8168下利用ipcframe运行DSP端算法时,显示黑屏,求解

一个简单的demo,代码如下:

CaptureLink_CreateParams capturePrm;
CaptureLink_VipInstParams *pCaptureInstPrm;
CaptureLink_OutParams *pCaptureOutPrm;
HelloWorldLink_CreateParams helloWorldPrm;

ipcFramesOutVpssPrm.baseCreateParams.inQueParams.prevLinkQueId = 0;
ipcFramesOutVpssPrm.baseCreateParams.notifyPrevLink = FALSE;

ipcFramesOutVpssPrm.baseCreateParams.numOutQue = 1;
ipcFramesOutVpssPrm.baseCreateParams.outQueParams[0].nextLink = displayId;
ipcFramesOutVpssPrm.baseCreateParams.notifyNextLink = TRUE;

ipcFramesOutVpssPrm.baseCreateParams.processLink = ipcFramesInDspId; //dy-omit
ipcFramesOutVpssPrm.baseCreateParams.notifyProcessLink = TRUE;
ipcFramesOutVpssPrm.baseCreateParams.noNotifyMode = FALSE;

ipcFramesInDspPrm.baseCreateParams.inQueParams.prevLinkId = ipcFramesOutVpssId;

Chains_displayCtrlInit(chainsCfg->displayRes);

System_linkCreate(ipcFramesOutVpssId, &ipcFramesOutVpssPrm, sizeof(ipcFramesOutVpssPrm)); //dy-omit
System_linkCreate(ipcFramesInDspId, &ipcFramesInDspPrm, sizeof(ipcFramesInDspPrm));//dy-omit
System_linkCreate(helloWorldId, &helloWorldPrm, sizeof(helloWorldPrm));//dy-omit
System_linkCreate(displayId, &displayPrm, sizeof(displayPrm));

Chains_memPrintHeapStatus();

{
System_linkStart(displayId);
System_linkStart(ipcFramesOutVpssId);//dy-omit
System_linkStart(ipcFramesInDspId);//dy-omit
System_linkStart(helloWorldId);//dy-omit
System_linkStart(captureId);
printf("\n\n1015a-cap ipcout ipcin dis\n\n");

while(1)
{
ch = Chains_menuRunTime();
if(ch=='0')
break;
if(ch=='v')
System_linkControl(captureId, CAPTURE_LINK_CMD_FORCE_RESET, NULL, 0, TRUE);
if(ch=='p') {
System_linkControl(captureId, CAPTURE_LINK_CMD_PRINT_ADV_STATISTICS, NULL, 0, TRUE);
System_linkControl(helloWorldId, HELLOWORLD_LINK_CMD_PRINT_STATISTICS, NULL, 0, TRUE);//dy-omit
System_linkControl(displayId, DISPLAY_LINK_CMD_PRINT_STATISTICS, NULL, 0, TRUE);
}
}

System_linkStop(captureId);
System_linkStop(ipcFramesOutVpssId);//dy-omit
System_linkStop(ipcFramesInDspId);//dy-omit
System_linkStop(helloWorldId);//dy-omit
System_linkStop(displayId);
}

System_linkDelete(captureId);
System_linkDelete(ipcFramesOutVpssId);//dy-omit
System_linkDelete(ipcFramesInDspId);//dy-omit
System_linkDelete(helloWorldId);//dy-omit
System_linkDelete(displayId);

Chains_displayCtrlDeInit();

我若将上述代码修改为capture link与display link 直连时图像输出正常。若维持原架构,

即cap——ipcout——ipcin——hello(dsp)

                display

则 显示黑屏。

观察[m3vpss ] 1167561: CAPTURE: Fields = 11 (fps = 0, CPU Load = 0),似乎是没有输入?

希望 得到帮助 ,谢谢

devin dai:

会不会是下面这个linkstart顺序不对?与linkstop的顺序不太匹配。

System_linkStart(displayId);System_linkStart(ipcFramesOutVpssId);//dy-omitSystem_linkStart(ipcFramesInDspId);//dy-omitSystem_linkStart(helloWorldId);//dy-omitSystem_linkStart(captureId);

System_linkStop(captureId);System_linkStop(ipcFramesOutVpssId);//dy-omitSystem_linkStop(ipcFramesInDspId);//dy-omitSystem_linkStop(helloWorldId);//dy-omitSystem_linkStop(displayId);

。。。。。。。。。。。。。

昨晚上不是给你回答了吗?你的chain有问题。仔细看看给你回的邮件。

devin dai:

回复 Robin Edson:

我好像没有收到你的邮件,你发我另一个邮箱吧:334512663@qq.com

万分感谢

Robin Edson:

回复 devin dai:

汗,你再检查下,我昨天晚上回的你邮件。在公司用不了163.

devin dai:

回复 Robin Edson:

你发的是devin_dai@live.com这个邮箱么,这个邮箱的确没收到。

能不能先简单说下chain哪里有问题?晚上再发邮件给我,谢谢了

Robin Edson:

回复 devin dai:

额,好吧,俺搞错了,刚刚用手机看了下,是一个叫张斌的。

wei oozi:

回复 Robin Edson:

能不能说下他的chain问题出在哪?

wei oozi:

回复 wei oozi:

问下你的dsp算法在这个程序里是那个link在运行dsp算法?

wei oozi:

你的程序那一块在做dsp算法处理呢?这个dsp算法是自己写的吗?能告诉我在哪修改的吗?

devin dai:

问题已解决,我只更新了开发板上的XXX.out二进制可执行文件,未更新开发板端的dsp-firmware(XXX.xe674),故导致DSP算法无法执行,造成输出黑屏。
