OGGs not obtainable in HTML5 even when converted to MP3 #1215

I wrote a custom converter to convert ogg files to mp3, since oggs are not natively supported on HTML5. However, whenever I build the project for HTML5, the resources are not obtainable even though they should have been converted to mp3 files. This is fixed by including the stb_ogg_sound library, in which case the sound files will be obtainable and be converted to mp3 files, but it's a little inconvenient that I have to include that library even though in the end there should be no ogg file processing.

This is the code for my converter:

package convert;

class ConvertOgg2Mp3 extends hxd.fs.Convert {
    function new() {
        super("ogg", "mp3");
    }

    override function convert() {
        var cmd = "ffmpeg";
        var args = ["-hide_banner", "-loglevel", "error", "-i", srcPath, "-ar", "44100", dstPath];
        command(cmd, args);
    }

    // register the convert so that it can be found
    static var _ = hxd.fs.Convert.register(new ConvertOgg2Mp3());

    // used for macro compilation
    public static function doNothing() {}
}

And this is my build.hxml
