HDR Vivid video decoding post-processing method and decoder

The invention discloses an HDRVivid video decoding post-processing method and a decoder, and the method comprises the following steps: dividing YUV data to be post-processed into N Slices, N being set according to the equipment capability and the image size; creating and applying for an output frame V210 storage memory block; gPU resources are abstracted into different capability types, including H2D copy, CU general computation and D2H copy; creating an independent thread module to carry out HDRVivid mapping curve parameter generation calculation; applying for H2D copy capability resources, and executing the operation of copying the YUV data from the memory to the video memory; acquiring an HDRVivid curve parameter generation result of the current frame from a curve parameter generation module; applying for CU general computing power resources, and executing a Vivid post-processing core computing process; applying for a D2H copying capability, and executing an operation of copying V210 data from a video memo
