The old version has some problems, you can download the new version by: https://github.com/RongSong1993/YOLOv3-SaveVideo-New/tree/master
Update: The new version can be obtained in:https://github.com/RongSong1993/YOLOv3-SaveVideo-New/tree/master
The original YOLOv3 version can be obtained from the website：https://pjreddie.com/darknet/yolo/, but it does not save the output video which is detected by default.
So, this project gives a complete project which can save you output video,include your local test video and your webcam's test video. Only two files have been changed,include (./darknet/src/demo.c) and (./darknet/src/image.c). So,you can only change them in your YOLOv3 project.
Attention: Beacause the （./darknet/yolov3.weights） takes up too much memory space,so this project doesn't include the model,you can download it in the website：https://pjreddie.com/darknet/yolo/.
