Abstract

The embodiment of the present invention discloses a video transcoding method and device. A video transcoding method includes: determining each transcoding device that stores the first video file to be transcoded in the memory, and among the determined transcoding devices Any one of the transcoding devices includes a memory and a processor; obtain the determined processing performance of the processors of each transcoding device; select one of the determined transcoding devices according to the obtained processing performance A transcoding device for performing a transcoding task; controlling the processor in the selected transcoding device to transcode the first video file to be transcoded stored in the memory of the transcoding device, and transcoding the transcoded video file The file is stored in the memory of the transcoding device. Applying the above-mentioned technical solution, when performing video transcoding, it is only necessary to transmit video files between the processor and memory in one transcoding device, avoiding the use of the network to transmit files, saving transcoding time, and improving improved transcoding efficiency.

Description

technical field [0001] The present invention relates to the technical field of video processing, and in particular, to a video transcoding method and device. Background technique [0002] With the rapid development of network multimedia technology, the playback form of video files is no longer limited to a specific video stream. This requires the video service provider to use the transcoding system to transcode the video files, so as to obtain video streams of various resolutions for the video player to play. [0003] In order to improve transcoding efficiency, the transcoding system consists of multiple machines. The machines in the existing transcoding system are divided into two parts, one part is used as a transcoding device, and the other part is used as a storage device. The memory in the machine serving as the storage device stores the video files to be transcoded. In order to prevent data loss due to equipment failure, usually, a video file to be transcoded is back...
