AV1 – Video Codec. High-quality Video Without Paying Royalty Fees

What is AV1?

AV1 is a new video codec that promises to help companies and individuals transmit high-quality video over the internet efficiently, without paying royalty fees.

AV1 is the first project to come out of the Alliance for Open Media (AOMedia), a consortium that promotes media codecs, formats, and technologies for the public web. Mozilla joined AOMedia in 2015 as a founding member. Mozilla sponsors open media codecs like AV1 because they have the potential to remove technical and financial barriers for people who want to create and share high-quality media experiences on the open web platform.

How is AV1 different? What will it replace or change?

The most popular video format in use today is AVC/H.264. That technology was introduced in 2003 and is owned by the Moving Picture Experts Group (MPEG).

AV1 is different from AVC/H.264 because it:

  • Uses next-generation compression technology that is nearly twice as efficient
  • Can transmit high-quality video faster over the internet
  • Has no licensing fees; anyone can compress and decode video files without paying royalties
  • Can deliver higher-quality experiences to end users, even when bandwidth is constrained

MPEG has created a successor to AVC/H.264, known as HEVC (High Efficiency Video Coding) or H.265, which has improved compression. However, uncertainty around HEVC’s licensing fees make it untenable for both web browsers and content creators.

The goal of the AV1 project is to replace AVC/H.264 as the predominant video format for the web and to compete with the HEVC codec, so high-quality video can be shared freely and efficiently on the open web platform.

Where did AV1 come from?

During the last six years, a number of companies launched projects to create viable alternatives to patented video codecs. Mozilla started work on the Daala Project, Google released VP9, and Cisco created Thor for low-complexity video conferencing. All these efforts had the same goal: to create a next-generation video compression format that would make sharing high-quality video over the internet faster, easier, and cheaper.

In 2015, Mozilla, Google, and Cisco, and others joined with Amazon and Netflix and hardware vendors AMD, ARM, Intel, and NVIDIA to form AOMedia. As AOMedia grew, efforts to create an open video format coalesced around a new codec: AV1. AV1 is based largely on Google’s VP9 and incorporates tools and technologies from Daala, Thor, and VP10.

What’s at stake?

The current AVC/H.264 video codec cannot efficiently support higher-quality video on the web. HEVC/H.265 promises better efficiency for streaming video on demand. However, the many patent holders in HEVC/H.265 could drive costs up, making it prohibitively expensive for many companies to actually use this next-generation codec. Content creators would also need to license HEVC, which could limit its use to a select few.

What’s next?

Browser vendors are expected to begin adding support for AV1 to desktop browsers in 2018, for use with popular websites. News articles predict AV1 may appear in game consoles, set-top boxes, and other devices in 2019. Hardware companies may start embedding AV1 technology into processors and graphics cards in 2020, enabling broader decoding of AV1 video files in a wide variety of devices.
