The Alliance for Open Media has recently initiated coding tool exploration activities towards the next-generation video coding beyond AV1. With this regard, this paper presents a package of coding tools that have been investigated, implemented and tested on top of the codebase, known as libaom, which is used for the exploration of next-generation video compression tools. The proposed tools cover several technical areas based on a traditional hybrid video coding structure, including block partitioning, prediction, transform and loop filtering. The proposed coding tools are integrated as a package, and a combined coding gain over AV1 is demonstrated in this paper. Furthermore, to better understand the behavior of each tool, besides the combined coding gain, the tool-on and tool-off tests are also simulated and reported for each individual coding tool. Experimental results show that, compared to libaom, the proposed methods achieve an average 8.0% (up to 22.0%) overall BD-rate reduction for All Intra coding configuration a wide range of image and video content.
