Distributed video transcoding method and device

Abstract

The invention discloses a distributed video transcoding method. The distributed video transcoding method comprises the following steps: a main server segments a video file uploaded by a user to form video segments; a distributed storage device receives the video segments sent by the main server and analyzes the video segments to obtain key / value pairs; a corresponding number of key / value pairs, corresponding to a transcoding task quantity, are acquired from a server according to the transcoding task quantity; the video segments in the distributed storage device are downloaded according to the key / value pairs; the downloaded video segments are transcoded; the distributed storage device receives the video segments after being transcoded from the server and then analyzes the transcoded video segments to obtain transcoded key / value pairs; the main server downloads transcoded video segments from the distributed storage device according to the transcoded key / value pairs and then combines the downloaded video segments. Based on the distributed video transcoding method, the video transcoding time is effectively reduced, and the transcoding efficiency is improved. The invention also discloses a distributed video transcoding device.

Description

technical field [0001] The present invention relates to the technical field of video transcoding, and more specifically, to a distributed video transcoding method and a distributed video transcoding device. Background technique [0002] With the continuous development of mobile phone cameras and the Internet, video sharing has become very common. Since uploaded videos usually have different formats and resolutions, the server that plays the video needs to transcode the video, that is, convert the video from one format to another. Various formats, such as: MP4 format into flv format. The traditional transcoding server is a stand-alone transcoding server, which has restrictions on the size of the video and the number of files uploaded at the same time. For a large number of uploaded videos, it cannot be processed in time, and the transcoding time is long, and even the server stops working due to the heavy load. Or use multiple slave servers associated with the master server t...

The traditional transcoding server is a stand-alone transcoding server, which has restrictions on the size of the video and the number of files uploaded at the same time. For a large number of uploaded videos, it cannot be processed in time, and the transcoding time is long, and the server may even stop working due to heavy load.

Or use multiple slave servers associated with the master server to handle the tasks assigned by the master server. When multiple servers are used for transcoding, each video file will only be assigned to one of the servers for transcoding. When a single video file is too large, there is still the problem that the transcoding time is too long. At the same time, the configuration of the slave server is not considered when transcoding by fragments, which will cause the sub-task processing time of the slave server to be different, and finally reduce the efficiency of the entire task.
