Embodiment Construction

[0011] The specific embodiments now further illustrate the present invention.

[0012] As a specific embodiment, a video playback method includes the following steps:

[0013] Encode the video data, and perform I frame encoding and P frame encoding at the same time. The reference frame of P frame encoding is the last frame of the previous data frame. The face in the video data is recognized and the face corresponds to The human body frame is individually coded, and the body frame code is stored in the memory,

[0014] When receiving a playback request, corresponding to the playback request, first obtain the data frame information of the playback time node, and both the I frame and P frame of the data frame are returned to the client.

[0015] At the same time, the position information of the human body frame is retrieved from the memory and output to the client, and the position of the human body frame can be moved during the playback of the data frame after receiving the touch signal...

Abstract

The invention relates to the technical field of video processing, in particular to a video playback method. The method comprises steps as follows: video data are encoded, I frame encoding and P frame encoding are performed, the reference frame of the P frame encoding is the last frame of the previous data frame, a human face in the video data is recognized, a human body frame corresponding to the human face is encoded independently, the human body frame code is stored in a storage, a playback request is responded when received, data frame information of a playback time node is acquired firstly, the I frame and the P frame of the data frame are played back to a client, position information of the human body frame is called from the storage and output to the client, and the position point of the human body frame can be moved in the playing process of the data frame after a touch signal of the client is received. With the adoption of the method, data in an image can be suspended or moved at any time while a video is played back, and real-time online processing of pixels is performed.

Description

Technical field [0001] The present invention relates to the technical field of video processing, in particular to a video playback method. Background technique [0002] In video technology processing, video playback is usually required. In some video playback processes, video data needs to be processed, such as moving something or someone in the video. The traditional video playback technology retrieves the playback time point through the cache, and then replays it, but it cannot pause the playback video and move a certain view of the image. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a video playback method, which adopts a brand-new idea, can pause or move the data in the image at any time when the video is played back, and perform real-time online processing of pixels. [0004] In order to achieve the above objective, the technical solution adopted by the present invention is a video playback method including th...
