• Downloading youtube mp3 - metadata encoding issue (python, youtube-dl, ffmpeg)

  21 mai 2015, par mopsiok

  I’m trying to download audio from youtube with youtube-dl.exe and ffmpeg.exe (Windows 7), but I am having some troubles with encoding. I have to parse metadata manually, because when I try to use

  --metadata-from-title "%(artist) - %(title)" --extract-audio --audio-format mp3 https://www.youtube.com/watch?v=DaU94Ld3fuM

  I get ERROR : Could not interpret title of video as "%(artist) - %(title)"

  Anyway, I wrote some code to save metadata with ffmpeg :

  def download(url, title_first=False):
  
      if (0 == subprocess.call('youtube-dl --extract-audio --audio-format mp3 %s' % url)):
  
          #saves file in current directory in format: VID_TITLE-VID_ID.mp3
  
          video_id = url[url.find('=')+1:] #video id from URL (after ?v=)
  
          for f in os.listdir('.'):
  
              if video_id in f:
  
                  filename = f
  
                  break
  
          os.rename(filename, video_id+'.mp3') #name without non-ascii chars (for tests)
  
          video_title = filename[: filename.find(video_id)-1]
  
  
  
          output = video_title + '.mp3'
  
          title, artist = '', ''
  
          try: #parsing the title
  
              x = video_title.find('-')
  
              artist = video_title[:x].strip()
  
              title = video_title[x+1:].strip()
  
              if (title_first): output = '%s - %s.mp3' % (title, artist)
  
          except:
  
              pass
  
  
  
          x = 'ffmpeg -i "%s" -metadata title="%s" -metadata artist="%s" -acodec copy -id3v2_version 3 -write_id3v1 1 "%s"' \
  
                          % (video_id+'.mp3', title, artist, output)
  
          print x
  
          subprocess.call(x)

  The file is downloaded and then cropped to given start and duration times (the code above is a simplified version). Filename is fine, but when I open the file with AIMP3, it shows rubbish instead of non-ascii characters :

  

  I’ve tried to re-encode the final command with iso-8859-2, utf-8 and mbcs :

  x = x.decode('cp1250').encode('iso-8859-2')

  But non-ascii chars are still not readable. Passing an unicode command returns UnicodeEncodeError...

  Any idea how to solve this problem ?

• Cloaked Archive Wiki

  16 mai 2011, par Multimedia Mike — General

  Google’s Chrome browser has made me phenomenally lazy. I don’t even attempt to type proper, complete URLs into the address bar anymore. I just type something vaguely related to the address and let the search engine take over. I saw something weird when I used this method to visit Archive Team’s site :

  
  
  

  There’s greater detail when you elect to view more results from the site :

  
  
  

  As the administrator of a MediaWiki installation like the one that archiveteam.org runs on, I was a little worried that they might have a spam problem. However, clicking through to any of those out-of-place pages does not indicate anything related to pharmaceuticals. Viewing source also reveals nothing amiss.

  I quickly deduced that this is a textbook example of website cloaking. This is when a website reports different content to a search engine than it reports to normal web browsers (humans, presumably). General pseudocode :

  PLAIN TEXT

  C :

  1. if (web_request.user_agent_string == CRAWLER_USER_AGENT)
  2.  return cloaked_data ;
  3. else
  4.  return real_data ;

  You can verify this for yourself using the wget command line utility :

  <br />
$ wget --quiet --user-agent="<strong>Mozilla/5.0</strong>" \<br />
 http://www.archiveteam.org/index.php?title=Geocities -O - | grep \&lt;title\&gt;<br />
&lt;title&gt;GeoCities - Archiveteam&lt;/title&gt;

  $ wget —quiet —user-agent="Googlebot/2.1"
  http://www.archiveteam.org/index.php?title=Geocities -O - | grep \<title\>
  <title>Cheap xanax | Online Drug Store, Big Discounts</title>
  

  I guess the little web prank worked because the phaux-pharma stuff got indexed. It makes we wonder if there’s a MediaWiki plugin that does this automatically.

  For extra fun, here’s a site called the CloakingDetector which purports to be able to detect whether a page employs cloaking. This is just one humble observer’s opinion, but I don’t think the site works too well :
