| 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; | |
| } | |
| } | |

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. | |
