We have this iOS project that uses QuickBlox Video Chat. Basing from the sample app they've given, we were able to implement it successfully. When we tested it, the quality looks a bit bad. Does anyone know how to up the quality of the video chat?
Thanks.
you can change the video quality by setting kQBVideoChatFrameQualityPreset in videoChatConfiguration,
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];
The available options:
//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);
