For example, I type： python yolo_video.py [1.mp4] or python yolo_video.py [C:\Users\keras-yolo3\1.mp4] response is : model_data/yolo.h5 model, anchors, and classes loaded. warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:808) warning: [1.mp4] (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:809) Traceback (most recent call last): File "yolo_video.py", line 16, in detect_video(YOLO(), video_path) File "C:\Users\keras-yolo3\yolo.py", line 167, in detect_video raise IOError("Couldn't open webcam or video") OSError: Couldn't open webcam or video

MartinWeniger commented 6 years ago

hi, i had the same problem, to solve it i had to change the following code part in the yolo_video.py: def detect_video(yolo, video_path, output_path=""): import cv2 vid = cv2.VideoCapture(video_path) if not vid.isOpened():

with this part: def detect_video(yolo, video_path, output_path=""): import cv2 import os

VIDEO_NAME = 'VIDEONAME.flv'
# Grab path to current working directory
CWD_PATH = os.getcwd()
PATH_TO_VIDEO = os.path.join(CWD_PATH,VIDEO_NAME)
vid = cv2.VideoCapture(PATH_TO_VIDEO)
if not vid.isOpened():

with the code the video have to be in the same folder as the yolo_video.py After this u can start with python yolo_video.py agafefkjvne(or anything else ;-)

MartinWeniger commented 6 years ago

also u can change

def detect_video(yolo, video_path, output_path=""): import cv2 vid = cv2.VideoCapture(video_path) if not vid.isOpened():

to this:

def detect_video(yolo, video_path, output_path=""): import cv2

pfad="C:/FOLDERNAME/NEXTFOLDERNAME/VIDEONAME.flv"
vid = cv2.VideoCapture(pfad)

so ur videofile can lay where ever u want it to lay :-D

PS: sorry for my english

YuhaoYeSteve commented 6 years ago

Thanks a lot! MartinWeniger You really help me a lot!

YuhaoYeSteve commented 6 years ago

I made a small demo by using this library and a street dance video. See here: https://www.youtube.com/watch?v=XyInRQF3mq4

MartinWeniger commented 6 years ago

nice it looks good. By the Way, i have something similar to yours. When im done i post it too. ;-)

YuhaoYeSteve commented 6 years ago

haha, thanks for your help with the initial read in video problem, can't make it without your help

MartinWeniger commented 6 years ago

You are welcome

@MartinWeniger @YuhaoYeSteve Hello guyz, I encountered the same error :

Traceback (most recent call last): File "yolo_video.py", line 75, in detect_video(YOLO(**vars(FLAGS)), FLAGS.input, FLAGS.output) File "/home/yaser/Downloads/keras-yolo3-master/yolo.py", line 176, in detect_video raise IOError("Couldn't open webcam or video") OSError: Couldn't open webcam or video

I tried to fix it by changing the file yolo_video.py but I didn't find the section that you mentioned which is:

def detect_video(yolo, video_path, output_path=""): import cv2 vid = cv2.VideoCapture(video_path) if not vid.isOpened():

any idea where I can find it?

MartinWeniger commented 6 years ago

@YasserTahaSW the Error comes from line 176 in the yolo.py file. There u have to make the changes

yas-ml commented 6 years ago

@MartinWeniger Thanks a lot! I wrote these lines as you mentioned: def detect_video(yolo, video_path, output_path=""): import cv2 pfad='path_to_my_video.mp4' vid = cv2.VideoCapture(pfad) if not vid.isOpened(): but the problem was still there. because the ."VideoCapture" didn't work.

I then had to install opencv-python (not supported by opencv dev team) and then run again with your code and it worked fine.

Thanks again

MartinWeniger commented 6 years ago

sounds good :-D

nuannuan1991 commented 6 years ago

@MartinWeniger @YuhaoYeSteve I modified it according to your code, while there is an error. def detect_video(yolo, video_path, output_path=""): import cv2 VIDEO_NAME = 'video1.mp4' CWD_PATH = os.getcwd() PATH_TO_VIDEO = os.path.join(CWD_PATH,VIDEO_NAME) vid = cv2.VideoCapture(PATH_TO_VIDEO)

pfad="/media/wy/软件/github/keras-YOLOv3-mobilenet-master/video1.mp4"

# vid = cv2.VideoCapture(pfad)
if not vid.isOpened():
    raise IOError("Couldn't open webcam or video")

my order is python yolo_video.py [video1.mp4] or python yolo_video.py [1.jpg] I have tried this error many times and I am grateful for your help.

MartinWeniger88 commented 6 years ago

@nuannuan1991 i need a little bit more information to help u -which error do u get? -is your video file in the same folder?

nuannuan1991 commented 6 years ago

hi @MartinWeniger my order is:python yolo_video.py [video1.mp4] yolo_video.py: error: unrecognized arguments: [video1.mp4]

if my changed to:python yolo_video.py [model_data/yolo_face.h5][model_data/face_anchors.txt][model_data/face_classes.txt][video1.mp4] it has the same error： yolo_video.py: error: unrecognized arguments: [model_data/yolo_face.h5][model_data/face_anchors.txt][model_data/face_classes.txt][video1.mp4] My video and yolo_video.py are in the main folder.

capture when i change the code as you mentionned i get this error

MartinWeniger commented 5 years ago

Hi @cyrineee, The Error message says that u used ur tabs and spaces inconsistent. Python is really strict with using tabs and spaces, so i think the solution for ur Problem is the use it correctly. Maybe ur using a tab and a space at an Line in ur code, or u have used an tab on one line and on an other line u have used spaces.

and in CMD command, write: python yolo_video.py --input

The accompanying repository works on MacOS, Windows and Linux, includes multigpu and multithreading, performs inference on images, videos, webcams, and an iOS app. It also tests to slightly higher mAPs than darknet, including on the latest YOLOv3-SPP.weights (60.7 COCO mAP), and offers the ability to train custom datasets from scratch to darknet performance, all using PyTorch :) https://github.com/ultralytics/yolov3

hello. i am a primary learner.when i did what you said,it occur a new problem. AttributeError:'YOLO' obeject has no attribute 'sess' thank you!

Enki08 commented 4 years ago

I've got a solution here: in file yolo_video.py Line55, just replace the path to your full path, remember, full path!

for example:

 parser.add_argument(
        "--input", nargs='?', type=str,required=False,default='D:/keras-yolo3-master/video/0.mp4',
        help = "Video input path"
    )

or in commond line in your env: python yolo_video.py --input D:/keras-yolo3-master/video/0.mp4
