如果系统相对复杂，dvrdk自带的模块数量不够，可否扩展，如：
1、DUP_LINK_MAX_OUT_QUE从系统默认的5扩大到8；
2、SYSTEM_VPSS_LINK_ID_DUP_3扩大到SYSTEM_VPSS_LINK_ID_DUP_5
3、SYSTEM_VPSS_LINK_ID_MERGE_4扩大到SYSTEM_VPSS_LINK_ID_MERGE_6
是否可行，简单的修改或添加对应的宏就可以了吗，有哪些需要注意的细节。谢谢！
你好，
请注意Link里面buffer的还回是最后使用的buffer的link用完后，一层一层往上还的。如果DUP等link太多，只要DUP下面的有一个link没有把buffer用完，这个buffer就不能还回，如果还回不及时就可能导致Link里buffer拿不到的情况。
简单的将#define DUP_LINK_MAX_OUT_QUE (5) 改为#define DUP_LINK_MAX_OUT_QUE (18)后
出现如下编译错误：
