Problems solved by technology

[0003] Most of the existing video production software uses software encoding and decoding methods to encode and decode videos through the CPU. This method leads to high CPU usage, low encoding efficiency, and slow processing speed.
In addition, software that supports hardware encoding and decoding needs to complete video encoding and decoding through dedicated devices (subcards), such as VCD / DVD decompression cards, video compression cards, etc. Most of these special devices are expensive and do not support imperative Manipulation and off-screen rendering

Abstract

The invention belongs to the technical field of video production, and particularly relates to a video producing method, device and system. The video producing method comprises the following steps: reading a configuration file, and acquiring and loading resources for producing a video; starting a rendering engine, and initializing a hardware encoding-decoding environment and an OpenGL off-screen rendering environment; and performing frame-by-frame off-screen rendering to generate raw video streams. Through adoption of an off-screen rendering technology, video production can be run in the form of a background task without being limited by the screen resolution. Through frame-by-frame rendering based on decoding time, audio-video synchronization and animation smoothness of an output video are ensured. Moreover, hardware decoding is performed on videos supporting hardware decoding, and hardware screen capture is performed on content which is already rendered in an off-screen way, so that hardware resources are utilized fully; the CPU (Central Processing Unit) occupation rate in a video producing process is lowered; and the processing efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of video production, and in particular relates to a video production method, device and system. Background technique [0002] Video production is the process of re-editing, integrating, and arranging pictures, videos, and background music to generate a new video file. It is not only the synthesis of original materials, but also the reprocessing of original materials. At this stage, video production technology has been widely used. Whether in life or on the Internet, you can often see various exquisite videos made from photos and videos. Video production software is also emerging in an endless stream. In addition to video production software that can be used on computers, video production software that can be used on mobile terminals is also available. On the other hand, in addition to using the hardware resources of the machine for video production on the computer and mobile terminals, video production is p...
