Abstract

The invention provides a video special effects rendering method, device and terminal. The video special effects rendering method comprises the following steps: decoding a obtained video source in response to a user instruction to obtain a first video frame data in a particular format; sending the first video frame data and the preset special effects parameters to the GPU, so that the GPU completes the rendering of the first video frame data; and obtaining a second video frame data from the GPU and encoding to obtain a target special effects video, wherein the second video frame data is obtained by rendering the first video frame data by the GPU. According to the video special effects rendering method, the processing ability of the GPU for graphics is effectively utilized, the parallel computing capabilities of the GPU is utilized to speed up the rendering of video effects, and the duration of video rendering is shortened, so that the preview of the video rendering frames is high, the playback of the frames is smooth, and the occupancy rate of the CPU when rendering is reduced, therefore, the heating temperature of the mobile terminal is reduced.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video special effect rendering method, device and terminal. Background technique [0002] In this era of micro-shooting, people hope to use software with video editing functions in mobile terminals such as mobile phones and tablet computers to convert the scattered photos and images of themselves and their family and friends into interesting dynamic videos and share them with family and friends. In this conversion process, rendering video frames is an important link. [0003] Traditional mobile video editing software uses certain special effect algorithms to perform special effect processing on video image data in the CPU through traversal calculations. The CPU has limited computing units and its parallel computing function is not very powerful, which takes up a lot of computing time and computing power. Memory, using the CPU to render video effects is inefficient and t...
