Looking for information regarding how to configure RDMS between AJA HDMI to Jetson AGX Orin


I am looking for examples, or documentation, that describes how to make use of RDMA (GPU Direct) for the transfer of video frames captured on a AJA HDMI board and the iGPU on a Jetson. My Jetson is configured with Jetpack 5.1.2 and I have confirmed that RDMA is working throught he use of the testrdma command. However, I have been looking for either example code or documentation that describes how I actually configure an application allowing it to set up for RDMA and through CUDA access the copied data. Any example code, or links to documentation would be greatly appreciated!

Thanks in advance,



I just wanted to answer my own question, I found a document titled “GPUDirect for Video” under the AJA SDK documentation folder.

Hopefully this helps others who may be looking for it!


Thought I would also share where someone can find an example GPUDirect demo program. A couple of demo programs can be found in the AJA SDK under the demoapps/NVIDIA directory.



This should have been posted in the Jetson forums. What Jetson are you running?


Moving this topic to the Jetson AGX Orin forum.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
