您好！目前我在DM8148中做ipnc的开发，ipnc_rdk是3.5的版本，我想将camera link中的的图像传送到dsp中进行处理，其中数据的流是：camera link–>dup link–>ipcFramesOut link–>ipcFramesIn link–>VA link ,但是我发现数据帧到底dsp后发生了变化，后来跟踪代码发现，从camera link中过来的数据到ipcFramesOut link中都是正确的 ，但是到了ipcFramesIn link 后数据帧就会发生变化，开始我认为可能的原因是ipcFramesOut link中进行了跳帧，可是在不跳帧的情况下，数据帧也不同，而且，很怪异的是，前8帧数据是一样的，之后的数据就会发生变化，我想请问您一下，造成这种现象的可能原因有哪些？希望您能给我点建议！
Haijun Guo：
ipcFramesOut link 和 ipcFramesIn link之间是怎么连接的？ 应当是：ipcFramesOut link 的 processLink 是ipcFramesIn link（DSP）。
前8帧数据一样，这个是正确的吗？我感觉是buffer队列满了之后出现了数据变化。有没有什么地方分配8个buffer的？

感谢Haijun Guo的回复，ipcFramesOut link 与ipcFramesIn link的连接是参考的usescase，应该是没有问题的，代码如下：
/* IPC Frames Out VPSS for VA link params */ ipcFramesOutVpssPrm.baseCreateParams.inQueParams.prevLinkId = dupId[SCALER_DUP_IDX]; ipcFramesOutVpssPrm.baseCreateParams.inQueParams.prevLinkQueId = 0; ipcFramesOutVpssPrm.baseCreateParams.notifyPrevLink = TRUE; ipcFramesOutVpssPrm.baseCreateParams.inputFrameRate = 30; ipcFramesOutVpssPrm.baseCreateParams.outputFrameRate = 30;
ipcFramesOutVpssPrm.baseCreateParams.numOutQue = 1; ipcFramesOutVpssPrm.baseCreateParams.outQueParams[0].nextLink = ipcFramesInDspId; ipcFramesOutVpssPrm.baseCreateParams.notifyNextLink = TRUE;
ipcFramesOutVpssPrm.baseCreateParams.processLink = SYSTEM_LINK_ID_INVALID; ipcFramesOutVpssPrm.baseCreateParams.notifyProcessLink = FALSE; ipcFramesOutVpssPrm.baseCreateParams.noNotifyMode = FALSE;
/* IPC Frames in DSP for VA link params */ ipcFramesInDspPrm.baseCreateParams.inQueParams.prevLinkId = ipcFramesOutVpssId; ipcFramesInDspPrm.baseCreateParams.inQueParams.prevLinkQueId = 0; ipcFramesInDspPrm.baseCreateParams.numOutQue = 1; ipcFramesInDspPrm.baseCreateParams.outQueParams[0].nextLink = gVsysModuleContext.vaId; ipcFramesInDspPrm.baseCreateParams.notifyPrevLink = TRUE; ipcFramesInDspPrm.baseCreateParams.notifyNextLink = TRUE; ipcFramesInDspPrm.baseCreateParams.noNotifyMode = FALSE;

另外，我又将camera link 、ipcframesout link 和ipcframesIn link中的图像数据打印出来，发现了一些现象：所以的打印中camera link与ipcFramesOut link中的数据一致，
但是在ipcFramesIn link中前9帧（0到8帧）数据与前两者一致，之后凡是8的倍数的帧与前两者一致，偶尔也有不是8的倍数的帧与前两者一致，但是不多（对100帧进行分析）。
具体的打印结果我整理后如下：其中每3行为一组数据，分别对应，ipcFramesIn 、Camera与IpcFramesOut，count 后面的值表示是第几帧，紧随其后的[]里的值是打印的帧的首地址之后的第一个字节与第二个字节的值，用来对比在三个link中是否图像发生变化，最后的十六进制数是帧的首地址。
其中我最疑惑的是，对于一帧图像，在camera link 、ipcframesout link以及ipcframesIn link中都是对应一个缓存，但是为什么到了ipcframesIn link后数据就发生了变化，请您帮我分析一下原因

可以检查一下DUP link另外一支数据通路是否有修改buffer内容的操作，因为buffer的指针在DUP的各个出口分支都是一样的。

回复 Haijun Guo:
感谢Haijun Guo的回复，在dup link后分了两路，其中一路是：dup link–>ipcFramesOut link–>ipcFramesIn link–>VA link；另外一路是：dup link–>scaler link–>FD link ；您说有可能是dup link 的另一路修改了buffer的内容，可是在ipcFramesOut link中数据都还是正确的，这个是否能说明另一路并没有对ipcframesIn link造成影响呢？
在我想把到fd link的那条数据流去掉，但是去掉后程序起不来，但是我在usescase中去掉其他的模块却不会出现这种情况，也希望您帮我分析一下原因

回复 pan hu:
建议你在duplink后面直接接一个null link，先不要sclr 以及FD。
或者干脆去掉dup，再测试，用来缩小问题范围
pan hu：
回复 Haijun Guo:
我在改动数据流时，原来就打算去掉fd link那条链，但是去了之后，程序就不能起来，后来我逐步的缩小范围，发现去掉fd link后就会出现程序起不来的现象，我去掉fd link的过程是这样的：将fd link的前驱（scaler link）的outQueParams.nextLink设置为SYSTEM_LINK_ID_INVALID,并将numOutQue 设置为0，然后将于fd link的创建参数去掉，不知这样删除fd link 是不是错误的？如果是错误的我该怎么删掉fd link？希望您指点我一下，谢谢！！
