"Allies of the free Codec did not leave this provocative statement uncontested for long: Greg Maxwell from Xiph published a comparison between H.263/H.264 and the current Theora version on his homepage. He came to the conclusion that Theora’s smaller bitrate clearly cuts better than the currently used on Youtube H.263 Codec and the patent protected H.264 Codec. Maxwell also received support from Mozilla developers and Wikimedia fans. David Gerard emphasized that the MPEG LA would begin to charge license fees for streaming with H.264. For this reason, many fear Codec will not indefinitely possess the capability of being used easily anymore. A crucial point on possible alternatives to Theora was brought up by free consultant Silvia Pfeiffer and explained that the danger of a submarine patent in Theora is very low."
