Hello, I’m encountering an issue with nvarguscamerasrcon a Jetson platform (nvidia-jetson-kernel_src-linux-36.4.4-jetpack-6.2.1, orin nx). When I try to capture video using a GStreamer pipeline, the pipeline fails with a dmabuf_fdmapping error, even though the same camera works correctly with v4l2-…

Just check internally looks like current in Argus: RAW10 and RAW12 on different virtual channels sharing the same CSI port are not supported simultaneously by Argus

Hello @1984979292 ! Based on the title and content of your topic, it looks like it may receive better visibility and feedback in a different category. We took the liberty of moving it for you. If this was an incorrect assessment, please send me a direct message. Disclaimer: this moderation suggest…

The tegra_sinterface should be serial_a instead. mode0 {/*mode 2560x1984@30fps*/ status = "okay"; mclk_khz = "24000"; num_lanes = "4"; tegra_sinterface = "serial_e"; phy_mode = "DPHY"; vc_id = "3"; discontinuous_clk = "no"; dpcm_enable …

This issue has been resolved. Thank you very much.

Sorry to bother you again, I have one more question. When I use gst-launch-1.0 to get images from video0 and video1 separately, both work fine. But when I try to start both streams at the same time, the second one fails to start. Why is this happening? Below is the run log. Please help me translate …

I would suspect the incorrect virtual channel ID cause the problem.

Could you please point out the specific location? Currently, the hardware connection is set up with all four cameras connected via Port A. Thank you very much.

You need to make sure the vc-id match to the aggregator’s output.

I found that I changed the four dpcm_enable = "false";settings to dpcm_enable = "true";, and then I was able to use gst-launch-1.0to run video2 and video3 simultaneously for image capture. However, I cannot run video0 and video1 together with video2 and video3 to capture images at the same time. I’m…

Each of them working well indivitually?

Yes, they can run independently with gst-launch-1.0. Cameras of the same type can run together, but cameras of different types cannot run together. The four connected cameras consist of two 2064x1552, RAW12 cameras and two 2560x1984, RAW10 cameras.
