（1）camera link
（2）capture link
（3）两者区别
（1）camera link 走的是isp iss link采集的得到的数据，适用于ipnc 框架
（2）capture link 走的是vpss 里面的vip0 a，b vip1 a，b。适用于dvr，底层内核驱动是v4l2，在ti81xx_vpss.c中有代码，路径：\\192.168.0.144\Share\opt\exp_ipnc3.5\Source\ti_tools\ipnc_psp_arago\kernel\arch\arm\mach-omap2下
很经典啊，可以直接打开video0 设备取数据 ，然后用fb进行显示
16 bit decoders are present on the Port A of VIP0 and VIP1 instances. Which
represents the VIP0 and VIP2 instances in software. While Port B of VIP0 and
VIP1 are represented by VIP1 and VIP3 instances. On these two instances no
decoders are present.
* This is a sample for loopback application. This application captures through
* V4L2 capture driver on TVP7002 input, converts it to RGB using
* HDVPSS capture color space converter and displays the captured content
* on FBDEV
