Abstract
A system (and a method) are disclosed for a video processing system cascading multiple transcoders. The system includes a first transcoder, a second transcoder and an optional third transcoder. The first transcoder is a pre-processing transcoder configured to preprocess an input video stream into a first bitstream in a first video format. The second transcoder is a primary transcoder configured to transcode the first bitstream into a second bitstream in a second video format. The third transcoder comprises a post-processing transcoder configured to further transcode the second bitstream into a third bitstream in a third video format. Pre-processing and post-processing the input video stream by the cascaded transcoders allows the system to more efficiently and quickly transcode the input video stream. Pre-processing and post-processing the input video further improves processing efficiency and speed and also increases throughout of coding processing.
