Abstract

The invention discloses a video editing method based on IOS equipment. The ISO equipment is provided with a first buffer area and a second buffer area. The method comprises the steps that after a video editing instruction is received, whether first editing data exist in a memory address corresponding to the address of the first buffer area or not is judged, wherein the video editing instruction comprises the routing information of target rich media data; if yes, the first editing data are acquired and encoded; if no, a first data acquiring request is generated; whether second editing data exist in the second buffer area or not is judged according to the first data acquiring request; if yes, the second editing data are acquired and rendered, and the first editing data are generated and stored in the first buffer area; otherwise, corresponding target rich media data are acquired according to the routing information, the target rich media data are decoded, and the second editing data are acquired and stored in the second buffer area.

Description

technical field [0001] The invention relates to the technical field of video editing, in particular to an IOS device-based video editing device and an IOS device-based video editing method. Background technique [0002] In recent years, with the rapid development of computer graphics and image technology, picture and video editing technology has gradually matured, and has become the main tool for making film and television programs and digital multimedia. Among them, picture and video editing refers to the processing of pictures or videos, such as: combining multiple high-definition videos into a continuous video, cutting a complete video into multiple videos, merging multiple videos into a single video, adding background music, changing the video quality, etc. Color and other operations on the video. [0003] However, in the existing picture and video editing process, if special effects need to be added to the video, it needs to go through multiple encoding and decoding pr...
