進(jìn)程之間通訊代碼使用方法.

第一步.

解壓,添加到項目.必須也勾選擴(kuò)展

第二步 SampleHandler 這個文件中,添加如下代碼

#import <AgoraRtcKit/AgoraRtcEngineKit.h>
#import "RongRTCBufferUtil.h"

@interface SampleHandler ()
@property(nonatomic , strong) RongRTCClientSocket *clientSocket;
@property (nonatomic, assign) size_t w;
@property (nonatomic, assign) size_t h;
@property (nonatomic,assign) AgoraVideoRotation rotate;
@property (nonatomic,assign)NSTimeInterval lastSendTs;
@property (nonatomic,)CMSampleBufferRef  bufferCopy;
@property (nonatomic,weak) NSTimer *bufferTimer;
@end

懶加載

- (RongRTCClientSocket *)clientSocket {
    if (!_clientSocket) {
        _clientSocket = [[RongRTCClientSocket alloc] init];
        [_clientSocket createCliectSocket:(int)_w height:(int)_h];
    }
    return _clientSocket;
}

在此方法里

- (void)processSampleBuffer:(CMSampleBufferRef)sampleBuffer withType:(RPSampleBufferType)sampleBufferType {
 //判斷是視頻的話.調(diào)用下面的方法.進(jìn)行編碼通訊.
}
- (void)sendData:(CMSampleBufferRef)sampleBuffer{
    if (_w == 0 || _h == 0) {
        CVPixelBufferRef buffer = CMSampleBufferGetImageBuffer(sampleBuffer);
        _w = CVPixelBufferGetWidth(buffer);
        _h = CVPixelBufferGetHeight(buffer);
    }
    [self.clientSocket encodeBuffer:sampleBuffer];

}

第三步在主APP的控制器內(nèi)調(diào)用

@property (nonatomic, strong) RongRTCServerSocket *screenServerSocket;

懶加載

-(RongRTCServerSocket *)screenServerSocket{
    if (!_screenServerSocket) {
        RongRTCServerSocket *socket = [[RongRTCServerSocket alloc] init];
        socket.delegate = self;
        _screenServerSocket = socket;
    }
    return _screenServerSocket;
}

下面是代理方式.就能收到擴(kuò)展過來的buffer了,是解碼過的.

-(void)VZdidProcessSampleBuffer:(CVPixelBufferRef)cvPixelBufferRef andWith:(CMTime)time{
    if (self.isScreen) {
        DebugLog(@"%@",cvPixelBufferRef);
        [self.screenVideos.consumer consumePixelBuffer:cvPixelBufferRef withTimestamp:time rotation:self.currerRotation];
    }
}
-(void)startPushOrStopPush:(BOOL)isStart{
    self.isScreen = isStart;
}

接到擴(kuò)展啟動的時候APP調(diào)用的方法.

- (void)screenStartAction {
    ///第一種方法實現(xiàn)的地方
    
    if (!_screenServerSocket) {
        CGFloat W = (MIN(ScreenWidth, ScreenHeight)) * UIScreen.mainScreen.scale;
        CGFloat H = MAX(ScreenWidth, SCREEN_HEIGHT) * UIScreen.mainScreen.scale;
        [self.screenServerSocket createServerSocket:W height:H];
    }
    dispatch_async(dispatch_get_main_queue(), ^{
        [self.rtcEngine muteAllRemoteAudioStreams:YES];
        [self.rtcEngine muteAllRemoteVideoStreams:YES];
        [self.rtcEngine setVideoSource:self.screenVideos];
    });

RongRTCServerSocketProtocol 這就是代理..

再貼上ScreenVideoSouces

#import <Foundation/Foundation.h>
#import <AgoraRtcKit/AgoraRtcEngineKit.h>

@protocol VZScreenShareVideoDelegate <NSObject>
-(void)startPushOrStopPush:(BOOL)isStart;
@end

NS_ASSUME_NONNULL_BEGIN

@interface VZScreenShareVideo : NSObject <AgoraVideoSourceProtocol>
@property (nonatomic,weak) id<VZScreenShareVideoDelegate> delegate;        

@end

NS_ASSUME_NONNULL_END

#import "VZScreenShareVideo.h"
@implementation VZScreenShareVideo
@synthesize consumer;

-(BOOL)shouldInitialize{
    return YES;
}
- (AgoraVideoBufferType)bufferType{
    return AgoraVideoBufferTypePixelBuffer;
};
-(AgoraVideoContentHint)contentHint{
    return AgoraVideoContentHintNone;
}
- (AgoraVideoCaptureType)captureType{
    return AgoraVideoCaptureTypeScreen;
}
- (void)shouldDispose {

}
- (void)shouldStart {
    if (self.delegate) {
        [self.delegate startPushOrStopPush:YES];
    }
}
- (void)shouldStop {
    if (self.delegate) {
        [self.delegate startPushOrStopPush:NO];
    }
}
