(1) Camera Link
(2) Capture Link
(3) Differences
(1) Camera Link uses the data collected by isp iss link and is applicable to the ipnc framework.
(2) Capture link uses vip0 A, B VIP1 A, and B in vpss. Applicable to DVR, the underlying kernel driver is v4l2, there is code in ti81xx_vpss.c, path: \ 192.168.0.144 \ share \ opt \ exp_ipnc3.5 \ source \ ti_tools \ ipnc_psp_arago \ kernel \ arch \ Arm \ mach-omap2
It's classic. You can directly enable the video0 device to retrieve data, and then use fb for display.
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
