WebIn this paper, we focus primarily on new tools in AV1 that improve the prediction of pixel blocks before transforms, quantization and entropy coding are invoked. Specifically, we describe tools and coding modes that improve intra, inter and combined inter-intra prediction. Results are presented on standard test sets. 展开 关键词： WebThis disclosure relates transform configuration and signaling for a compound inter intra prediction modes. In one example, a method for decoding a video block in a video stream is
