Question

Is there anyway to download a specific codec of video or audio?

Other details

I want to download 1080p mp4 video in h.264(avc) codec and mp4 audio in mp4a codec. But I don't know how to do it.

The FormatOptions cannot choose codec apparently.

export interface FormatOptions {
    /**
     * Video quality; 360p, 720p, 1080p, etc... also accepts 'best' and 'bestefficiency'.
     */
    quality?: string;
    /**
     * Download type, can be: video, audio or video+audio
     */
    type?: 'video' | 'audio' | 'video+audio';
    /**
     * Language code, defaults to 'original'.
     */
    language?: string;
    /**
     * File format, use 'any' to download any format
     */
    format?: string;
    /**
     * InnerTube client.
     */
    client?: InnerTubeClient;
}
