Description of your issue, suggested solution and other information

The documentation states:

Progress hooks are guaranteed to be called at least once
    (with status "finished") if the download is successful.

Now when skip_download or simulate are True the progress_hook is never called. Even though there are files downloaded (metadata etc.)

Used options are:

self.ydl_opts = {
            'writeinfojson':True,       
            'writethumbnail':True,
            #'writesubtitles':True,
            #'writeautomaticsub':True,
            #'allsubtitles':True,
            'noprogress':True,
            'quiet':True,
            'prefer_ffmpeg':True,
            'encoding': 'utf-8',
            'cachedir': 'cache/',
            'outtmpl': os.path.realpath(os.path.join(root,'data/videos/%(uploader)s/%(title)s-%(id)s.%(ext)s')),
            'call_home': False,
            'logger': self.logger,
            'format':'bestaudio/audio_only/Audio_Only',
            'skip_download':True,
            'progress_hooks': [ self.progress_hook ]
        }

Now this works as long as neither of the mentions options are true. Now there is no way for the calling script to figure out where the file went.

Now I wonder is this a missing feature or is it by design?

progress_hooks works for video downloading only. In case of skip_download no video is downloaded thus no hooks delivered.

Well then it is a feature request to still get the filename data from the call.

There is a _filename in info dict.
