摘要： Systems and methods of transcoding video sequences for delivery in a mobile network. A source video sequence including source video frames is received and a source video frame type associated with each of the source video frames is determined based on a differential between a composition time stamp (CTS) and a decoding time stamp (DTS) associated with each of the source video frames. A frame type ratio value for the target frame-types is calculated based on a longest mini-GOP length. A target frame size of each target video frame is determined based on the frame type ratio value and a target transcoding rate, and each of the target video frames in a target video track is encoded to the target frame size to form a target video sequence.

摘要： Systems and methods are described herein for adaptively transcoding media in a communications network such that computer processing resources are effectively utilized to deal with varying traffic patterns in the communications network. A computing device receives a request to transcode content and determines a first amount of tokens based on a number of CPU cores associated with the computing device, and a currently used amount of tokens. The computing device determines a second amount of tokens associated with transcoding the content and when the first amount of tokens is less than the second amount of tokens, the computing device bypasses transcoding for the content or adjusts a transcoding parameter to reduce a number of tokens associated with transcoding the content.
摘要翻译：这里描述了用于在通信网络中自适应地转码媒体的系统和方法，使得计算机处理资源被有效地用于处理通信网络中的变化的业务模式。计算设备接收对内容进行代码转换的请求并且基于与计算设备相关联的CPU核心的数量以及当前使用的令牌量来确定令牌的第一数量。计算设备确定与对内容进行代码转换相关联的令牌的第二数量，并且当第一数量的令牌小于第二数量的令牌时，计算设备绕过内容的代码转换或者调整代码转换参数以减少与代码相关联的令牌的数量并对内容进行转码。
