I use Replaykit and webrtc to share my iOS screen to a Chrome web browser.but video is stuck

[王收拾收拾]

Replaykit capture screen api:- (void)startCaptureWithHandler:(nullable void(^)(CMSampleBufferRef sampleBuffer, RPSampleBufferType bufferType, NSError * _Nullable error))captureHandler completionHandler:(nullable void(^)(NSError * _Nullable error))completionHandler

transfer CMSampleBufferRef to webrtc to send to Chrome web browser:

- (void)didCaptureVideoBuffer:(CMSampleBufferRef)sampleBuffer {

    if (CMSampleBufferGetNumSamples(sampleBuffer) != 1 || !CMSampleBufferIsValid(sampleBuffer) ||

        !CMSampleBufferDataIsReady(sampleBuffer)) {

        return;

    }

    

    CVPixelBufferRef pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);

    if (pixelBuffer == nil) {

        return;

    }

    size_t  width = CVPixelBufferGetWidth(pixelBuffer);

    RTCCVPixelBuffer *rtcPixelBuffer = [[RTCCVPixelBuffer alloc] initWithPixelBuffer:pixelBuffer];

    int64_t timeStampNs =

    CMTimeGetSeconds(CMSampleBufferGetPresentationTimeStamp(sampleBuffer)) * NSEC_PER_SEC;

    RTCVideoFrame *videoFrame = [[RTCVideoFrame alloc] initWithBuffer:rtcPixelBuffer

                                                             rotation:RTCVideoRotation_0

                                                          timeStampNs:timeStampNs];

    [self.delegate capturer:self didCaptureVideoFrame:videoFrame];

}

server is created with nodejs,current problem is that the browser's video is always stuck and stop playing, i checked the iOS end and found it send no data any longer, but the audio is still normal, anyone can help me ,thanks
