AGX Xavier DeepStream 6.1 Hi, Since yesterday i’m trying to modify this code : https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/tree/master/apps/deepstream-test1-usbcam which convert from NV12 to RGBA to make the video stream grayscale. The probleme is i cannot find an understandable Gstre…

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks You should add the caps after the nvvideoconvert. I have tried the cli: gst-launch-1.0 -e filesrc location=/opt/nvidia/deepstre…

You can refer the source code, use the capstilert to set the color format. Like: caps_vidconvsrc = Gst.ElementFactory.make("capsfilter", "nvmm_caps") caps_v4l2src.set_property('caps', Gst.Caps.from_string("format=GRAY8"))

Thanks for you replied, i tried your solution, it doesn’t show any error and it process correctly but image is still colored.

Here it is : pipeline.dot (9.2 KB)

You need add the capsfilter to videoconvert. You can create a new capsfilter and set the format. Then you link it after the videoconvert plugin.

[image] yuweiw: .set_property('caps', Gst.Caps.from_string("format=GRAY8")) I created a caps filter with Gray8 format : caps_gray = Gst.ElementFactory.make("capsfilter", "gray_caps") if not caps_gray: sys.stderr.write(" Unable to create v4l2src capsfilter \n") caps_gray.set_prope…
