MY main task is to get the data of Y U V separably and deal with them by my own algorithm！
Right now:
i know the data format is SWOSD_FORMAT_YUV422i as it had been set ( pSwOsdObj->videoWindowPrm.format = SWOSD_FORMAT_YUV422i;) in the function of AlgLink_OsdalgCreate().
i got thr the codes and knew that pInA (pInA = swOsdCtrl->videoWindowAddr ) had been set to the address of video in the function of SWOSD_TI_algRun(). And i tried :
for(i=0;i<1080;i++)
{
for(j=0;j<1920*2;j++)
{
if(j%2!=0)
*(pInA+j)=0x80;
else
}
}
there was something wrong , could you tell how to get the data of Y U V separably ?
