Abstract: Approaches for dynamically allocating CPU cycle resources to a video encoder. A resource allocator assesses an amount of available CPU cycle resources on the hardware device on which it executes. The resource allocator determines that a change in the amount of available CPU cycle resources has occurred. The resource allocator, adjusts, in real-time, which particular cycle profile, in a plurality of cycle profiles, is assigned to at least one of a plurality of video modules. The plurality of cycle profiles each allocate, to video modules, a particular amount CPU cycle resources for processing digital video. The plurality of cycle profiles also each specify a set of configuration settings and are arranged in a sequence based upon the video quality and density achievable by video modules using configuration settings associated with each cycle profile when processing digital video.

动态分配CPU周期资源给视频编码器的方法。 资源分配器评估其执行的硬件设备上的可用CPU周期资源量。 资源分配器确定已发生可用CPU周期资源量的更改。 资源分配器实时调整多个周期配置文件中的哪个特定周期配置文件被分配给多个视频模块中的至少一个。 多个周期配置文件每个向视频模块分配用于处理数字视频的特定量的CPU周期资源。 多个周期简档还分别指定一组配置设置，并且基于视频模块在处理数字视频时使用与每个周期简档相关联的配置设置可实现的视频质量和密度的顺序排列。
