内存泄露问题

1. 在VIO-->编解码 --》推流过程中。出现了内存泄露导致后面申请不到内存，导致初始化失败

现象:

1.1在做一路,摄像头编解码的过程中，出现了内存泄露问题

1.2解决问题的思路

在相应的位置添加对应的log

在vio init启动的时候，

查看占用了多少内存

在vio delete

查看释放了多少内存

统计得到两者的释放和占用的比列:

vio init...

解决方法:分段解决

1.单独使用VIO进行处理 -------------没有发生内存泄露

2. 和标准的相对，--------------------- 做了初始化，没有做相关的释放工作
