Even more extended version
V2: If the "Best Quality Image" has been downloaded too (and it finished before the audio file, *and* it has the default filename) have ffmpeg use that image as the "cover" for the mp3 so it will be shown in media players when playing this mp3.
(There's surely a better way to get the filename for the best quality image - or other image to be used for the cover. This works for now. Anyone wants to improve it, feel free to do so - and post the update in here!)
Code:
function run() {
// Converts aac/m4a/ogg/opus files to mp3.
// Trigger: "A Download Stopped"
// Requires ffmpeg/ffprobe. Uses ffmpeg/ffprobe settings if available.
// Does NOT overwrite the destination file (mp3) if it already exists.
// V2: If the "Best Quality Image" is downloaded (and finished before the audio file!)
// then have ffmpeg add the image as cover into the mp3 file
// (Assumes default filename for images in the youtube plugin - if not, customize accordingly)
var testExceptionHandling = false; // Boolean to trigger a test exception
var writeErrorToLogfile = true; // Boolean to determine if errors should be written to a log file
var deleteSourceFile = true; // Set whether the source file should be deleted after conversion.
try {
if (!link.isFinished()) {
throw new Error("Download is not finished yet"); // Throw error if the download is not completed.
