Today we are excited to announce that Netflix has started streaming AV1 to our Android mobile app. AV1 is a high performance, royalty-free video codec that provides 20% improved compression efficiency over our VP9 encodes. AV1 is made possible by the wide-ranging industry commitment of expertise and intellectual property within the Alliance for Open Media (AOMedia), of which Netflix is a founding member.
