Question: How to force download filetype to mp4

[inglesuniversal]

I tried with two videos and got them in 3gp

How can I force to always get the mp4 version of it.

and

Is it possible to get the file in mp3?

just loop through all available formats until you find the one that's mp4:

$downloadOptions = $youtube->getDownloadLinks("https://www.youtube.com/watch?v=aqz-KE-bpKQ");

foreach ($downloadOptions->getCombinedFormats() as $format) {

    if (strpos($format->mimeType, 'video/mp4') !== false) {
        echo $format->url;
        break;
    }
}

Is it possible to get the file in mp3?

I don't believe YouTube ever returns links to mp3 files... you would have to download audio-only version of whatever format they provide, and then convert it yourself using ffmpeg or something.
