Video transcoding gateway, monitoring system and transcoding method for video transcoding gateway

Abstract

The invention relates to the technical field of video transcoding, and provides a video transcoding gateway, which comprises a management module, a transcoding module and a network module. A video transcoding gateway monitoring system comprises a monitoring platform, a terminal and the video transcoding gateway. A transcoding method for the video transcoding gateway comprises the following steps of S11.adopting the management module to manage the transcoding module and the network module, and the start or stop of a transcoding task; S12.adopting the transcoding module to analyze a format of anetwork video stream and carry out decoding and coding; and S13.adopting the network module to receive and send the network video stream and feed a packet receiving condition of a client back in time.Hardware acceleration transcoding is adopted, and the format of the network video stream is analyzed through the transcoding module, so that the real-time performance, the continuity and the stability of the video stream in a transmission process can be ensured; compared with an existing GPU, a zero-copy mode is adopted, video frame decoding and coding can be completed in a display memory, the memory copying cost is saved, and the transcoding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of video transcoding, in particular to a video transcoding gateway. Background technique [0002] In recent years, my country's overall economic strength has been significantly enhanced, but the social security situation has become increasingly complex, public security issues have become increasingly prominent, urban crimes have become prominent, and methods have been constantly updated and upgraded. These are urgently required to speed up the development of video surveillance systems that focus on active prevention. [0003] From a technical point of view, the current development trend of urban security systems is mainly reflected in the following points: [0004] Clearer video quality. With the great improvement of digital image acquisition performance, terminal display capabilities have also improved accordingly. HDTV video has reached 1920X1080, 4K, so the mainstream image quality of video surveillance...
