DRAM AND GSTREAMER

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,

Would you consider v4l2 on linux and v42l source element at GStreamer ?

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.
