Abstract

The invention discloses a method and system for achieving the transcoding task scheduling, and relates to the field of video transcoding. The method comprises the steps: carrying out the statistics of the current total coding capability Es and total decoding capability Ds of a GPU card set; judging whether the total coding capability Es is matched with the total decoding capability Ds or not; adjusting the coding or decoding capability of a corresponding GPU card in the GPU card set if the total coding capability Es is not matched with the total decoding capability Ds, so as to enable the total coding capability Es of the GPU card set to be matched with the total decoding capability Ds. According to the invention, the coding and decoding capabilities of the GPU card are separated for calculation, and the method carries out the task scheduling based on a coding and decoding capability matching principle through combining with the correlation of the coding and decoding capabilities, can make the most of the capability of the GPU, and achieves the maximum throughput of a transcoding task.

Description

technical field [0001] The invention relates to the field of video transcoding, in particular to a method and system for implementing transcoding task scheduling. Background technique [0002] In the video transcoding task, decoding and encoding are producer-consumer relationships, and decoding and encoding capabilities must match. In reality, GPU cards have asymmetry in encoding and decoding capabilities. The ratio of encoding and decoding capabilities of some GPU cards alone is 1:3, while the encoding capabilities of some GPU cards equipped with dedicated encoding circuits may be equivalent to or even better than decoding capabilities. powerful. In addition, when the GPU card executes encoding and decoding at the same time, the encoding and decoding capabilities are affected. According to the test results, when the GPU card encodes and decodes at the same time, the relationship between decoding and encoding is as follows: figure 1 shown. The abscissa is k d , the vert...
