开发包DVRRDK3.5，DM8168.
我在3.5的包里面实现了单路、双路采集，然后添加osd并且显示的link，这个可以成功运行。但是同样的link放到4.0的开发包后就没有效果。
link流程是 ：
cap->merge->ipcFrameOutVpss->sclr->swms->disply
|->ipcFrameinDsp->osdprocess
两次的区别是，3.5的采集后输出的是420sp，osdlogo是 gMCFW_swosdTiLogoYuv420sp然后进入osd处理。
4.0的包是采集4路，然后输出422i送人osd处理，osdlogo是gMCFW_swosdTiLogoYuv422i。
我在4.0的包osdlink里面了打印信息，显示到已经执行了SWOSD_blendWindow(pSwOsdObj);函数。下面是一部分算法里面的打印信息：
[c6xdsp ] AlgLink_algProcessData | 178, enter alg process! [c6xdsp ] AlgLink_algProcessData | 198, enter osd! [c6xdsp ] AlgLink_OsdalgProcessFrame | 211, format is 0!

打印信息里面有个奇怪的地方是 pitch=448，这个值恰好是logo图像宽度的两倍，不知道是不是这个问题。
下面是link的创建代码：

}
请专家看一下，给点建议。谢谢了。
