python - YoutubeDL - How to get a status object after download has completed -

-

i'm trying information out of seems status object that's hitting hook in youtube-dl, , i'm trying save db. i've got 'song' object attributes such "filename" i'm trying save once download complete, , maybe continually update database progress.

there's 4 ways can think of i've not been able them work

  • send my_hook function db , song object , save in there once status == finished. problem i'm unable pass additional parameters hook unless i'm missing something
  • get my_hook function return d , save that, problem don't think can access return (youtube-dl source)
  • get ydl.download([song.url]) return status object can process, don't think though
  • i don't want this, can output .json file , there, or guess name of file given i'm dictating :(

code looks this:

def my_hook(d):     if d['status'] == 'finished':         file_tuple = os.path.split(os.path.abspath(d['filename']))         print("done downloading {}".format(file_tuple[1]))     if d['status'] == 'downloading':         print(d['filename'], d['_percent_str'], d['_eta_str'])  class mylogger(object):     def debug(self, msg):         pass      def warning(self, msg):         pass      def error(self, msg):         print(msg)   class downloader(object):     def get_opts(self):         ydl_opts = {             'format': 'bestaudio/best',             'outtmpl': os.path.join(app.config['videos_folder'], '%(id)s.%(ext)s'),             'logger': mylogger(),             'progress_hooks': [my_hook],         }         return ydl_opts      def download(self, song):         ydl = youtube_dl.youtubedl(self.get_opts())         ydl.download([song.url])

i got answer here: https://github.com/rg3/youtube-dl/issues/7120

basically 1 many model of song files song requests wrong - rewriting relationship allowed me use hook db updates.
