Holoscan SDK Compatibility with GMSL Cameras (e.g., ZED X Mini)

[w.schuiteman]

Hello,

We’re currently exploring the NVIDIA Holoscan SDK to better understand its advantages and how it might fit into our application pipeline. Specifically, we are working with cameras that use a GMSL connection, such as the
StereoLabs ZED x Mini

After reviewing the documentation and available examples, we haven’t found any clear references or demos showing Holoscan being used with GMSL-connected cameras.

• Is GMSL camera support compatible with Holoscan (directly or via V4L2/GStreamer)?
• Are there recommended approaches for integrating GMSL cameras into a Holoscan pipeline?
• Would it be better to use a different type of camera or connection for better Holoscan compatibility?

Any guidance, examples, or best practices would be greatly appreciated.

Thanks in advance!

Hi,
We do not have any existing GMSL support or camera.

To connect a GMSL camera you need a capture card to deserialize the video stream.
The capture card or adapter board will depend on the hardware you plan to work with. The jetson devices have different CSI connectors.

If you find a suitable adapter and see the camera through v4l2 with v4l2-ctl --list-devices you can ingest the videostream into Holoscan SDK applications through the V4L2VideoCaptureOp.
