Virtual memory pool design method based on Darwin streaming media server

Abstract

The invention discloses a virtual memory pool design method based on a Darwin streaming media server. The virtual memory pool design method based on the Darwin streaming media server comprises the steps of: S100, designing a virtual memory module plug-in framework based on the original plug-in design method of the Darwin streaming media server; additively creating a virtual memory role, and setting a virtual memory protection attribute role; S200, designing functional functions corresponding to a newly increased plug-in role, wherein the functional functions comprise virtual memory designing and creating function, an available virtual memory block obtaining functional function, a virtual memory block resetting functional function and a virtual memory pool protection attribute functional function; and S300, designing a role in a shared virtual memory pool plug-in to an application interface according to the plug-in rule of the Darwin streaming media server. By means of the method in theinvention, the problem that the original Darwin streaming media server only can use and manage a small data object in a heap memory manner and cannot use and manage a large data object can be solved.

Description

technical field [0001] The invention relates to a design method of a virtual memory pool based on a Darwin streaming media server. Background technique [0002] 1. The existing Darwin streaming server data system and memory components all use heap memory, and heap memory is suitable for managing a large number of small data objects. [0003] 2. On the commercial Darwin streaming server, because the original Darwin streaming server does not provide the function of converting code streams, it cannot be used by different types of clients. Therefore, the function of converting code streams is added to the secondary development of the original Darwin streaming media server Sometimes, the original heap memory usage method cannot meet the memory usage of large data objects during the code stream conversion process. [0004] 3. On large-scale commercial servers, the use of heap memory will generate a large amount of memory fragmentation and unpredictable paging in the system, which...
