The source for that project is built using ISE/EDK, which has been succeeded by Vivado. We are currently designing a video input/output demo in Vivado that also incorporates additional features. Rather than teach people to use the old tools, we will instead fully document the source for the new project in Vivado. I describe the upcoming video project a bit more in this post: 


This new project will not include the Linear filtering and colorspace conversion cores used in the GoPro project, but I've made a To Do item to port these two cores from EDK to Vivado, document them, and add them to this library: https://github.com/DigilentInc/vivado-library. That repository will be where we post all of our custom Vivado cores in the future so that people can add them to their own designs as needed. After this, if there is enough demand, we will consider creating a tutorial that recreates the GoPro application by adding these cores to the Vivado Video input/output project.


Timelines on these items are pretty gray. We will do our best to get them out as soon as possible, and for updates on expected times, you may contact [email protected]

okay, good to know...


please could you keep it small or publish as part works?


feature creep seems to be particularly prevalent in vhdl, ie publishing monolithic projects without comments.

this naturally makes them rather harder to use....

Hi Sam,

     Sorry to bother here since I have post so many questions recently on this forum.

     But I do find that what you mentioned here is the most urgent thing for newbies like me who has very limited experience on FPGA design.

     I found tons of documentations and answers for knowledge related to the GoPro project. Currently I'm trying to pass the signal through HDMI -> FPGA -> VGA. And the docs here in https://github.com/DigilentInc/vivado-library and discussions here https://forum.digilentinc.com/topic/560-help-with-a-zybo-video-design/#comment-1832  are extremely useful. 

     However, none of the information is complete and solid. Especially when different IPs are put together, it is hard to figure out where the problem is. I am wondering if there is any tutorial that goes through a simple example like HDMI -> FPGA -> VGA? If there is, I think it will be the best foundation for people who start to do video processing on Zybo.


    Thank you very much!!

Hi Abdelkader,

I'm not aware of any ip cores that facilitates and edge detector into this type of design. We found this here that works with simulink if that is an option.  If you are not set on using baremetal designs or ip cores then another approch would be installing linux and use the opencv library like described here with a tutorial here. The tutorial is in spanish but my browser translated it to english. Hope this helps!
