H.264

H.264 is restricted by patents owned by various parties. A license covering most (but not all) patents essential to H.264 is administered by a patent pool formerly administered by MPEG LA. Via Licensing Corp acquired MPEG LA in April 2023 and formed a new patent pool administration company called Via Licensing Alliance. The commercial use of patented H.264 technologies requires the payment of royalties to Via and other patent owners. MPEG LA has allowed the free use of H.264 technologies for streaming Internet video that is free to end users, and Cisco paid royalties to MPEG LA on behalf of the users of binaries for its open source H.264 encoder openH264.
