    Swift

    case backgroundVideoSourceAlreadyExists = 10407
  • The background video source is currently live. If your app responds to UIApplicationWillEnterForegroundNotification, it is possible your app will receive that notification before the broadcast SDK does. Dispatching a block to the main queue will allow the SDK to receive that notification, then the removeImageSourceOnAppBackgrounded will be safe to call.

    Declaration

    Objective-C

    IVSBroadcastErrorBackgroundVideoSourceIsLive = 10408

    Swift

    case backgroundVideoSourceIsLive = 10408
  • The background video source is currently live because the attached camera is waiting to receive the AVCaptureSessionInterruptionEndedNotification notification to be fired. This is fired some time after the app returns to the foreground. Waiting for that notification and dispatching a block to the main queue that calls this API again will resolve this error if the source of the error is the attached camera. An alternative workaround would be to detach and reattach the camera.

    Declaration

    Objective-C

    IVSBroadcastErrorBackgroundVideoSourceIsWaitingForCamera = 10409

  • This is thrown when PCM data is submitted via onPCMBuffer with multiple AudioBuffer structs attached and one of the following is false All AudioBuffers have the same data length. The channels are non-interleaved (planar). The number of channels reported by the format is the same as the number of AudioBuffer structs. All of the AudioBuffers are single channel (together they can create multiple channels, but each individually must be single channel). There are only 2 AudioBuffer structs (if there are more than 2, all channels after 2 will be droppped). When this error is emitted, only a single audio channel will be processed, unless the error is too many channels, at which point 2 channels will be processed. This error will only be emitted once per audio source.

    Declaration

    Objective-C

    IVSBroadcastErrorPCMUnsupportedSample = 10411

    Swift

    case pcmUnsupportedSample = 10411

    IVSBroadcastErrorInPhoneCall = 10414

    Swift

    case inPhoneCall = 10414
