Problems solved by technology

[0003] Currently existing 264 format video players can only play one video. If you need to compare the differences between two video screens, you need to play them repeatedly, or use multiple monitors to display them at the same time.

Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:

[0034] The multi-channel video decoding and display method based on H.264 provided by the present invention specifically adopts the following technical scheme, see figure 1 , including the following steps:

[0035] ① Select the playback window, if there are multiple playback windows to choose from, the default is the first playback window;

[0036] ②Select the video file to be played;

[0037] ③ Determine whether the video playback status of the current window is stopped, if so, proceed to the next step, otherwise stop the video being played in this window first, and then proceed to the next step;

[0038] ④ Obtain the path and name of the selected video file, and display it at the specified location on the screen;

[0039] ⑤Create a corresponding playback thread according to the selected window number, which is used to play and display the vide...

Abstract

The invention relates to the technical field of video decoding, in particular to multichannel video decoding display method and system based on H.264. The multichannel video decoding display method comprises the following steps: selecting a playing window, selecting a video file to be played, judging whether the video playing state of the current window is stopped or not, if so, executing the nextstep, if not, stopping playing video in the window, then executing the next step, obtaining a path and a name of a selected video file, displaying the path and the name on appointed positions of a screen, creating a corresponding playing process used for displaying and playing the video file at the selected window position according to a selected window number, judging whether a new video file tobe played exists or not, if so, executing the first step, if not, executing the next step, and executing a playing process function. The invention realizes synchronous playing and respective controlof the multichannel video, can realize synchronous playing and displaying and respective control of multichannel video code streams, is convenient to look up and compare the video file and achieves the motion detection alarm function.

Description

technical field [0001] The present invention relates to the technical field of video coding and decoding, in particular to an H.264-based multi-channel video decoding and display method and system. Background technique [0002] In recent years, with the development of digital codec technology and network technology, people have more and more demands for multimedia signals, and the required quality is also getting higher and higher. As a new generation of video coding standards for multimedia applications, technically, H.264 uses intra-frame prediction, unified VLC symbol coding, high-precision, multi-mode motion estimation, integer transform coding, layered coding syntax, etc. technology, which makes H.264 successful in terms of coding efficiency, image quality, network adaptability and error resistance. At the same time, these advantages will inevitably make it widely used in popular fields such as digital broadcasting and television, video mobile communication, digital vi...
