Abstract: In some embodiments, a mesh encoder encodes a dynamic mesh with efficient geometry coding. The encoder normalizes and integerizes the coordinates of vertices of a mesh frame. The encoder segments the integerized coordinates for the vertices into 3D sub-blocks, each 3D sub-block containing at least one vertex and local coordinates of vertices in each 3D sub-block having a value range fitting into a video bit depth. For each 3D sub-block, the encoder converts coordinates of a vertex inside the 3D sub-block to a local coordinate system of the 3D sub-block and maps each vertex inside the 3D sub-block to a corresponding 2D patch in a geometry component image that represents the mesh frame. The encoder compresses the geometry component image to generate a geometry component bitstream and further generates the coded mesh bitstream for the dynamic mesh by including the geometry component bitstream.

Abstract: A decoding method, system and storage medium are disclosed. In the method, a video decoder decodes a video from a bitstream of the video. The video decoder decodes, from the bitstream, an additional bit count M indicating a quantity of additional general constraints information (GCI) bits included in the bitstream. The additional bits include flag bits indicating respective additional coding tools to be constrained for the video, and an expected value of the additional bit count is 0, 6 or greater than 6. The decoder decodes M?6 bits that follow six flag bits in the bitstream in response to determining that the decoded additional bit count M is greater than 6. The decoder further decodes the remaining portion of the bitstream into images independent of the decoded M?6 bits and based, at least in part, upon constraints specified for the respective additional coding tools by the six flag bits.

Abstract: A video encoder or decoder reconstructs a block of a video coded according to AOM Enhanced Compression Model (AV2) through dependent quantization. The video encoder or decoder accesses quantized samples associated with the block and processes the quantized samples according to an order for the block to generate respective de-quantized samples. Each quantized sample is associated with context-coded syntax elements and at least one quantized sample is associated with bypass-coded syntax elements. The processing includes obtaining a current quantized sample of the block from the quantized samples and determining a quantizer for the current quantized sample based on a parity of a partial quantization level value represented by context-coded syntax elements of a previous quantized sample. The processing further includes de-quantizing the current quantized sample based on the quantizer to generate a dequantized sample. The video encoder or decoder reconstructs the block based on the de-quantized samples.

Abstract: Particular embodiments may remove a condition check in the semantics for checking a high-precision data flag. This simplifies the semantics used in the encoding and decoding process. In this case, even if the high-precision data flag is not set, the value of the weighted prediction syntax element is set by the BitDepth variable. However, even if the BitDepth is not considered high-precision data, such as 8 bits, the range for the weighted prediction syntax element is still the same as the fixed value. For example, the syntax elements luma_offset_l0[i], luma_offset_l1[i], delta_chroma_offset_l0[i][j], and delta_chroma_offset_l1[i][j] use the variable BitDepth as described above whether the flag extended_precision_processing_flag is enabled and not enabled to indicate whether the bit depth is above a threshold.
