[討論]讀取影像資料



Dear all:

後學想要將影像資料抓來看,先確定抓到影像資料的位置,然後判斷座標的顏色

,想請問 我在 Func: Int32 Capturelink_drvProcessData (capturelink_Obj *pobj)

中的for 迴圈 

for(streamID = 0; streamId< CAPTURE_LINK_MAX_OUTPUT_PER_INST; streamId++)

{

........

         FVID2_dequeue(pObj->fvidHandleVipAll,&framelist,streamId,BIOS_NO_WAIT);

.......

}

printf("%d  read pixal data\n!!!", pFrame->addr[0][0]);

然後重新 compiler, 燒錄NAND Flash ,我在log 並看不到 有輸出影像資料的數值,請問是哪裡有問題嗎,感謝各位提示

謝謝
