@rahveekotadiya ,

I'm sorry that you are experiencing this issue. Would you be able to provide a sample of code that you are using to start the camera capture? Has it ever worked for you or does this always happen? It is only failing on the iPhone Xr or does it happen on other devices as well?

Thank you,

Ryan

Hello @paynerc

Recently i updated framework with cocoapods with latest twillio sdk. I used manual framwork before this.

i find the change between old code and new code

like this is old Method for connect room:

self.room = [TwilioVideo connectWithOptions:connectOptions delegate:self];

and below is new method:

self.room = [TwilioVideoSDK connectWithOptions:connectOptions delegate:self];

Is there any kind of issue with this because of now i got participant audio but not able to see his video my participant able to see and listen audio both but my side it's not working. now its not working in any devices.

Below code is for start camera capture

• (void)startPreview {

  AVCaptureDevice frontCamera = [TVICameraSource captureDeviceForPosition:AVCaptureDevicePositionFront]; AVCaptureDevice backCamera = [TVICameraSource captureDeviceForPosition:AVCaptureDevicePositionBack];

  if (frontCamera != nil || backCamera != nil) { self.camera = [[TVICameraSource alloc] initWithDelegate:self]; self.localVideoTrack = [TVILocalVideoTrack trackWithSource:self.camera enabled:YES name:@"Camera"]; // Add renderer to video track for local preview [self.localVideoTrack addRenderer:self.previewView]; //Toast(@"Video track created");

  if (frontCamera != nil && backCamera != nil) {
      UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(flipCamera)];
      [self.previewView addGestureRecognizer:tap];
  }
  
  [self.camera startCaptureWithDevice:frontCamera != nil ? frontCamera : backCamera
                           completion:^(AVCaptureDevice *device, TVIVideoFormat *format, NSError *error) {
                               if (error != nil) {
                                   NSString *errorStr = [NSString stringWithFormat:@"Start capture failed with error.\ncode = %lu error = %@", error.code, error.localizedDescription];
                                   Toast(errorStr);
                               }
                               else
                               {
                                   self.previewView.mirror = (device.position == AVCaptureDevicePositionFront);
                               }
                           }];

  } else { Toast(@"No front or back capture device found!") } }

@rahveekotadiya,

In your application are you listening for the didSubscribeToVideoTrack:... RemoteParticipantDelegate call back method and then add the published track to a renderer, such as TVIVideoView?

As far as not being able to capture, by chance are you attempting to start the camera capture when your application is in the background, via accepting a CallKit notification or the like? I saw an error message in your log file that seemed concerning:

2020-04-29 18:02:44.870688+0530 DOCTERZ[5219:1036955] [BackgroundTask] Background Task 9 ("Called by TwilioVideo, from -[TVICameraCapturePipeline videoPipelineWillStartRunning]"), was created over 30 seconds ago. In applications running in the background, this creates a risk of termination. Remember to call UIApplication.endBackgroundTask(_:) for your task in a timely manner to avoid this.

With regards to the BackgroundTask message: This is a new message being output by iOS 13.4.1, which at this time is benign. It is present any time the camera capture starts, not just when a room is joined in the background via CallKit notification. We are investigating our usage of Background Tasks in iOS 13 and will be addressing that message in a future release.

With that said, is there any further info on the questions I asked the other day, @rahveekotadiya?
