Video Input Board (LI-VI365) does not work

Posted by kaanyilmaz

Hi,

I have Leopardboard 365 ver1.4 and LI-VI365. I have installed RR SDK. But I could not make Video Input Board work. There is no /dev/video0. So I guess there is a problem, maybe a driver problem. I need to get composite input from Video Input Board and record the video to an mp4 file, or stream the video from udp.

Is Video Input Board work with RR SDK on leopardboard 365? If yes, what are the boot args, and the gstreamer pipeline? And should I install any other driver or something other than RR SDK?

Thank you,

Kaan

Hi Kaan,

At this time RidgeRun only have support for the composite in video LI-VI365 board in our professional SDK.

You might check

arago-project.org/.../projects

and

arago-project.org/.../examples-davinci.git

as I have seen some drivers and demo apps checked in there.

I also want to record video by using LI-VI365. I did some steps to get it. I have modified board-dm365-leopard.c by adding tvp5146 chip. To capture data from tvp5146 it is also necessary to set the variable from bootargs to vpfe_capture.interface=0. This is described inleo365/kernel/linux-2.6.32/drivers/media/video/davinci/vpfe_capture.c. Now I am not sure about pin multiplexing because the tvp5146 on my board is quite hot after few minutes running. Where are the pins settings configured? Below I added board-dm365-leopard.c file.

I will be greatful for any suggestions.

Thank you Marian.

I have checked board-dm365-leopard.c and saw that it is same as your. So I did not modify the code.

I set vpfe_capture.interface=0 as you said. But still there is no /dev/video0. could you send your gstreamer pipeline for capturing from video input board?

As I am new to leopardboard and embedded devolopment, I do know know about pin multiplexing configuration. But my tvp chip is also hot.

Thanks.
