How to change camera recorder settings in iOS ?

I want to record a video in slow motion at 120fps on an iPad Air 2. I am facing difficulties trying to configure my qMediaRecorder. I created a Camera which works fine. I created a recorder and, by default, it gives me a 1080p video at ~30fps. But when I want to change these settings, It does nothing.
Here is the settings part :
QVideoEncoderSettings settings = QVideoEncoderSettings(); settings.setCodec("video/h264"); settings.setQuality(QMultimedia::LowQuality); settings.setFrameRate(120.0); settings.setResolution(640, 480); recorder->setVideoSettings(settings);
I realize these settings were not applied, so I dig in the QtMultimedia sources for iOS and I find that the settings are hardcoded by default for the moment.
What could be the best possible solution for changing recorder settings on iOS ?
I thought about mixing Objective-C with C++ but it seems very complicated. Maybe sub-classing avfmediaassetwriter.mm for changing only the settings, if possible.
Have you another idea please?

Hi and welcome to devnet,
The nicest thing to do would be as stated in the TODO: get the information from the video encore settings control and rebuilt the plugin.
