DM368 OSD显示图片/logo问题

各位，

我想在我的视频上叠加logo, logo我使用的是IPNC自带的默认数组，代码如下：

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;
}

其中streamID=0; width=1280;height=720;framerate=30000; pBufInfo=capBuf[0].start

我设置的SWOSD_setNumWindows(osdHndl, SWOSD_WINMAX) 用的SWOSD_WINMAX=28，参考代码原本的值

然后我所有函数都只有对SWOSD_WINDOW_ONE操作，其他窗口没有相关代码，这个可以只用一个窗口吧？？

运行没有出错返回，但是没有看到有logo出现，只有正常的采集过来的视频。。。

我是哪里出错了呢？搞不清楚为什么，需要什么其他的配置？还是库用错了？我用的是framework/alg/lib/alg_osd_ti.a ，这个可以直接用吧，还是需要重新编译的？

麻烦大家帮我解答一下，谢谢。
