Perhaps they will never be included. Standards like libav and FFMPEG are American. To break free from U.S. standards and dependencies, China has developed its own set of coding standards—AVS3, AVS2, AVS+. And the U.S. intent on maintaining its monopoly over its own standards, will probably never incorporate China’s proprietary video codecs.
Sure, it would be ideal to support everything, but there is a limit on time I can spend on this.
I adjusted the ffmpeg build to include:
- ibdavs2 AVS2-P2/IEEE1857.4 (codec avs2)
- libuavs3d AVS3-P2/IEEE1857.10 (codec avs3)
- cavs Chinese AVS (Audio Video Standard) (AVS1-P2, JiZhun profile)

ffmpeg can't decode more than those projects.
If you want more support in Hybrid through ffmpeg get those projects to support your content.
If there are other open source sources for these or other libraries that could be used. Let the folks over at
https://github.com/m-ab-s/media-autobuild_suite know maybe they include them.

thank you, i'm downloading Hybrid_dev_2025.10.25-192032.exe for using.
indeed, it's great news, looking forward to it.
I learn that AVS3 encoding is used for 8K video, AVS2 encoding is used for 4K video, and AVS+ is used for satellite broadcasting, the 1080i video.
