Hi, erveryone
I try to display the logo(using the static array that present in IPNC application) in video, but it can't work.
My codes are:
1. Init:
if(SWOSD_init()!=0) /* Run SW OSD*/
{
printf(" SWOSD: SWOSD_init Failure................. \n");
return FAIL;
}
iconBuff160_Y = (char *)OSD_CMEM_ALLOC((SWOSD_CHARWIDTHTILOGO_160_64*SWOSD_CHARHEIGHTTILOGO_160_64), 32) ;
iconBuff160_UV = (char *)OSD_CMEM_ALLOC(((SWOSD_CHARWIDTHTILOGO_160_64*SWOSD_CHARHEIGHTTILOGO_160_64)/2), 32);
swosdSetLogoPrm();
for(i=0; i<2; i++)
{
if(SWOSD_createHandle(&osdHndl, &idxHndl[i]) != GS_SUCCESS)
{
printf("Handle Creation Failed in SWOSD(%d).............", i);
return FAIL;
}
else
{
//Setting for 32 BMP windows currently
if(SWOSD_setNumWindows(osdHndl, SWOSD_WINMAX)!=0) /* Run SW OSD*/
{
printf(" SWOSD: SWOSD_setNumWindows Failure................. \n");
return FAIL;
}
swosdSetWinParam(height, width);
//swosdMakeFixWinString(i);
}
algSwosdHndl[i] = osdHndl;
}
static inline void swosdSetLogoPrm(void)
{
OSD_MEMCPY(iconBuff160_Y, TILogo_Y_160_64, SWOSD_CHARWIDTHTILOGO_160_64*SWOSD_CHARHEIGHTTILOGO_160_64);
OSD_MEMCPY(iconBuff160_UV, TILogo_UV_160_64, (SWOSD_CHARWIDTHTILOGO_160_64*SWOSD_CHARHEIGHTTILOGO_160_64)/2);
}
static int swosdSetWinParam(int height, int width)
{
SWOSD_BmpWinPrm bmpWinPrm;
int i = 0;
#ifdef SWOSD_USER_TRANSPARANCY_ON
bmpWinPrm.userTransparancy = SWOSD_RBOOLTRUE;
#else
bmpWinPrm.userTransparancy = SWOSD_RBOOLFALSE;
#endif
//for window 1
bmpWinPrm.enable = SWOSD_RBOOLFALSE;
bmpWinPrm.format = SWOSD_FORMATYUV420p;
bmpWinPrm.startX = 0;
bmpWinPrm.startY = 0;
bmpWinPrm.width = SWOSD_CHARWIDTHTILOGO_160_64;
bmpWinPrm.height = SWOSD_CHARHEIGHTTILOGO_160_64;
bmpWinPrm.lineOffset = SWOSD_CHARWIDTHTILOGO_160_64;
bmpWinPrm.transperencyVal = SWOSD_OSDWHITETRANSVAL;
bmpWinPrm.transperencyRange = SWOSD_OSDWHITETRANSRANGE;
bmpWinPrm.transperencyEnable = SWOSD_BMPTRANSDISABLE;
bmpWinPrm.resizeEnable = 0;
bmpWinPrm.bmpWinAddr = iconBuff160_Y;
bmpWinPrm.bmpWinAddrUV = iconBuff160_UV;
if(SWOSD_setBmpWinPrm(osdHndl, SWOSD_WINDOW_ONE, &bmpWinPrm)!=0)
{
printf(" SWOSD: SWOSD_setBmpWinPrm Failure................. \n");
return FAIL;
}
return SUCCESS;
}
2. Then call this function VIDEO_swosdTskRun() in the while loop of CAPTURE_ThrFxn（）:
int VIDEO_swosdTskRun(int streamId,int width, int height, int frameRate,void *pBufInfo)
{
int startX = 0;
int startY = 0;
SWOSD_MainWinPrm mainWinPrm;
static int osd_count[AVSERVER_MAX_STREAMS] = {0, 0, 0, 0};
//if(gAVSERVER_config.captureConfig[streamId].swosdConfig.swosdEnable)
{
osdHndl = (SWOSD_Hndl *)algSwosdHndl[streamId];
mainWinPrm.format = SWOSD_FORMATYUV420p;
mainWinPrm.lineOffset = width;
mainWinPrm.width = width;
mainWinPrm.height = height - OSA_floor(startY, 2 )/2;
/*OSD does not take care of Vertical offset, therefore care is needed to read UV data*/
if(SWOSD_setMainWinPrm(osdHndl, &mainWinPrm)!=0)
{
printf(" SWOSD: SWOSD_setMainWinPrm Failure................. \n");
return FAIL;
}
if(osd_count[streamId]>=(frameRate/1000))
{
swosdDisplay(streamId, osdHndl);
osd_count[streamId] = 0;
}
else
osd_count[streamId]++;
SWOSD_MsgRecvHandler();
if(SWOSD_winDrawHandle(osdHndl, (short*)(pBufInfo))!=0)
{
printf(" SWOSD: SWOSD_winDrawHandle Failure................. \n");
return FAIL;
}
}
return SUCCESS;
}
static int swosdDisplay(int streamId, SWOSD_Hndl *osdHndl )
{
int i = 0;
swosdMakeWinString(streamId);
//swosdChangeXYParmDetail(streamId, osdHndl);
if(SWOSD_setBmpWinEnable(osdHndl, SWOSD_WINDOW_ONE, SWOSD_BMPWINENABLE)!=0)
{
printf(" SWOSD: SWOSD_setBmpWinEnable Failure................. \n");
return FAIL;
}
return SUCCESS;
}
static int swosdMakeWinString(int streamId)
{
if(SWOSD_setBmpchangeWinXYPrm(osdHndl, SWOSD_WINDOW_ONE, 0, 0)!=0)
{
printf(" SWOSD: SWOSD_setBmpchangeWinXYPrm Failure................. \n");
return FAIL;
}
return SUCCESS;
}
The input values of above are streamID=0; width=1280;height=720;framerate=30000; pBufInfo=capBuf[0].start
No error return, but the video have no logo display, just have the normal video stream, i don't know why, please help to comment this, thanks.
