Embodiment Construction

[0018] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 It is a flowchart of a method for processing jitterbuf memory according to an embodiment of the present invention. Such as figure 1 As shown, the jitterbuf memory processing method includes the following processing:

[0020] Step S101: When the memory pool receives a memory release request, determine whether the number of free memory blocks in the memory pool reaches a preset threshold;

[0021] Step S103: In the case that the number of free memory blocks does not reach the preset threshold, the memory pool reserves the memory blocks requested to be released.

[0022] In related technologies, when a data packet is received, jitterbuf allocates a memory to store the data packet according to the received data packet. When jitterbuf sends the complete frame to decode, the memory of these data packets needs to be destroy...

Abstract

The invention discloses a jitterbuf memory processing method and device. According to the method, when a memory pool receives the request for memory freeing, whether the number of free memory blocks in the memory pool reaches a preset threshold value or not is judged; under the condition that the number of the free memory blocks does not reach the preset threshold value, the memory pool reserves the memory blocks which requests to be freed. According to the technical scheme, the memory blocks do not need to be allocated and destroyed frequently, processing time is saved, and memory fragments can not be generated easily.

Description

technical field [0001] The present invention relates to the communication field, in particular to a jitterbuf memory processing method and device. Background technique [0002] At present, the memory management of the smartphone jitter buffer (jitterbuf) is mainly realized through the following two methods. [0003] One memory management scheme is array-based jitterbuf. The array is simulated as a ring buffer (buffer), and jitterbuf stores the data packets at the corresponding position according to the timestamp (timestamp) and sequence number (sequence). In the array-based jitterbuf, the memory has been allocated at the time of initialization, and the data can be directly stored in the array. The advantage of this approach is that it does not need to allocate and destroy memory frequently, which reduces the CPU burden and will not Generate memory fragmentation. However, this method has the following disadvantages: the memory capacity cannot be expanded, and in order to m...
