I get this while trying to run : LD_LIBRARY_PATH=./:$LD_LIBRARY_PATH ./uselib data/coco.names cfg/yolov3.cfg yolov3.weights data/input.mp4

There is no output file or window opening. Can you please help me with this issue?

Also, is there an option to not show the video in the window but save it to drive for object tracking ?

It looks like there is no data/input.mp4 file or you haven't compiled OpenCV with FFMPEG support.
