摘要： The present disclosure discloses a video encoder, a video encoding system and a video encoding method. The video encoder comprises a logic control module and an encoding module. Wherein, the logic control module is configured to receive a control command sent from an external controller for encoding a specified portion of each frame of image, and send the control command to the encoding module; and the encoding module is configured to receive the control command from the logic control module, and encode the specified portion of each frame of image according to the control command, so as to cooperate with a plurality of other video encoders to complete encoding each frame of image. By employing the video encoder, video encoding system and video encoding method according to the present disclosure, each frame of image can be accomplished jointly by a plurality of video encoders, thus significantly reducing the encoding time, diminishing the encoding latency, and achieving real-time encoding of high-definition video sources, in particular, video sources with a resolution ratio of 4 k or above.

摘要： Disclosed are systems and techniques for efficient real-time codec encoding of video files. In one embodiment, the techniques include obtaining a first plurality of motion vectors of a first resolution, generating a second plurality of motion vectors of a second resolution, and calculating a first cost of the motion vector using a first cost function of a first size. The techniques include selecting a subset of motion vectors of the second plurality of motion vectors, calculating a second cost using a second cost function of a second size, and generating a plurality of combined motion vectors based on the subset of motion vectors. The techniques include calculating a third cost using the second cost function of the second size, selecting a final motion vector, and generating, based on the selected final motion vector, a block of predicted pixels that approximates a block of source pixels of an image frame.
