 FAQ

+How do I update youtube-dl?
+
+If you've followed our manual installation instructions, you can simply
+run youtube-dl -U (or, on Linux, sudo youtube-dl -U).
+
+If you have used pip, a simple sudo pip install -U youtube-dl is
+sufficient to update.
+
+If you have installed youtube-dl using a package manager like apt-get or
+yum, use the standard system update mechanism to update. Note that
+distribution packages are often outdated. As a rule of thumb, youtube-dl
+releases at least once a month, and often weekly or even daily. Simply
+go to http://yt-dl.org/ to find out the current version. Unfortunately,
+there is nothing we youtube-dl developers can do if your distributions
+serves a really outdated version. You can (and should) complain to your
+distribution in their bugtracker or support forum.
+
+As a last resort, you can also uninstall the version installed by your
+package manager and follow our manual installation instructions. For
+that, remove the distribution's package, with a line like
+
+    sudo apt-get remove -y youtube-dl
+
+Afterwards, simply follow our manual installation instructions:
+
+    sudo wget https://yt-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
+    sudo chmod a+x /usr/local/bin/youtube-dl
+    hash -r
+
+Again, from then on you'll be able to update with sudo youtube-dl -U.
+
+I'm getting an error Unable to extract OpenGraph title on YouTube playlists
+
+YouTube changed their playlist format in March 2014 and later on, so
+you'll need at least youtube-dl 2014.07.25 to download all YouTube
+videos.
+
+If you have installed youtube-dl with a package manager, pip, setup.py
+or a tarball, please use that to update. Note that Ubuntu packages do
+not seem to get updated anymore. Since we are not affiliated with
+Ubuntu, there is little we can do. Feel free to report bugs to the
+Ubuntu packaging guys - all they have to do is update the package to a
+somewhat recent version. See above for a way to update.
+
+Do I always have to pass in --max-quality FORMAT, or -citw?
+
+By default, youtube-dl intends to have the best options (incidentally,
+if you have a convincing case that these should be different, please
+file an issue where you explain that). Therefore, it is unnecessary and
+sometimes harmful to copy long option strings from webpages. In
+particular, --max-quality limits the video quality (so if you want the
+best quality, do NOT pass it in), and the only option out of -citw that
+is regularly useful is -i.
+

 Can you please put the -b option back?

+EMBEDDING YOUTUBE-DL
+====================
+
+youtube-dl makes the best effort to be a good command-line program, and
+thus should be callable from any programming language. If you encounter
+any problems parsing its output, feel free to create a report.
+
+From a Python program, you can embed youtube-dl in a more powerful
+fashion, like this:
+
+    import youtube_dl
+
+    ydl_opts = {}
+    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
+        ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+
+Most likely, you'll want to use various options. For a list of what can
+be done, have a look at youtube_dl/YoutubeDL.py. For a start, if you
+want to intercept youtube-dl's output, set a logger object.
