Capturing an image from the HDMI source on ZYBO

[birca123]

Hello,

I'm trying to make a standalone application for image processing on ZYBO, but I have problems with creating a block design which would make it possible. Since I started using Vivado two months ago, I'm still not familiar with creating my own block designs. I know that I should use dvi2rgb, Video In to AXI4-Stream and AXI VDMA IPs to store frames to DDR memory, but I don't know how to configure them. My idea is to create a function in Vivado SDK, e.g. CaptureImage(), which would return an address of the image saved in memory. 
Can somebody help me create the simplest block design to accomplish that?

Best regards,

Toni

Hi @birca123,

Here is a digilent forum thread that discusses making a HDMI pass through. Here is the GitHub HDMI pass through project that might be helpful. Here  is a digilent forum thread that discusses using SDSoC for image processing on the Zybo. Here is the SDSoC project for the Zybo.
