The invention provides an intra-frame flicker reduction method for parallel efficient video coding, relates to an intra-frame flicker reduction method, and solves the problems that video coding has MPEG-2 (Moving Picture Experts Group-2), the bit rate and QP (quantization parameters) are changed to adapt to the change of network bandwidth in adaptive streaming media transmission, different forecasting modes appear at a GOP (Group of Picture) boundary and parallel efficient video coding is produced. The method comprises the steps of 1, detecting and determining a GOP structure; 2, allocating node tasks NTs to the detected and determined GOP by using a flicker reducing parallel efficient distributed video coding structure; 3, determining a coding unit (CU) with a flicker tendency; and 4, reducing flicker by the determined CU with the flicker tendency. The method is applied in the field of intra-frame flicker reduction.
