Problems solved by technology

[0004] In the two-way video processing scheme, hardware decoding of each frame of the two-way video needs to be synchronized, and it is difficult to achieve synchronization. For example, it needs to wait for a certain period of time to achieve synchronization, and the A Images and RGB images need to be copied from the GPU to the CPU for synthesis, which requires CPU overhead for image synthesis; in addition, the live broadcast application itself needs hardware decoding of one video live stream, and additionally requires hardware decoding of these two channels of video. There will be compatibility issues on the model, so the efficiency of terminal processing is very low

Abstract

The embodiment of the present invention discloses an image processing method, device, and storage medium, wherein the method includes: acquiring a video file of a single video stream, each frame of image in the video file is a color image and the grayscale corresponding to the color image The images are spliced ​​together; each frame image in the video file is decoded to generate a data image corresponding to each frame image; the data image is cut to generate a color image and a grayscale image corresponding to each frame image; the color image is Synthesize with the grayscale image to generate a composite image corresponding to each frame of image; generate a target video file according to the composite image, and display the target video file. It only needs to process the video file of a single video stream, avoiding the synchronous hardware decoding of the two-channel video and copying the image from the GPU to the CPU for synthesis, which improves the efficiency of the terminal image processing.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an image processing method, device and storage medium. Background technique [0002] With the continuous popularization of terminals and the rapid development of terminal technology, the applications provided by terminals are becoming more and more abundant. For example, live broadcast applications, users can interact with anchors face-to-face and instantly by opening live broadcast applications on terminals, and watch the anchors broadcast exciting programs in real time. Users can also give gifts to anchors according to their own preferences, and special effects of gifts will be displayed on the terminal. [0003] In the prior art, taking presenting gift special effects as an example, since gift special effects generally require a transparent channel, it is necessary to adopt a two-channel video solution, that is, one channel is used to transmit color images (als...
