Abstract

The embodiment of the invention discloses a multi-channel decoder synchronization control method, device and storage medium. Among them, the multi-channel decoder synchronous control method includes: the master decoder performs time synchronization with each slave decoder in the decoder group; Completion message, as well as its own rendering completion time for the next screen of the bound single screen, determine the switching time; the master decoder sends the switching time to each slave decoder, so that each decoder in the decoder grouping can operate under the switching time , to provide the corresponding next screen to the bound single screen for display. The technical solution of the embodiment of the present invention solves the problem of screen tearing caused by asynchronous video streams output from the decoder to the video wall by performing time synchronization operations on the decoders included in the decoder group, so that multiple single The TV wall composed of screens can display smooth images.

Description

technical field [0001] The embodiment of the present invention relates to video and audio decoder control technology, in particular to a multi-channel decoder synchronization control method, device and storage medium. Background technique [0002] With the increasing demand for splicing of physical screens in the fields of security, video surveillance, etc., it is obvious that only a single decoder can not meet the needs of large-screen display. The use of multiple decoders can realize single-screen splicing. Display effects such as opening a window or dragging an image to any position. [0003] In the prior art, when multiple decoders are spliced ​​and used, the following problems are prone to occur: video streams are sequentially input to multiple decoders, resulting in asynchronous output of video streams to the video wall, and inconsistent decoded video stream sizes, resulting in inconsistent decoding time. When there is no time synchronization mechanism between decoder...
