PARALLEL VIDEO TRANSCODING

摘要

A system and method provides transcoding a video in parallel by multiple transcoders based on a measure of video coding complexity (VCC). The system has a video pre-processing module, a master transcoder, a transcoding controller and multiple transcoders. The video pre-processing module transcodes a source video into an intermediate video. The master transcoder partitions the intermediate video into multiple transcoding units, where a transcoding unit identifies a portion of data of the intermediate video for transcoding. The master transcoder further generates a transcoding request for each transcoding unit. The transcoding controller distributes the transcoding units to the multiple transcoders, which transcode the data of the transcoding units in parallel into transcoded data

1. A system for transcoding a source video in parallel, the system comprising:
a non-transitory computer-readable medium storing executable computer modules; and a processor configured to execute a master transcoder and a plurality of transcoders stored in the computer-readable medium, wherein
the master transcoder partitions an intermediate video generated from the source video into a plurality of transcoding units, a transcoding unit identifying a portion of data of the intermediate video for transcoding and having one or more transcoding parameters,the plurality of transcoders transcode the data of the plurality of transcoding units in parallel into transcoded data, the transcoded data having a second video format, andthe master transcoder further merges the transcoded data of the plurality of transcoding units into a merged video stream.
