Abstract: A video decoder can be configured to determine that a current block in a current picture of the video data is coded in an affine prediction mode; determine one or more control-point motion vectors (CPMVs) for the current block; identify an initial prediction block for the current block in a reference picture using the one or more CPMVs; determine a current template for the current block in the current picture; and determine an initial reference template for the initial prediction block in the reference picture; and perform a motion vector refinement process to determine a modified prediction block based on a comparison of the current template to the initial reference template.

Abstract: An example device for decoding video data includes one or more processors implemented in circuitry and configured to: generate an inter-prediction block for a current block of video data; generate an intra-prediction block for the current block of video data; generate a final prediction block for the current block of video data from the inter-prediction block and the intra-prediction block, including performing each of combined inter/intra prediction (CIIP) mode, overlapped block motion compensation (OBMC), and luma mapping with chroma scaling (LMCS) while generating the final prediction block; and decode the current block of video data using the final prediction block. To generate the final prediction block, the processors may perform LMCS on a first inter-prediction sub-block, combine the LMCS-mapped first inter-prediction sub-block with the intra-prediction block using CIIP, and perform OBMC between the first CIIP prediction block and a second inter-prediction sub-block.

Abstract: The present invention provides a rotary engine having: a stationary cylinder with an intake aperture, an exhaust aperture, and an ignition aperture on the surface; a driving disk disposed inside the stationary cylinder connected to an external driving source through a shaft, the driving disk being secured to a surface of at least one rotational cylinder that are together driven by the driving source; and a swing piston installed inside the rotational cylinder driven by a driving member to move within the rotational cylinder to alter the intake and exhaust volume of the rotational cylinder. The intake and exhaust volume changes corresponding to the position of the rotational cylinder which follows the intake, ignition, and exhaust sequential process to complete the intake, compression, combustion, and exhaust cycle of an engine to create a simple yet high output, low-friction engine with superior cooling.
