Compiling link_api_demos in RDK4.0.1

Other Parts Discussed in Thread: TVP7002, TVP5158

Hi experts,

I am currently working on 8148 evm with RDK4.0.1. 

According to install guide, RDK provided some prebuilt application such as SD video capture --> encode --> decode --> display

and those demo application works now. 

In next step, I am going to do the video capturing via TVP7002, and I found there are some related keywords from ./demo/link_api_demos

but the make file does not compile the link_api_demos/ ....

So, I'm wondering if there's any reference could give a guidance for this? 

Thank you very much!

Sincerely,

    Hi Margarita,

    Thanks for your reply.

    Im trying to compile the link_api_demos under dvr_rdk/demos/..

    currently there are some errors during the compiling,  seems it does not link to RPE library,

    so I added  $(RPE_INC) in the ./link_api_demos/video_chains/MAKEFILE.MK,

    but this error is still occurs, any ideas ?
