摘要： A host has a graphics pipeline that process frames by portions (e.g., pixels or rows) or slices. A remote device transmits a video stream container via a network to the host. A frame of the video stream in the container has encoded portions. The graphics pipeline includes a demultiplexer that extracts the portions of the video frame. When a portion has been extracted it is passed to a decoder, which is next in the pipeline. The decoder may begin decoding the portion before receiving a next portion of the frame, possibly while the demultiplexer is demultiplexing the next portion of the frame. A decoded portion of the frame is passed to a renderer which accumulates the portions of the frame and renders the frame. At any time portions of a frame might concurrently be being received, demultiplexed, decoded, and rendered. The decoder may be single-threaded, multi-threaded, or hardware accelerated.
