Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. For ease of description, only the parts related to the embodiments of the present invention are shown. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0032] In the method of the present invention, the transcoding server has two or more CPU cores, and a static stress test is performed on the transcoding server before the scheduling scheme is implemented, and the maximum number of concurrent transcoding tasks that a single CPU core can bear is measured; scheduling At the beginning of the implementation of the scheme, initialize the number of currently executing tasks of all CPU cores to 0, and judge that if a new transcoding task ...

Abstract

The invention discloses a multi-core CPU video transcoding scheduling method, which belongs to the field of video transcoding. Before a scheduling scheme is implemented, a static pressure test is carried out for a transcoding server in order to measure the maximum concurrent transcoding task number of a single CPU core; the scheduling scheme is started; the number of currently executed tasks of all the CPU cores is initialized as 0; if a new transcoding task arrives, then scheduling is carried out according to an allocation and scheduling method for new tasks; if a transcoding task is stopped, then scheduling is carried out according to an allocation and scheduling method for existing tasks; if a message for stopping all transcoding tasks is received, then a program is closed, and otherwise, the method rejudges whether a new transcoding task arrives, and carries out circular processing. The invention ensures that the transcoding tasks can be operated in the same CPU core to the greatest extent, thus effectively increasing the hit rate of the CPU cache and the operation efficiency of the system, and moreover, the loads of all the CPU cores can be balanced to the greatest extent.

Description

technical field [0001] The present invention relates to the field of video transcoding, in particular to a multi-core CPU video transcoding scheduling method [0002] and system. Background technique [0003] At present, there are a large number of network surveillance video streams in the fields of transportation, security, production monitoring, and environmental protection. These video streams generally have higher resolution and higher bit rate in order to record on-site conditions in more detail. However, with the development of the mobile Internet, people hope that they can also conveniently watch the remote on-site situation through their mobile phones. Due to the limited bandwidth of mobile channel transmission and the weak decoding ability of mobile terminals, it is necessary to transcode the original surveillance video stream to reduce the resolution, frame rate, bit rate and other parameters of the video, so that the video can be smoother It is transmitted on t...
