ZFScreenRecorder 0.0.5

Maintained by zhfeng.

You want to add pod 'ZFScreenRecorder', '~> 0.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'ZFScreenRecorder', '~> 0.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try ZFScreenRecorder

基于GPUImage实现的录屏，性能很好。

安装

target 'TargetName' do
pod 'ZFScreenRecorder'
end

核心思路

ZFScreenVideoCamera是用来采集视频和音频的信息，音频信息直接发送给GPUImageMovieWriter；视频信息传入响应链作为源头，渲染后的视频信息再写入GPUImageMovieWriter，文件保存在沙盒里。 ZFScreenVideoCamera实现灵感来源于GPUImageVideoCamera。 ZFScreenVideoCamera和GPUImageVideoCamera相似，唯一不同的是视频的采集方式。ZFScreenVideoCamera采用截屏方式，GPUImageVideoCamera采用的是摄像头。所以ZFScreenVideoCamera完美兼容GPUImage的所有功能，在视频的处理上节约了大量开发时间。

流程图

使用

    _movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:movieURL size:finalSize];
    //截屏
    self.videoCamera = [[ZFScreenVideoCamera alloc] initWithView:screenView inRect:rect];
    self.videoCamera.runBenchmark = YES;
    [self.videoCamera addTarget:_movieWriter];
    //*/
    self.videoCamera.microphoneEnabled = microphoneEnabled;
    if (microphoneEnabled) {
        self.videoCamera.audioEncodingTarget = _movieWriter;
    }
    _movieWriter.encodingLiveVideo = YES;
    //开始录屏
    [self.videoCamera startScreenCapture];
    //视频写文件
    [_movieWriter startRecording];
