Into the Depths: The Technical Details Behind AV1
AV1, the next generation royalty-free video codec from the Alliance for Open Media leapfrogs the performance of VP9 and HEVC. The AV1 format is and will always be royalty-free with a permissive FOSS license. In this video presentation, Mozilla's Nathan Egge dives deep into the technical details of the codec and its evolution.

AV1 and the Video Wars of 2027
This post imagines a dystopian future where only the rich can stream video to their homes, and the democratizing forces of the internet have crumbled under corruption and greed. The author reports back from a troubled future in the late 2020s that is wholly fictitious. The open video codec AV1 is wholly real.

AV1: next generation video – The Constrained Directional Enhancement Filter
AV1 is a new general-purpose video codec developed by the Alliance for Open Media. The alliance began development of the new codec using Google’s VPX codecs, Cisco’s Thor codec, and Mozilla’s/Xiph.Org’s Daala codec as a starting point. AV1 leapfrogs the performance of VP9 and HEVC, making it a next-next-generation codec. Today's post is a deep-dive into the Constrained Directional Enhancement Filter and how it came to be.

DASH playback of AV1 video in Firefox
Bitmovin and Mozilla, both members of the Alliance for Open Media (AOM), are partnering to bring AV1 playback with HTML5 to Firefox as the first browser to play AV1 MPEG-DASH/HLS streams. To make playback possible while the AV1 bitstream is still being finalized, we just need to ensure that the encoder and decoder use the same version of the bitstream. Bitmovin and Mozilla agreed on a simple, but for the time being useful, codec string, to ensure compatibility - check out the playback demo to see for yourself.

WebAssembly Will Ease Collaboration on Next Generation Video Codecs
WebAssembly is a new, low-level format for programs on the Web being developed by Mozilla, Microsoft, Google, and Apple, so it will eventually work in all browsers. This post explores how WebAssembly will play an integral role in the development of next generation video codecs. The new workflow represents a fundamental shift in Web development: The wall between “native” and the Web is falling, opening the door to dramatically greater performance on the Web.
