A callback function can be setup to get the information of recorded video once recording stops. After decoding, there is an optional image pre-processing step where the input image can be pre-processed before inference. # default duration of recording in seconds. This function releases the resources previously allocated by NvDsSRCreate(). The inference can be done using TensorRT, NVIDIAs inference accelerator runtime or can be done in the native framework such as TensorFlow or PyTorch using Triton inference server.
