Problems solved by technology

[0002] When playing video files on terminal devices, monitoring playback, and playing historical videos in the recording and broadcasting system, it is necessary to perform buffer loading first. Whether it is forward buffer loading or backward buffer loading, it will take a certain amount of time to buffer, so , if you want to locate the target location to be played, if the network condition is not good, it will take more time and the positioning will be slower

Embodiment Construction

[0047] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The I frame is an Intra-coded picture (intra-coded image frame), which does not refer to other image frames, and only uses the information of this frame for encoding.

[0049] The P frame is the Predictive-coded Picture (predictive coded image frame), which uses the previous I frame or P frame to perform inter-frame predictive coding by means of motion prediction.

[0050] The B frame is the Bidirectionally predicted picture (bidirectionally predictively encoded image frame), which provides the highest compression ratio.

[0051] PTS: The time scale of the frame display (at which point in time this frame is displayed).

[0052] DTS: The time scale of frame decoding (at which point in time this frame is decoded).

Abstract

The embodiment of the invention provides a video processing method and device, terminal equipment and a storage medium, and the method comprises the steps: receiving a video positioning instruction, and obtaining the first video time of a to-be-positioned video from the video positioning instruction; determining a second video time set meeting a preset condition according to the first video time and a pre-stored time sequence corresponding relation; wherein the pre-stored time sequence corresponding relation comprises the frame image information and the video time corresponding to the frame image information; determining second video time closest to the time interval of the first video time in the second video time set as target video time; according to the method, the target video frame corresponding to the target video time is determined according to the target video time, and the target video frame is sent to the front-end equipment to be displayed, so that the video target position is quickly positioned by judging the video time sequence, the video backward or forward cache time is reduced, and the positioning efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method, device, terminal equipment and storage medium. Background technique [0002] When playing video files on terminal devices, monitoring playback, and playing historical videos in the recording and broadcasting system, it is necessary to perform buffer loading first. Whether it is forward buffer loading or backward buffer loading, it will take a certain amount of time to buffer, so , if you want to locate the target location to be played, if the network condition is not good, it will take more time and the positioning will be slower. Contents of the invention [0003] In view of the above problems, embodiments of the present invention are proposed to provide a video processing method, device, terminal device, and storage medium that overcome the above problems or at least partially solve the above problems. [0004] In a first aspect, a...
