Hi there, I'm grad to announce that we, Moore Threads, have finished Chinese AVS&AVS2 hwaccel decoding under FFMpeg-VAAPI framework. As mentioned before in #664, all our public products, MTT S10/MTT S50/MTT S80/MTT S2000/... support AVS&AVS+ decoding at max 2K and support AVS2 Main&Main10 decoding at max 8K. This PR is the patches for libva. For FFmpeg implementaion, please refer to I will also submit the corresponding patches to FFMpeg lately. Thanks, |

Sorry, our driver is currently not open source.
AVS/AVS2 spec and reference decoder can be retrieved from
http://www.avs.org.cn/index/list?catid=7.
For AVS2, there is an open source decoder, [davs2](
https://github.com/pkuvcl/davs2), implemented by Chinese [Peking
University](https://www.pku.edu.cn/). `davs2` has been integrated into
FFMpeg as a 3rd-party decoder.

Is there open source driver available which supports AVS and AVS2?

I am ok to accept the AVS and AVS2 decode interfaces, but how to guarantee the usage? and guarantee the health, looks there are no open source project are using it, and no test application , no test coverage? |
@XinfengZhang Please see intel/libva-utils#346, As mentioned, we also implemented ffmpeg-vaapi decoding for AVS and AVS2. Please see gitgjogh/FFmpeg#1. The PR would be submmitted to FFMpeg devel after this PR being accepted. |

Is skip_mode_flag_flag a typo ? I guess it should be skip_mode_flag.

Could you add code to dump each field in avs2 buffer ?
