Hello everyone!
I'm currently trying to download a song from YT
the song downloads as M4A, then using the power of the Event Script it gets converted to Mp3 using the second script on this thread
https://board.jdownloader.org/showthread.php?t=70525

And because I'm downloading the JPG together with the M4A, I try to use another script to set the cover art on the resulting Mp3
using the script at the very end of this thread
https://board.jdownloader.org/showthread.php?t=87059

Mixing both scripts, I get this.

/*
    Convert audio files to mp3 format
    Trigger : A download stopped
*/

if (link.finished) {
    var input = link.downloadPath;
    var output = input.replace(/(aac|m4a|ogg|opus)$/, "mp3");

    if (input != output) {
        try {
            var ffmpeg = callAPI("config", "get", "org.jdownloader.controlling.ffmpeg.FFmpegSetup", null, "binarypath");
            var bitrate = callSync(ffmpeg, "-i", input).match(/bitrate: (\d+) kb/)[1];

            callAsync(function(error) {
                !error && getPath(input).delete();
            }, ffmpeg, "-y", "-i", input, "-b:a", bitrate + "k", output);
        } catch (e) {};
    }
}
   
/*
    Add cover art
    Trigger : Package finished
*/ 

var links = package.downloadLinks.filter(function(link) {
    return link.host == "youtube.com" && getPath(link.downloadPath).extension == "mp3";
})


if (links.length) {
    var ffmpeg = callAPI("config", "get", "org.jdownloader.controlling.ffmpeg.FFmpegSetup", null, "binarypath");

    links.forEach(function(link) {
        var cover = getPath(link.downloadPath.replace(/_\d{9}/, "_original_").replace(/mp3$/, "jpg"));

        if (cover.exists()) {
            var input = link.downloadPath;
            var output = input + ".mp3";

            callAsync(function(exitCode) {
                if (exitCode == 0) {
                    getPath(input).delete();
                    getPath(output).renameTo(input);
                }
            }, ffmpeg, "-hide_banner", "-i", input, "-i", cover, "-map", "0:0", "-map", "1:0", "-c", "copy", output);
        }
    })
}

Now the problem is I seem to be able to download the song on M4A and then convert it to MP3, however, I can't get the jpg to be set as the art for the MP3.

Any ideas how to solve this?
thanks in advance!
