A question about DM8148 IPCFRAMES link

Z-SEED

Other Parts Discussed in Thread: TVP7002

Hi,

I used capture/display mode in DM8148, the input was from TVP7002.

When the link is capture ---> display, the video I received is suspended, just a image. I thought maybe it was because I had not enough time to deal the data. Then I changed the link to capture ---> ipcFramesOutVpss ---> display, at the same time there is a processlink in ipcFramesOutVpss: ipcFramesOutVpss ---> ipcFramesIndsp ---> dspAlg. Then I saw the screen black.

Could somebody give me some advices please? Thanks.

My program is:

    gVcapModuleContext.ipcFramesOutVpssId[0] = SYSTEM_VPSS_LINK_ID_IPC_FRAMES_OUT_0;
    gVcapModuleContext.ipcFramesInDspId[0] = SYSTEM_DSP_LINK_ID_IPC_FRAMES_IN_0;
    gVcapModuleContext.dspAlgId[0] = SYSTEM_LINK_ID_ALG_0;
  
    capturePrm.outQueParams[0].nextLink = gVcapModuleContext.ipcFramesOutVpssId[0];
    pCaptureOutPrm->outQueId = 0;
 
    /* Set ipcFramesOutVpss link info */
    ipcFramesOutVpssPrm.baseCreateParams.noNotifyMode = FALSE; 
    ipcFramesOutVpssPrm.baseCreateParams.notifyPrevLink = TRUE;
    ipcFramesOutVpssPrm.baseCreateParams.inQueParams.prevLinkId = gVcapModuleContext.captureId;
    ipcFramesOutVpssPrm.baseCreateParams.inQueParams.prevLinkQueId = 0;
    ipcFramesOutVpssPrm.baseCreateParams.numOutQue = 1;
    ipcFramesOutVpssPrm.baseCreateParams.notifyNextLink = TRUE;
    ipcFramesOutVpssPrm.baseCreateParams.outQueParams[0].nextLink = gVdisModuleContext.displayId[0];
    ipcFramesOutVpssPrm.baseCreateParams.notifyProcessLink = TRUE;
    ipcFramesOutVpssPrm.baseCreateParams.processLink = gVcapModuleContext.ipcFramesInDspId;
  
    //prevLink->processLink->nextLink
    ipcFramesInDspPrm.baseCreateParams.noNotifyMode = FALSE;
    ipcFramesInDspPrm.baseCreateParams.notifyPrevLink = TRUE;
    ipcFramesInDspPrm.baseCreateParams.inQueParams.prevLinkId = gVcapModuleContext.ipcFramesOutVpssId[0];
    ipcFramesInDspPrm.baseCreateParams.inQueParams.prevLinkQueId = 0;
    ipcFramesInDspPrm.baseCreateParams.numOutQue = 1;
    ipcFramesInDspPrm.baseCreateParams.notifyNextLink = TRUE;
    ipcFramesInDspPrm.baseCreateParams.outQueParams[0].nextLink = gVcapModuleContext.dspAlgId[0];
 
    dspAlgPrm.enableOSDAlg = TRUE;
    dspAlgPrm.enableSCDAlg = FALSE;
    dspAlgPrm.inQueParams.prevLinkId = gVcapModuleContext.ipcFramesInDspId[0];
    dspAlgPrm.inQueParams.prevLinkQueId = 0;
    dspAlgPrm.outQueParams.nextLink = SYSTEM_LINK_ID_INVALID;

    /* display link params */
    MULTICH_INIT_STRUCT(DisplayLink_CreateParams,displayPrm);
    displayPrm.inQueParams[0].prevLinkId = gVcapModuleContext.ipcFramesOutVpssId[0];
    displayPrm.inQueParams[0].prevLinkQueId = 0;
    displayPrm.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_HDMI].resolution;
    displayPrm.displayId  = DISPLAY_LINK_DISPLAY_SC1;

    /* Links Creation */
    System_linkCreate(gVcapModuleContext.captureId, &capturePrm, sizeof(capturePrm));
    System_linkControl(gVcapModuleContext.captureId, CAPTURE_LINK_CMD_DETECT_VIDEO, NULL, 0, TRUE);

    /* IpcFrames link */
    System_linkCreate(gVcapModuleContext.ipcFramesOutVpssId[0], &ipcFramesOutVpssPrm, sizeof(ipcFramesOutVpssPrm));
    System_linkCreate(gVcapModuleContext.ipcFramesInDspId[0], &ipcFramesInDspPrm, sizeof(ipcFramesInDspPrm));
    System_linkCreate(gVcapModuleContext.dspAlgId[0], &dspAlgPrm, sizeof(dspAlgPrm));

    /* display link */
    System_linkCreate(gVdisModuleContext.displayId[0], &displayPrm, sizeof(displayPrm));

    Hi,
    I used IPNC RDK v3.8. And I changed camera to capture in multich_capturedisplay.c, and I was successful in HDMI IN and HDMI OUT mode using the link from capture to display. Now I want to use tvp7002 instead SII9125.

    Hi,

    The capture->display is the simple use case which you should get working.

    Pl. check if the capture is happening properly by putting debug messages in the capture link call back.

    regards,

    Anand

    Hi,
    How should I do to check this? Thanks.

    Hi,

    There is callback function 'CaptureLink_drvCallback()' defined in the '..\ipnc_rdk\ipnc_mcfw\mcfw\src_bios6\links_m3vpss\capture\captureLink_drv.c' file which is called from the capture driver after a frame is captured.
    You can put debug messages here like 'Vps_rprintf("Frame Received\n");'.

    regards,
    Anand

    Hi,
    I found an error in the printf log: Assertion @ Line: 560 in links_m3vpss/display/displayLink_drv.c: status == 0 : failed !!!
    The error occured when Utils_queGet runned which is in the function DisplayLink_drvSetFrameInfo. What will call the display queget error? Thanks.

    Part of my log is :

    Hi,

    The 'Utils_quePut()' for the frameInfo queue is done in DisplayLink_drvDeQueue() fn so pl. check if this function is getting called.

    regards,

    Anand

    When I add printf in DisplayLink_drvDeQueue(), the error disappeared, and the log shows Utils_quePut() was called. However, the result is the same. "CaptureLink_drvCallback Frame Received." is always be printfed, I guess the capture input is OK. But functions with the prefix "DisplayLink_drv" were disappered. Does this mean that the HDMI display is wrong?

    Hi,
    May I ask if TVP7002 support RGB888 output mode? Thanks. I used TVP7002 as: input YPbPr 720p60, output RGB888 720p60. Should I?
