Run Nvidia ALPR app on USB camera

Hi there,
I need to use the Nvidia ALPR application with a USB camera not MP4 video file.
Has any one done this before? or knows the procedure on how to do this?
I looked into the app, it looks complicated and I don’t know how to change it to run on a USB camera.

Any help is greatly appreciated.


Currently, this sample application(GitHub - NVIDIA-AI-IOT/deepstream_lpr_app: Sample app code for LPR deployment on DeepStream) only support mp4 files which contain H264 videos as input files.
