Gstreamer issue in detectNet tutorial

seiazetsu · October 16, 2020, 11:50pm

Hi, I need help. By following this tutorial

and running my-detection.py , I get the following error after a while and the program stops.

** (python3:17067): CRITICAL **: 08:43:07.729: gst_adapter_push: assertion ‘GST_IS_BUFFER (buf)’ failed
Segmentation fault (core dumped)

Could you tell me the solution?

Thanks,

Hi,

Do you have a CSI camera, which is directly connected to the Jetson board.
The default command is designed for the CSI camera.

Please note that the videoSource need to be updated into '/dev/video0' for a V4L2 camera (USB camera).

from jetson_inference import detectNet
          from jetson_utils import videoSource, videoOutput
          
          
net = detectNet("ssd-mobilenet-v2", threshold=0.5)
          camera = videoSource("csi://0")      # '/dev/video0' for V4L2
          display = videoOutput("display://0") # 'my_video.mp4' for file
          
          
while display.IsStreaming():
          	img = camera.Capture()
          	detections = net.Detect(img)
          	display.Render(img)
          	display.SetStatus("Object Detection | Network {:.0f} FPS".format(net.GetNetworkFPS()))

Thanks.
