摘要： A system and method provide a video coding system for optimizing encoding bitrate, distortion and complexity for a video hosting service. The system comprises an encoding module configured to encode multiple videos with a bitrate control strategy, a pair of complexity allocation control parameters and one or more target output video formats specifications, which include target resolution, target bitrate and target quality information. The encoding module obtains encoding bitrate, distortion and complexity performance samples from the encoding. From the encoding bitrate, distortion and complexity performance samples, the encoding module is configured to select optimal encoding bitrate, distortion and complexity performance samples. The encoding computation profile mapping module is configured to obtain multiple computation levels from the optimal encoding bitrate, distortion and complexity performance samples. For each computational level, a pair of optimized complexity allocation control parameters and number of encoding passes are selected.

摘要： Embodiments of the present invention provide a multi-level bidirectional motion estimation method and device. The method includes: searching for matched blocks in a current frame and a previous frame respectively by using M1×M1 blocks of a to-be-interpolated frame as a mirror center, where a algorithm for the search includes a three-dimensional recursive search algorithm or a hexagon search algorithm; determining a first to-be-determined matched block pair, where the first to-be-determined matched block pair is a pair of matched blocks with a minimum sum of binary absolute difference SBAD value among all pairs of matched blocks searched out in the current frame and the previous frame; and if it is determined that the SBAD value of the first to-be-determined matched block pair is greater than or equal to an SBAD threshold, splitting the M1×M1 blocks of the to-be-interpolated frame into M2×M2 blocks, and searching for matched blocks again in the current frame and the previous frame respectively by using the M2×M2 blocks of the to-be-interpolated frame as a mirror center, where an SBAD threshold for searching for the matched blocks again is 1/4 of the SBAD threshold applied in the previous time of searching for the matched blocks. Therefore, accuracy of motion estimation can be improved effectively, and image quality can be improved.
