Running detectnet on AGX Xavier and can’t read video file.

The command is

./detectnet --input_URI=file:///opt/nvidia/deepstream/deepstream-5.0/samples/streams/IMG_5715.MOV --model=/home/xavier/Desktop/jetson-inference/platerecg/models/numplate_resnet_18_fp32.etlt_b1_gpu0_fp16.engine --labels=/home/xavier/Desktop/jetson-inference/platerecg/labels/labels.txt --input-blob=input_1 --output-bbox=output_bbox/BiasAdd --output-cvg=output_cov/Sigmoid --batch-size=1 --threshold=0.5 --overlay='box' --input-width=1920 --input-height=1080 --input-flip=none

Log infos are

xavier@xavier-desktop:~/Desktop/jetson-inference/build/aarch64/bin$ ./detectnet --input_URI=file:///opt/nvidia/deepstream/deepstream-5.0/samples/streams/central3.mp4 --model=/home/xavier/Desktop/jetson-inference/platerecg/models/numplate_resnet_18_fp32.etlt_b1_gpu0_fp16.engine --labels=/home/xavier/Desktop/jetson-inference/platerecg/labels/labels.txt --input-blob=input_1 --output-bbox=output_bbox/BiasAdd --output-cvg=output_cov/Sigmoid --batch-size=1 --threshold=0.5 --overlay='box' --input-width=1920 --input-height=1080 --input-codec=mpeg4

Even though --input_URI=file:///opt/nvidia/deepstream/deepstream-5.0/samples/streams/IMG_5715.MOV is set, loginfo shows that – URI: csi://0 and it is reading from device.

Need to input as
./detectnet file:///home/xavier/Desktop/jetson-inference/platerecg/IMG_5715.mp4.
