Problems solved by technology

[0004] The disadvantage of the above transcoding method is that because multiple video clips need to be transcoded one by one, when there are many video clips, it will take a lot of time, resulting in inconsistency with the audio playback time, which has a great impact on the user's viewing

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 The flow of the video transcoding method provided by the embodiment of the present invention is shown.

[0022] In step S101, receiving a user's transcoding instruction;

[0023] In step S102, the original video file is decomposed into a plurality of first video slices;

[0024] In step S103, a plurality of first video slices after decomposition are simultaneously transcoded into second video slices;

[0025] Wherein, when performing transcoding, the video slices decomposed from the original video file are transcoded according to the transcoding instruction in step S101.

Abstract

The invention is suitable for the technical field of audio-video playing, and discloses a method and a system for parallel trans-coding of video slicing. The method comprises the following steps of: disassembling an original video file into a plurality of first video segments; simultaneously trans-coding the first video segments after disassembling into second video segments; and assembling a plurality of the second video segments after trans-coding into a video file with a new format. In the method, by disassembling the original video file into the plurality of the first video segments, simultaneously trans-coding the first video segments after disassembling into the second video segments, and assembling the plurality of the second video segments after trans-coding into the video file with the new format, not only the trans-coding time is saved and the trans-coding efficiency is improved, but also the texture of a picture is well ensured, and the method and the system are favorable for popularizing an audio-video playing device.

Description

technical field [0001] The invention belongs to the technical field of audio and video, and in particular relates to a method and system for parallel transcoding of video slices. Background technique [0002] With the rapid development of audio and video playback technologies, users have higher and higher requirements for audio and video playback functions. [0003] When transcoding a video, the traditional method is to slice the original video file into multiple video slices, and then transcode the multiple cut out video slices one by one. For example, for an existing large video, assuming that the video can be divided into 7 segments, and transcoding each segment takes n seconds, the user can watch the transcoded video file after 7n seconds. [0004] The disadvantage of the above transcoding method is that since multiple video clips need to be transcoded one by one, when there are many video clips, it will take a lot of time, resulting in inconsistency with the audio play...
