ios - Quickblocks 接收视频通话崩溃

Question

我正在尝试在 swift 中集成快速 block 。一切正常，但是当我收到其他用户的调用请求时，我的应用程序崩溃了。我收到此错误

[CAMetalLayerDrawable texture] should not be called after already presenting this drawable. Get a nextDrawable instead.

我的 QBRTCClientDelegate 如下所示

func session(_ session: QBRTCBaseSession, receivedRemoteVideoTrack videoTrack: QBRTCVideoTrack, fromUser userID: NSNumber) {

    if (session as! QBRTCSession).id == self.session?.id {

         self.remoteView = QBRTCRemoteVideoView.init()
         self.remoteView?.videoGravity = AVLayerVideoGravity.resizeAspect.rawValue
         self.remoteView?.clipsToBounds = true
         self.remoteView?.setVideoTrack(videoTrack)
         self.remoteView?.tag = userID.intValue
         self.stackView.addArrangedSubview((self.remoteView)!)


    }
}

Answer 1

请记住，Metal 仅适用于 A7 或更高处理器。我可以建议您强制使用 OpenGLES 绘图而不是 Metal，现在，只需执行以下操作:

QBRTCRemoteVideoView.preferMetal = NO
