Ticket Name: TDA2HF: Set DSS parameter failed when Display_Link was creating
Query Text:
Part Number: TDA2HF In PROCESSOR_SDK_VISION_03_08_00_00,i builded a chain: capture->vpe->display vpe params was set as below:
static Void chains_vipSingleCam_Enc_Dec_SgxDisplay_SetVPEPrms(
VpeLink_CreateParams *pPrm,
UInt32 numLvdsCh,
UInt32 displayWidth,
UInt32 displayHeight,
UInt32 inputWidth,
UInt32 inputHeight
)
{
UInt16 chId;
pPrm->enableOut[0] = TRUE;
for(chId = 0; chId < numLvdsCh; chId++)
{
pPrm->chParams[chId].outParams[0].numBufsPerCh =
VPE_LINK_NUM_BUFS_PER_CH_DEFAULT;
pPrm->chParams[chId].outParams[0].width = displayWidth;
pPrm->chParams[chId].outParams[0].height = displayHeight;
pPrm->chParams[chId].outParams[0].dataFormat =SYSTEM_DF_RGB24_888 ;
pPrm->chParams[chId].scCfg.bypass = FALSE;
pPrm->chParams[chId].scCfg.nonLinear = FALSE;
pPrm->chParams[chId].scCfg.stripSize = 0;
pPrm->chParams[chId].scCropCfg.cropStartX = 32;
pPrm->chParams[chId].scCropCfg.cropStartY = 24;
pPrm->chParams[chId].scCropCfg.cropWidth = inputWidth-32;
pPrm->chParams[chId].scCropCfg.cropHeight = inputHeight-24;
}
}
then i got assert as below: [HOST] [IPU1-0] 57.923595 s: CaptureLink_drvAllocAndQueueFrames:1553:FVID2_queue: captureVipHandle=0x9f11b880, frameList.numFrames=6, streamId=0

[HOST] [IPU1-0] 58.166748 s: Assertion @ Line: 474 in displayLink_drv.c: status==SYSTEM_LINK_STATUS_SOK : failed !!! But when i use capture->vpe->sgxFmcpy(A15)->display,display_link can run normal in SYSTEM_DF_BGRA16_4444 . I want to know why dispaly_link cant be creanted in SYSTEM_DF_RGB24_888,or how to make display_link run in SYSTEM_DF_RGB24_888 .
Responses:
Hi, I think DSS does not support RGB24_888 format, ie R in lower byte, followed by G, followed by B. DSS supports BGR24_888 format, So can you try changing it to system_df_BGR24_888 format? Regards, Brijesh
Thanks for your reply. Dont know why ,but display does run normal with BGR24_888,
Because it is only supported in the DSS. The other RGB packed format is not supported.
