Problems solved by technology

[0004] In the process of realizing the present invention, the inventor finds that the above-mentioned technology has at least the following problems: since the process of using FFmpeg to perform video compression is transplanted from the video compression process of the desktop PC, but due to the performance of the mobile terminal when running FFmpeg It is not yet comparable to the performance of a desktop PC, so the processing speed of the current video compression method is relatively slow

Abstract

The application discloses a video compression method, device and electronic equipment, and belongs to the multimedia processing field; the method comprises the following steps: obtaining at least one frame of video data and video parameters of the video data; modifying the video parameters of the video data into compressed video parameters; compressing the at least one frame of video data through a hardware acceleration function of a mobile terminal according to the compressed video parameters, thus obtaining a compressed video file. The method and device solves the problems that a conventional video compress method is slow in processing speed, and the hardware acceleration function of the mobile terminal can compress the video, thus improving video compression method processing speed effect on the mobile terminal.

Description

technical field [0001] The embodiments of the present invention relate to the field of multimedia processing, in particular to a video compression method, device and electronic equipment. Background technique [0002] With the development of mobile devices such as smartphones, tablet computers and e-readers, the use of multimedia data on mobile terminals is becoming more and more widespread. [0003] Since the network environment where the mobile terminal is located is variable and complex, the available bandwidth is easily limited. Therefore, when the mobile terminal needs to upload a video file with a large amount of data to the network side, it usually needs to compress the video file. A current video compression method includes: the mobile terminal uses an open source video processing library FFmpeg to recompress and encode the video data in the video file to obtain a recompressed and encoded video file with a smaller amount of data. [0004] In the process of realizing...
