set rateControl with setVideoEncoderConfiguration

[romv99]

I am currently working on modifying the encoder settings of a Bosch Dinion 3000IR camera. While I have successfully edited the quality and resolution properties, I am encountering difficulties with the rateControl property. Despite multiple attempts with values form videoEncoderConfigurationOptions, changes to rateControl do not seem to take effect.

Here an example of the object I use with setVideoEncoderConfiguration:

const configParams = {
    "$": {
        "token": "EncCfg_L1S2",
        "GovLength": 255,
        "Profile": "Main"
    },
    "name": "Balanced",
    "useCount": 1,
    "encoding": "H264",
    "resolution": {
        "width": 768,
        "height": 432
    },
    "rateControl": {
        "frameRateLimit": 30,
        "encodingInterval": 1,
        "bitrateLimit": 3400
    },
    "multicast": {
        "address": {
            "type": "IPv4",
            "IPv4Address": "0.0.0.0"
        },
        "port": 60010,
        "TTL": 64,
        "autoStart": false
    },
    "quality": 50
}

my implementation of the function:

const camera = new Cam({
                hostname: device.network.ip,
                username: process.env.ONVIF_USER,
                password: process.env.ONVIF_PWD,
                port: 80,
            }, function (err) {
                if (err) {
                    return reject(err);
                }
                camera.setVideoEncoderConfiguration(configParams, (err) => {
                    if (err) {
                        console.log(err)
                        return reject(err);
                    }
                    resolve();
                })
            });
