setInitialParameters not takes effect

[luissandrea]

$format->setInitialParameters not takes effect.

I had to override $format->getInitialParameters over composer with:

"autoload": {
        "exclude-from-classmap": [
                "vendor\\php-ffmpeg\\php-ffmpeg\\src\\FFMpeg\\Media\\AdvancedMedia.php"
        ],
        "psr-4": {
                ...
                "FFMpeg\\Media\\": "app/Overrides/"
        }
}
