Cannot make a Rainbow video call from iOS app

Hello,

I'm working to make a kiosk type Rainbow app on iOS that makes a voice or video call to one of the Rainbow contacts.

I followed Managing Voice and Video section of Rainbow API HUB and was able to make a voice call from my real iPhone to a Rainbow agent on a Windows.

However, I cannot make a video call.

Here is a scenario what I am trying with my iOS app:

1. Sign-in to Rainbow

2. Download the contacts

3. Make a video call to one of the contacts.

I set RTCCallFeatureFlags correctly and the Windows rainbow showed an option for the video when I made a call from the app.

 

In RTCService, there is requestMicrophoneAccess method but I could not find similar method that requests a user to access the camera.

I read this section at least twice but could not find a solution.

Am I missing something to create a video call from the app on iOS?

Thanks

  Thanks in advance,

  Hello Olivier, thank you for your support.

  Here is a code that originating the video call, 

  mCurrentCall = mServicesManager.rtcService.beginNewOutgoingCall(with: contact, withFeatures: features) as RTCCall?

  features is set as

  RTCCallFeatureFlags.init(rawValue: RTCCallFeatureFlags.audio.rawValue | RTCCallFeatureFlags.localVideo.rawValue)!

   

  It actually makes a call and the other party, Windows Rainbow client rings and shows options for Voice and Video conversation.

  When I click the video icon on the Windows Rainbow client then it makes a 2-way audio conversation but no video stream is sent from the iPhone.

  The app receives NSNotification.Name.telephonyServiceDidUpdateCall with CallStatus.connecting and then CallStatus.established once the other party clicks the video icon.

   

  Thanks,

  Hiroki

  Hello Oliver, Can I attach text files to this thread?

  I took the log but I do not see any option for it.

  Thanks,

  Hello Olivier,

  I added the following line to confirm if the camera usage is granted before placing a video call.

  AVCaptureDevice.authorizationStatus(for: AVMediaType.video)

  I confirmed that the status was .authorized when I placed a video call but the call still did not send video stream.

  Just in case I tried a Facetime video call to verify the issue is not on my iPhone (iphone6) hardware and the Facetime video call worked as expected. So I do not think this is not a hardware related problem.

  Thanks,

  Hiro

  Hi Olivier, 

  In the log file I found rtcServiceDidAddCapturesSession event that will be fired when the video capture can be started.

  Also I see the following logs that indicate that a video and audio track were created.

  "RTCIceServer 0x2834b4f00 <urls (\n \"turns:turn-dal1.openrainbow.com:443?transport=tcp\"\n), tlsCertPolicy 0, hostName "
  )
  
  

  Just in case I downloaded the rainbow app on my iphone an made video calls that successfully completed.

  Olivier, 

  This issue has been solved that I found incorrect code in my functions to set the video device.

  After correcting these errors then my app is able to send the video stream.

  Thank you for your help!

  Hiro
