How to write a new link for dm8168 rdk to separate our own mux video signal？

Hi，

we develop on dm8168 dvrrdk 2.80.

we design our own board. 

we mux 2 XGA 60 video using FPGA in our own format， and after that we have to separate  two streams,

so a new link is needed, 

how to to then?

i read the dup link, but i am not familiar with link framework,

can someone tell me how links works deelpy

best regards

xavier

    Can you pls explain your usecase data flow.For example Capture -> NSF -> Encoder . Based on your description it does not look like you need a new link. I understand you are going to capture 2 channel XGA @ 60 fields / sec . Is that correct ? Is you question how to capture the video frame or have you already done that ? For capturing video, you will have to configure the external video decoder (FPGA in your case) and then configure capture link. you dont have to create  a new link. For configring capture link you will have to provide info on how the two channels muxed video format. (Pixel Muxed/Line muxed).(EMbedded Sync/Discrete Sync).It may require some changes in capture link file.
