Hey @bhanu,

Thanks for using the dev forum!

To show this button, you have to implement the onClickShareScreen callback in MobileRTCMeetingServiceDelegate.

Thanks!

Hello @Michael_Condon

Thanks for your reply!

Can you please share that function with me?

And in this class I need to implement that function?

class SampleHandler: RPBroadcastSampleHandler, MobileRTCScreenShareServiceDelegate {

    var screenShareService: MobileRTCScreenShareService?

    override init() {
        super.init()
        screenShareService?.appGroup = "group.com.hf.ZoomMeeting"
        screenShareService = MobileRTCScreenShareService()
        screenShareService?.delegate = self
    }
    
    override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {
        // User has requested to start the broadcast. Setup info from the UI extension can be supplied but optional.
        screenShareService?.broadcastStarted(withSetupInfo: setupInfo)
    }
    
    override func broadcastPaused() {
        // User has requested to pause the broadcast. Samples will stop being delivered.
        screenShareService?.broadcastPaused()
    }
    
    override func broadcastResumed() {
        // User has requested to resume the broadcast. Samples delivery will resume.
        screenShareService?.broadcastResumed()
    }
    
    override func broadcastFinished() {
        // User has requested to finish the broadcast.
        screenShareService?.broadcastFinished()
    }
    
    override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType) {
        self.screenShareService?.processSampleBuffer(sampleBuffer, with: sampleBufferType)
        
        switch sampleBufferType {
        case RPSampleBufferType.video:
            // Handle video sample buffer
            break
        case RPSampleBufferType.audioApp:
            // Handle audio sample buffer for app audio
            break
        case RPSampleBufferType.audioMic:
            // Handle audio sample buffer for mic audio
            break
        @unknown default:
            // Handle other sample buffer types
            fatalError("Unknown type of sample buffer")
        }
    }
    func mobileRTCScreenShareServiceFinishBroadcastWithError(_ error: Error!) {
            finishBroadcastWithError(error)
        print(error)
    }
    
}

Thanks!

Hey @bhanu

This would actually be located in your main target. Something like this:

extension yourDelegate: MobileRTCMeetingServiceDelegate {
    func onClickShareScreen(_ parentVC: UIViewController) {
        // if you want to trigger the broadcast here, you would present a ReplayKitPickerView here
    }
}

Thanks!
Michael

Hi @bhanu,

Is this error accompanied by any incorrect behavior? If so, please provide additional context around when you’re seeing so that we can better assist.

Also, which version of the SDK are you current using?

Thanks!

Hi @jon.zoom,

I’m using Zoom meeting v5.7.6.1080 SDK.

I don’t know why this error is coming and also getting crash in override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType)

[jon.zoom (Jon)]

Hi @bhanu,

Apologies, but can you describe what actions you are taking leading up to this crash? It is unclear when this is happening, so if you can describe the steps to reproduce this it would be helpful.

Thanks!
