" alt="enter image description here" /></a></p>
<h1>Add the files to your project:</h1>
<p>(by dragging and dropping from finder)
<a href="https://i.stack.imgur.com/qcYzG.png" rel="noreferrer"><img src="https://i.stack.imgur.com/qcYzG.png" alt="enter image description here" /></a></p>
<h1>With these settings:</h1>
<p><a href="https://i.stack.imgur.com/6jx4L.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6jx4L.png" alt="enter image description here" /></a></p>
<h1>Add the include directory to your headers:</h1>
<p><a href="https://i.stack.imgur.com/vluPv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/vluPv.png" alt="enter image description here" /></a></p>
<h1>Link the required libraries:</h1>
<p><a href="https://i.stack.imgur.com/dm5en.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dm5en.png" alt="enter image description here" /></a></p>
<h1>Add the headers to the bridging header (Swift-only):</h1>
<pre><code>#import &quot;libavcodec/avcodec.h&quot;
#import &quot;libavdevice/avdevice.h&quot;
#import &quot;libavfilter/avfilter.h&quot;
#import &quot;libavformat/avformat.h&quot;
#import &quot;libavutil/avutil.h&quot;
#import &quot;libswresample/swresample.h&quot;
#import &quot;libswscale/swscale.h&quot;
</code></pre>
<p>Objective-C simple example:</p>
<pre><code>#import &quot;AppDelegate.h&quot;
#import &quot;libavformat/avformat.h&quot;

@interface AppDelegate ()
@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    AVFormatContext *context = avformat_alloc_context();

    return YES;
}

@end
</code></pre>
<p>And in Swift:</p>
<pre><code>import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -&gt; Bool {

        let context = avformat_alloc_context()

        return true
    }
}
</code></pre>


<p>I have compiled the ffmpeg library and it was successfully created many files inside my folder.</p>

<p>Now I need to implement the same in my Xcode project. What is the best way for adding to my project.</p>

<p>I wish to create one framework but what files I need to add?</p>

<p>I have many .c files and .a files available after compilation.</p>

我已经编译了ffmpeg库，它成功地在我的文件夹中创建了许多文件。现在，我需要在我的Xcode项目中实现相同的功能。添加到我的项目的最佳方式是什么？我希望创建一个框架，但是我需要添加什么文件？编译后，我有许多.c文件和.a文件可用。
