摘要： Approaches for dynamically allocating CPU cycles for use in processing a video stream. Video complexity information for two or more digital video streams actively being processed by one or more video encoders is determined at periodic intervals. Video complexity information describes the complexity of digital video carried by the digital video streams across a bounded number of consecutive digital frames which includes digital frames not yet processed by the one or more video encoders. A determination is made as to whether a number of CPU cycles allocated for processing a particular digital video stream should be adjusted based on the determined video complexity information. The number of CPU cycles allocated for processing the particular digital video stream may be dynamically adjusted by changing an amount of CPU cycles allocated to a virtual machine in which the stream is processed or by processing the stream in a different virtual machine.

摘要： A scheduler of video processes to be run on a cluster of physical machines. The scheduler splits video content into a plurality of video sequences based on at least one of a scene cut detection, a minimum duration, or a maximum duration. The video sequences are to be encoded on Operating-System-Level virtual environments in parallel. The scheduler also calculates, for each video sequence, based at least in part on the video sequence and a target coding time of the video content, a target computing capacity of an Operating-System-Level virtual environment to code the video sequence. The scheduler may also create, for each video sequence, an Operating-System-Level virtual environment having the target computing capacity to be instantiated on a physical machine in the cluster of physical machines.

摘要： Scheduling of processes in a cluster of physical machines. Complex processes are split into elementary processes. To run each elementary process, an isolated execution environment is created and allocated on a physical machine. The isolated execution environment is created in order to have a computing capacity at least equal to a computing load of the elementary process.

摘要： The estimation of a computing capacity of a machine. The computing capacity is estimated by iteratively adding and removing calibrated computer processes on the machine, and performing a sum of computing loads of processes that execute on the machine. In order to characterize the ability of a machine to run in parallel a number of processes having a defined computing load, the processes are associated to a condition of success.
