（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

（3）8148 没有camera link

 双port 不能同时采集问题
