DVRRDK3.0 ，在demo的基础上改过两个简单的例子。
第一个例子 从capturelink----->display 能正常播放视频
第二个例子 capturelink-------->ipcFramesOutVpss---（nextLink)--->display
为什么这么设计，因为之前设计过一个复杂的capturelink----->ipcFramesOutVpss-----(processLink)--->ipcFramesInDsp--->Osd
------(nextLink)-------->display 无法正常播放，不报错，就是黑屏。
我把 capturelink-------->ipcFramesOutVpss---（nextLink)--->display 代码贴出来
