Abstract

The invention provides a live video transcoding method and device. The live video transcoding method comprises the following steps: counting the number of watching people of a live video at the current moment; calculating a metric value of the live video according to the time period to which the current moment belongs and the number of viewers; and transcoding the source stream of the live video by using a target transcoding rule corresponding to a target threshold value under the condition that the metric value reaches the target threshold value in the corresponding relationship according to the corresponding relationship between the preset threshold value and the transcoding rule. According to the scheme, the bandwidth cost of the computing resources and the live video can be balanced.

Description

technical field [0001] The present application relates to the technical field of video transcoding, in particular to a live video transcoding method. The present application also relates to a live video transcoding device, a computing device, and a computer-readable storage medium. Background technique [0002] During a live broadcast, the anchor client usually pushes a source stream with a high bit rate, which tends to occupy a large amount of bandwidth and cause the live broadcast to freeze. In order to reduce the cost of bandwidth and the frequency of live broadcast stuttering, the server can transcode the source stream pushed by the anchor client to generate a low-bit-rate high-definition video stream. [0003] However, transcoding requires a lot of computing resources, and computing resources are limited. Therefore, it is not possible to directly transcode the source streams of all live videos in order to reduce bandwidth costs. It can be seen that how to balance comp...
