TI中文支持网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

Louis：
可以把统计信息打印出来，进行分析，就是demo中的i选项。

回复 Louis:
这是打印信息，有什么问题吗
