I want to send video camera frame from Pynq-z2 Jupiter notebook to the FPGA PL side and vice-versa. So how do I create video IP in PL and process that in PS? Any kind of suggestion is welcomed. Thanks

Hi @dpk1 , Did you check the composable overlay? [image] The Composable Video Pipeline Announcements Hello PYNQ aficionados, Edit 10 March 2022: comments closed to request support open a new post in the support category . I am pleased to announce that the PYN…

Hello, Here is some code I put together using some references (noted in the code) that sends 800x600 frames from my USB webcam to the PL. On the PL side, it makes video frames from them and sends it out the HDMI output. This runs on my ZCU104. # https://discuss.pynq.io/t/webcam-video-to-hdmi-outp…

Is this only for HDMI_in camera? This pynq.lib.video is a way to call the video IP which is build on PL into the PS? I want to send frame of any type of camera to the PL. Thanks

That code is using the OpenCV capture device (i.e. a USB webcam), not HDMI-IN. This code would copy HDMI-IN to HDMI-OUT (without using the PS) #https://stackoverflow.com/questions/59578954/pynq-z1-how-to-stream-a-video-from-hdmi-input-to-hdmi-output-using-base-overla from pynq.overlays.base imp…

Thank you for your response. Just to confirm, This "from pynq.lib.video import * " library is used to transfer frames between PS and PL? Also Video Pipeline IP is built in PL side. By using pynq.lib, we are accessing that IP using PS jupiter notebook. Is it so? Is this method work for all types o…

Any support on how to create IP for Video camera in VIVADO and use of that IP in PS using jupiter notebook? Thanks

Hii, I am having issue while installing composible overlay package. When I am doing “pip install PYNQ_Composable_Pipeline/” , pynq-2.7.0.tar.gz is installing and it is giving me error “ERROR: Package ‘pynq-composable’ requires a different Python: 3.6.5 not in ‘>=3.8.0’”. I am using pynq-z2 and imag…

Hi @dpk1 , The latest version of the composable overlay depends on PYNQ 2.7. You will need to burn an SD card with PYNQ 2.7. Mario

Thanks, pynq 2.7 worked. I want to confirm one thing, Is this composable overlay using OpenCV for accessing video frames or video IP is built on PL and we are accessing that IP in PS?

Hi, OpenCV is only used to capture frames from a webcam or file in the PS. Then quickly moved to PynqBuffer. All of the vision function implemented on hardware are accelerated hardware version of their corresponding OpenCV counterpart. Mario

Hi @dpk1,

Did you check the composable overlay?
