License PLate Detection

[sylia]

Hello,
Please I’m trying to test the repository Real-time-Auto-License-Plate-Recognition-with-Jetson-Nano/plate-detect.md at main · winter2897/Real-time-Auto-License-Plate-Recognition-with-Jetson-Nano · GitHub
when I execute the code detecnet-camera.py I get this error

i use this command :

 python3 detectnet-camera.py --model=./networks/az_plate/az_plate_ssdmobilenetv1.onnx --class_labels=./networks/az_plate/labels.txt --input_blob=input_0 --input-codec=h264 --output-codec=h264  --output_cvg=scores --output_bbox=boxes  --camera=file:///media/sylia/HDD/licenceplaterecognition/Real-time-Auto-License-Plate-Recognition-with-Jetson-Nano/data/video2.mp4 --width=1280  --height=720

Thanks

Hi,

The error reports a missing component.
Could you check if the h264parse exists in your environment first?

$ gst-inspect-1.0 h264parse

If it doesn’t exist, please try to install it via the following commands:

$ sudo apt install \
libssl1.0.0 \
libgstreamer1.0-0 \
gstreamer1.0-tools \
gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad \
gstreamer1.0-plugins-ugly \
gstreamer1.0-libav \
libgstrtspserver-1.0-0 \
libjansson4=2.11-1

Thanks.

Hi,
Please make sure you have contained the prebuilt libs listed in document, clean the cache and check again.

$ rm .cache/gstreamer-1.0/registry.aarch64.bin

If the plugins are still absent, we would suggest re-flash the system.
