Chinese AVS is a set of standards like MPEG. It consists of:

AVS1-P1 (System for broadcast)

The Samples are said to be in this format, but they are basically MPEG PS files.

AVS1-P2 (Video for HD - JZ an ZQ profiles)

FFmpeg contains a LGPL-licensed decoder for the JZ profile and a patch for a matching encoder has been posted to the FFmpeg development mailing list. GPL video decoders for the JZ profile are available from http://cosoft.org.cn/projects/avsdec/ and the OpenAVS project on SourceForge. Reference software can be found at http://www.avs.org.cn/fruits/software/rm52j_r1.zip. This video codec has many similarities to H.264 while avoiding the most complex features like CABAC or MBAFF.

AVS1-P3 (Audio, 2 and 5.1 channels)

AVS1-P6 (DRM)

Recently China announced a new effort to start its own High Definition disc format, called CBHD. This includes AVS DRM and video specification according to news sources

AVS1-P8 (Video for mobile)

AVS1-P9 (File format)

The Windows transcoder is said to produce files in this format, but the resulting files are basically of ISO 14496-12 format.

General

For now only the AVS1-P1 and AVS1-P2 JZ profile are standardized, other parts are still in the works.
