Abstract: A method, computer program product, and system are provided for multi-threaded video encoding. The method includes the steps of generating a set of motion vectors in a hardware video encoder based on a current frame of a video stream and a reference frame of the video stream, dividing the current frame into a number of slices, encoding each slice of the current frame based on the set of motion vectors, and combining the encoded slices to generate an encoded bitstream.

Abstract translation: 提供了一种用于多线程视频编码的方法，计算机程序产品和系统。 该方法包括以下步骤：基于视频流的当前帧和视频流的参考帧，在硬件视频编码器中生成一组运动矢量，将当前帧划分成多个片段，编码每个片段 基于所述运动矢量集合的当前帧，以及组合所述编码的片以生成编码的比特流。
