I was running the pre-trained models using deepstream, but the input is video file by default . Is there a way to run the model and detect objects using usb cam in real-time, instead of outputting to the video file out.mp4? Currently: ./apps/tao_detection/ds-tao-detection -c configs/dssd_tao/pgie_…

From the log attached, the error is from the v4l2 plugin. So the most likely issue is the configuration of your camera. 1.You can refer to the link below to set the v4l2 source. https://github.com/NVIDIA-AI-IOT/redaction_with_deepstream/blob/8c51d49b084eb7bb04c38ffe843c95470916ce66/deepstream_reda…

Hello Yuweiw: Below are the camera parameters: ~$ v4l2-ctl -d /dev/video0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Type: Video Capture [0]: 'YUYV' (YUYV 4:2:2) Size: Discrete 640x480 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.042s (24.000 fps) Interval: Discrete 0.050s …

Your camera has 3 formats output from the list: YUYV, MJPEG and NV12. You can try to set the format to YUYV or NV12 (from the log and the image you attached before, although you set YUYV format, the actual setting is MJPEG). You can ask your camera vendor how to set it to YUYV or NV12 successfully. …

I can control the camera parameters of my Logitech Brio directly with the below command. However, how can I incorporate this into my code to initialize camera parameters ? gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUYV,width=1920,height=1080,framerate=30/1 ! nvvidconv ! 'video/…

You can set caps to the source by yourself. You can refer to our open source code: deepstream_source_bin.cpp case NV_DS_SOURCE_CAMERA_V4L2: bin->src_elem = gst_element_factory_make (NVDS_ELEM_SRC_CAMERA_V4L2, "src_elem"); bin->cap_filter1 = gst_element_factory_ma…

I can now permanently set the camera parameters using guvcview. See the below attached image for the parameters (and they do not change once I set them). I have also revised the caps in deepstream-gaze-app.cpp to match the camera parameters and built it using make. caps = gst_caps_new_simple ("vide…

How do you change the open souce code? And could you attach the log with GST_DEBUG=3?

I tried changing the open source code ( deepstream_source_bin.cpp) same as done in this post–> How to change source pixel format from YUYV to MJPG - #7 by jhchris713 However, I got the below log again when I use GST_DEBUG=3. Camera starts after 1 minute and between each new frame, nearly 3000 frame…

This latency test is for deepstream-app and in my case I have no problem running the deesptream-app . Both of my USB cameras work perfectly with deesptream-app and the latency is very low. See the log below: ************BATCH-NUM = 169************** Comp name = nvstreammux-src_bin_muxer source_id =…

[image] uersoy: This latency test is for deepstream-app The second item from the link is how to add latency to a separate app. 2.If you are using other deepstream sample apps such as deepstream-test3, you need to apply the following patch and set the env [image] uersoy: I tried the belo…

It’s only for deepstream-app, not for other apps,like deepstream-gaze-app.You should add patches to the source code, like: deepstream_gaze_app.cpp
2. Could you test the latency in your env?
