Dear Sir or Madam:

I am contacting you on behalf of the Recording Industry Association of
America, Inc. (RIAA) and its member record companies. The RIAA is a
trade association whose member companies create, manufacture or
distribute sound recordings representing approximately eighty-five
(85) percent of all legitimate recorded music consumption in the
United States. Under penalty of perjury, we submit that the RIAA is
authorized to act on behalf of its member companies on matters
involving the infringement of their sound recordings, audiovisual
works and images, including enforcing their copyrights and common law
rights on the Internet.

Copyright Violations. We have learned that your service is hosting the
youtube-dl source code on its network at the following locations,
among others: [private]

The above list includes a representative sample of the youtube-dl
forks of the youtube-dl source code being hosted on GitHub. Based on
our review of the representative sample noted above, we have a good
faith belief that most of the youtube-dl forks are infringing to the
same extent as the parent repository.

The clear purpose of this source code is to (i) circumvent the
technological protection measures used by authorized streaming
services such as YouTube, and (ii) reproduce and distribute music
videos and sound recordings owned by our member companies without
authorization for such use. We note that the source code is described
on GitHub as “a command-line program to download videos from and a few more sites.”1

We also note that the source code prominently includes as sample uses
of the source code the downloading of copies of our members’
copyrighted sound recordings and music videos, as noted in Exhibit A

  1. For example, as shown on Exhibit A, the source code expressly
  2. its use to copy and/or distribute the following copyrighted

works owned by our member companies:

• Icona Pop – I Love It (feat. Charli XCX) [Official Video], owned by
Warner Music Group • Justin Timberlake – Tunnel Vision (Explicit),
owned by Sony Music Group • Taylor Swift – Shake it Off,
owned/exclusively licensed by Universal Music Group

The source code notes that the Icona Pop work identified above is
under the YouTube Standard license, which expressly restricts access
to copyrighted works only for streaming on YouTube and prohibits their
further reproduction or distribution without consent of the copyright
owner; that the Justin Timberlake work identified above is under an
additional age protection identifier; and that the request for the
Taylor Swift work identified above is to obtain, without authorization
of the copyright owner or YouTube, an M4A audio file from the
audiovisual work in question.

We have a good faith belief that this activity is not authorized by
the copyright owner, its agent, or the law. We assert that the
information in this notification is accurate, based upon the data
available to us.

Anticircumvention Violation. We also note that the provision or
trafficking of the source code violates 17 USC §§1201(a)(2) and
1201(b)(1). The source code is a technology primarily designed or
produced for the purpose of, and marketed for, circumventing a
technological measure that effectively controls access to copyrighted
sound recordings on YouTube, including copyrighted sound recordings
owned by our members. For further context, please see the attached
court decision from the Hamburg Regional Court that describes the
technological measure at issue (known as YouTube’s “rolling cipher”),
and the court’s determination that the technology employed by YouTube
is an effective technical measure within the meaning of EU

1 See

and German law, which is materially identical to Title 17 U.S.C. §1201
of the United States Code. The court further determined that the
service at issue in that case unlawfully circumvented YouTube’s
rolling cipher technical protection measure.2 The youtube-dl source
code functions in a manner essentially identical to the service at
issue in the Hamburg Regional Court decision. As there, the youtube-dl
source code available on Github (which is the subject of this notice)
circumvents YouTube’s rolling cipher to gain unauthorized access to
copyrighted audio files, in violation of YouTube’s express terms of
service,3 and in plain violation of Section 1201 of the Digital
Millennium Copyright Act, 17 U.S.C. §1201.

Indeed, the comments in the youtube-dl source code make clear that the
source code was designed and is marketed for the purpose of
circumventing YouTube’s technological measures to enable unauthorized
access to our member’s copyrighted works, and to make unauthorized
copies and distributions thereof: they identify our member’s works,
they note that the works are VEVO videos (virtually all of which are
owned by our member companies), they acknowledge the those works are
licensed to YouTube under the YouTube standard license, and they use
those examples in the source code to describe how to obtain
unauthorized access to copies of our members’ works.

In light of the above noted copyright infringements and
anticircumvention violations, we ask that you immediately take down
and disable access to the youtube-dl source code at all of its
locations where it is hosted on GitHub, including without limitation
those locations in the representative list set forth above.

This e-mail does not constitute a waiver of any right to recover
damages incurred by virtue of any such unauthorized activities, and
all such rights as well as claims for other relief are expressly

You may contact me at RIAA, [private] Tel. [private], or email
[private] to discuss this notice.

Sincerely, [private] [private]
