YouTube plans to make AV2 streams available on the web as early as 2027, according to a new Alliance for Open Media ecosystem update. The statement provides a concrete service target four months after publication of the codec's first final specification. YouTube says more than 90% of its catalogue, weighted by watch time, was already available in AV1 by 19 March 2026, giving the platform an established open-codec workflow from which to begin AV2 deployment.
The announcement also moves browser support beyond a roadmap claim. Google has demonstrated native AV2 playback in Chrome, while Netflix and Prime Video are described as exploring the format. Intel is developing the open-source SVT-AV2 encoder, Meta says it intends to carry AV2 through productisation, and AOMedia members are contributing reference software, test streams, compliance tooling, benchmarking and interoperability work. These activities do not amount to one common launch schedule.
AV2 is designed to improve compression efficiency by about 30% over AV1 on objective metrics while adding stronger support for multistream and multiview video, real-time communication, high frame rates and HDR. For large streaming platforms, the significance is a possible reduction in delivery bitrate or an increase in quality at the same bitrate. Multi-video capabilities could also reduce application-level synchronisation work for composite or selectable-view experiences.
Important deployment details remain open. AOMedia and YouTube have not specified which browsers, countries, catalogue segments, resolutions or account groups will enter the first wave. The notice does not give encoder throughput, device power consumption, live-encoding readiness or a hardware-decoder timetable. Early web availability should therefore be read as the start of controlled adoption, not proof that AV2 will replace AV1 across consumer devices in 2027.
