Hello,
I am using ULTRASCALE+ MPSOC which is xczu4ev-sfvc784-1-i family. I have camera which interface is LVCMOS and I want to capture live video.That's why I used DMA, DRAM IP cores. I can write and read data DRAM using AXI DMA. Moreover, I need to use GSTREAMER and unfortunately I cannot access the that video data by using GSTREAMER. How can I access the DRAM via GSTREAMER?
Can you help me?
Thanks.
Regards.

Hi @watari,
I am using actually PS DRAM inside the ultrascale mpsoc and I don't know how I will intagrate gstreamer and memory together. I store the camera data in the memory which is ps dram and I want to send these data to gstreamer. How gstreamer access the these data ı dont have any idea about this issue. Also this capturing the video process is done on petalinux.

Hi @erdincc

Would you consider v4l2 on linux and v42l source element at GStreamer ?
>Also this capturing the video process is done on petalinux.
How do you capture video stream ?
For example, if you captured video stream data by ex. yavta on petalinux, you already prepared v4l2 media graph.
Best regards,
