Description

list<object> supportedViewfinderFrameRateRanges(size resolution = undefined)
...
If the optional parameter resolution is specified, the returned list is reduced to frame rate ranges supported for the given resolution.
...

However, it seems that the function always returns ALL frame-rate ranges, regardless of specified resolution. This might be a back-end related thing, also, but I see the same behavior with 5 different cameras/drivers/manufacturers. Example:

        Camera {
            id: camera

            Component.onCompleted: {
                    var resolutions = camera.supportedViewfinderResolutions();
                    for (var j=0; j< resolutions.length; j++) {
                        console.log(resolutions[j]);
                        console.log(JSON.stringify(resolutions[j]));
                        console.log(JSON.stringify(camera.supportedViewfinderFrameRateRanges(resolutions[j])));
                    }
                }
            }
