QuickBlox视频聊天质量

Question

我们有这个使用QuickBlox视频聊天的iOS项目。从他们提供的示例应用程序开始，我们能够成功实现它。当我们测试它时，质量看起来有点不好。有谁知道如何提高视频聊天的质量？

谢谢。

您可以通过在videoChatConfiguration设置kQBVideoChatFrameQualityPreset更改视频质量，

NSMutableDictionary *videoChatConfiguration = [[QBSettings videoChatConfiguration] mutableCopy]; 
    [videoChatConfiguration setObject:@20 forKey:kQBVideoChatCallTimeout]; 
    [videoChatConfiguration setObject:@10 forKey:kQBVideoChatVideoFramesPerSecond]; 
    // config video quality here 
    [videoChatConfiguration setObject:AVCaptureSessionPresetMedium forKey:kQBVideoChatFrameQualityPreset]; 
    [QBSettings setVideoChatConfiguration:videoChatConfiguration]; 

可用的选项：

//achieve high quality video and audio output.defaultvalue. 
AVF_EXPORT NSString *const AVCaptureSessionPresetHigh NS_AVAILABLE(10_7, 4_0); 
//achieve output video and audio bitrates suitable for sharing over WiFi. 
AVF_EXPORT NSString *const AVCaptureSessionPresetMedium NS_AVAILABLE(10_7, 4_0); 
//achieve output video and audio bitrates suitable for sharing over 3G. 
AVF_EXPORT NSString *const AVCaptureSessionPresetLow NS_AVAILABLE(10_7, 4_0);
