Abstract: A method including receiving an input media stream and splitting a video portion of a received portion of the input media stream into input video chunks. For each input video chunk of the video portion of the input media stream, the method includes assigning the input video chunk to one or more slave transcoders, splitting the input video chunk into video subchunks, and separately feeding each input video subchunk to each of the one or more slave transcoders. The method includes separately receiving output video subchunks from the one or more slave transcoders. Each output video subchunk respectively corresponds to one of the input video subchunks. The method also includes assembling the output video subchunks into an output video chunk corresponding to the input video chunk and assembling the output video chunks into an output media stream.

Abstract: A method including receiving an input media stream and splitting a video portion of a received portion of the input media stream into input video chunks, while receiving a remaining portion of the input media stream. For each input video chunk of the video portion of the input media stream, the method includes assigning the input video chunk to one or more slave transcoders, splitting the input video chunk into video subchunks, and separately feeding each input video subchunk to each of the one or more slave transcoders. The method includes separately receiving output video subchunks from the one or more slave transcoders. Each output video subchunk respectively corresponds to one of the input video subchunks. The method also includes assembling the output video subchunks into an output video chunk corresponding to the input video chunk and assembling the output video chunks into an output media stream.

Abstract translation: 一种方法，包括在接收输入媒体流的剩余部分的同时接收输入媒体流并将输入媒体流的接收部分的视频部分分割成输入视频块。 对于输入媒体流的视频部分的每个输入视频块，该方法包括将输入视频块分配给一个或多个从属代码转换器，将输入视频块分成视频子块，以及将每个输入视频子块分别馈送到 一个或多个从属代码转换器。 该方法包括从一个或多个从属代码转换器分别接收输出视频子块。 每个输出视频子块分别对应于一个输入视频子块。 该方法还包括将输出视频子块组装成与输入视频块对应的输出视频块，并将输出视频块组装成输出媒体流。
