I'm trying to develop a video pipeline on the Zybo platform that takes HDMI video in passes it to a custom IP and outputs the new video through VGA. I manage to create a system that takes HDMI and passes the video straight out the VGA interface but when I add in the AXI stream to video IP blocks in I can't seem to get a video out of the VGA. I tried tying all the rst_n and enable on the vid_in_axi4s, axi4s_vid_out and tc off to one but still doesn't output any video on the VGA. I also output the locked signal from the axi4s_vid_out IP to one of the LEDs on the board and it never gets set high. Does anyone have any idea what I might have setup wrong or if I'm missing something?
