Hello All. I am new to Gstreamer and am struggling to understand the basics. After some research i learned about pipelines and how to use the inspect command to check for compatibility between elements. I want to create a stream from my jetson to another machine. In this case a ubuntu machine in …

i have a working example of how my code looks like right now. Just a simple loop with a getImage() that in the end lands in a GpuMat. I can download it into a cpu mat making it a cv::mat instead of a cv::cuda::GpuMat but this would reduce the framerate alot. However i am so desperate i would also ac…

Hi, Please refer to the sample: [image] Nano not using GPU with gstreamer/python. Slow FPS, dropped frames Jetson Nano Hi, Attached a sample for reference. Please follow the steps: 0. Install CUDA, tegra_multimedia_api samples through sdkmanager Down the script [s] htt…

Thank you for your answer. I already have opencv 4.5: >>> import cv2 >>> cv2.__version__ '4.5.1-pre' but trying to build the gst_cv_gpumat.cpp i get the following error: $ make all Compiling: gst_cv_gpumat.cpp g++ -I/usr/src/tegra_multimedia_api/include -I/usr/local/cuda/include -pthread -I/usr/l…

The path to jetson MM has changed. Turn -I/usr/src/tegra_multimedia_api/include into -I/usr/src/jetson_multimedia_api/include. Depending on your case, you may also try gstreamer NV plugin nvivafiter. You may find some examples searching this forum.

i don’t have that folder either: $ ls /usr/src/ cudnn_samples_v7 linux-headers-4.9.140-tegra-linux_x86_64 tensorrt cudnn_samples_v8 linux-headers-4.9.140-tegra-ubuntu18.04_aarch64 glibc nvidia used the following command to verify that its nowhere: $ sudo find / -name "*multi…

Does this only work with CSI cameras? I have a pcie camera.

Not sure how much easy or even possible it is to use argus for a PCIE camera, but this may require paid support. You may use the ximea/opencv example of post #2 that reads image into pinned memory from your proprietary camera software, then uses GPU for debayering. If you want to perform GPU proce…

Hi, In general, we install Jetson OS, SDK components through SDKManager and then execute the script: JEP/install_opencv4.5.0_Jetson.sh at master · AastaNV/JEP · GitHub Would suggest you try this.

Thank you for your reply. I already have openCV 4.5.1 installed. Why are you suggesting to try to reinstall it? This is not what this topic is about. I have a cv::cuda::GpuMat and want to get it into GStreamer. I already have all required libraries.

Hello Honey! I love reading your posts. Always top notch. I have it working with openCV::VideoWriter . But it is very slow. My Camera can do 30FPS with my settings. but the stream is below 5fps. I think its because the VideoWriter is using cpu to encode to h264. I struggled to make this work at a…

Yes, your writer pipeline uses x264enc that is CPU only. You may try this for RTP/UDP streaming.
