Hello ひさやん,

 

 

Thanks for reaching out!

 

 

I would like to suggest you to check the Intel® Joule™ Module Datasheet on section 4 to learn about the Joule's video processing capabilities.

 

 

I'd like to emphasize a bullet from section 4.1:

 

 

"...Hardware capable of (up to) 4k video encode and decode; software dependencies exist..."

 

 

If you would like to know more about what video encode and decode mean, I'd suggest you to read the following:

 

 

https://en.wikipedia.org/wiki/Video_codec

 

http://stackoverflow.com/questions/4850817/main-difference-between-encoding-and-decoding-of-a-video-...

 

 

Even if the board has this capabilities it is important to note that it does not have an HDMI input.

 

 

Regarding your question about the library to capture video, there are several libraries available for this purpose, for example OpenCV ( http://opencv.org/).

 

 

I hope this information helps you.

 

-Peter.

Thank you for your quick reply.

 

I understand that if the board has this capabilities it is important to note that it does not have an HDMI input.

 

I refereed the Intel® Joule™ Module Datasheet.

and I have a new question.

4.3 HDMI* signal group specifications The Intel Joule module provides a HDMI 1.4b interface through the board-to-board connectors for expansion board usage. Refer to the Intel® Joule™ Expansion Board Design Guide for the specifications and PCB routing guidance for this interface.

Where is the Intel® Joule™ Expansion Board Design Guide ?

I googled it. but I couldn't find it.

Hi ひさやん,

 

 

We are still working on some public documentation for Joule. This specific document is not ready to be made public yet but hopefully it will soon be.

 

 

We apologize for any inconvenience this might cause.
