Abstract
AV1 is an emerging open-source and royalty-free video compression format, which is jointly developed and finalized in June 2018 by the Alliance for Open Media (AOMedia) industry consortium. AV1 achieves significant improvements in coding efficiency compared with HECV and VP9 thanks to new coding tools. However, encoding complexity is extremely high by selecting best mode among new features. This paper proposes a fast chroma prediction mode decision algorithm based on luma prediction mode for AV1 intra coding. Experiment results show that the proposed algorithm achieves an 15.86% TS with 0.44% BDBR increase compared with AV1 reference software.
