Codec Working Group

The Codec Working Group (CWG) is tasked with creating next-generation royalty-free video coding technology. The first deliverable from the CWG was the AV1 Bitstream & Decoding Process specification, and corresponding libaom reference code, published in June 2018.

Current main focus areas:

  • Maintenance of the AV1 specification.
  • Maintenance & improvement of the AV1 reference software (libaom).
  • Exploration of new image & video codec technologies, beyond AV1.

Software Implementation Working Group

The Software Implementation Working Group (SIWG) is responsible for creating software encoder implementations that are optimized to deliver excellent video compression at complexities compatible with deployment in an extensive range of video delivery use-cases. The work of the SIWG leverages the SVT-AV1 codebase, together with the research work done in the Codec Working Group, to develop production-ready encoders for all AOMedia video codecs.

Storage and Transport Formats Working Group

The Storage and Transport Formats Working Group (STFWG) is responsible for the development and maintenance of specifications and associated reference code in the following areas:

  • Storage and transport formats for media data and time-aligned media-associated metadata
  • Signaling for the combination of media, including synchronization
  • Signaling for the protection of media
  • Signaling for the rendering of media
  • Management of ITU-T T.35 AOMedia Matadata payloads for codec-agnostic, time-aligned media-associated metadata

This includes the development and maintenance of specifications such as the AV1 image format (AVIF), the carriage of AV1 video streams in ISOBMFF & CMAF, and the carriage of AV1 in an MPEG-2 TS.

Volumetric Visual Media Working Group

The Volumetric Visual Media (VVM) working group develops specifications for the efficient coding and the support of streaming of Immersive/Volumetric Visual Media considering broadcast, download, and interactive applications. The group focuses mainly on developing compression technologies that could be integrated with any scene graph representation.

The group is currently focusing on static 3D polygonal mesh compression, and static 3D point cloud compression.
