The European Commission, which acts as the competition enforcer for the 27-country bloc, had been investigating alleged anti-competitive behaviour related to the license terms of AOM's new standard software for streaming called AV1 since last year.

"The Alliance for Open Media (AOMedia) welcomes the news that the European Commission has today closed its preliminary review of AOMedia's royalty-free licensing policy without further action," AOM said in a statement.

AOM's members include Alphabet unit Google, Amazon, Apple and Meta.
