OpenAVS
From Wikipedia, the free encyclopedia
OpenAVS [1] is an open source implementaion of AVS or Advanced Coding of Audio and Video). AVS competes with other modern codecs like H.264/AAC/Vorbis [2] to replace MPEG-2 as the most widespread standard for audio and video compression. It is speculated that OpenAVS will go the same direction as X264 has gone aiming for the most superior picture quality, but does not provide an encoder yet. Chinese companies own 90% patents of AVS. [3] [4] It will have twice the efficiency of MPEG2. The audio and video files have an .avs extension as a container format.
In January 2005, the AVS workgroup submitted the draft report to the Information Industry Department. On March 30th, the first trial of Information Industry Department approved that the video part of the draft standard enters the public showing time.
A early command-line based encoder is available for download which is in looks approximately equivalent of DivX 5.0 video. OpenAVS has 64 kbit/s equivalent audio quality of mp3 at 128 kbit/s.
