How do I show a video in the tkinter window?
the code above will display an empty Tkinter window. Now, we can create a MyVideoCapture object inside the app class and use the width and height of the video source to create a canvas big enough to display the entire video: 1 import tkinter 2 import cv2 3 4 class App: 5 def __init__(self, window, window_title, video_source=0): 6 own.

How do I show a video in Python?
Let’s see how to play a video using OpenCV Python. To capture a video, we need to create a VideoCapture object. VideoCapture has the device index or the name of a video file. The device index is just the number to specify which camera.
How do I use tkinter video?
Use
- Import tkinter and tkvideo.
- Create the parent Tk() and the tag you’d like to use.
- Create the tkvideo.tkvideo object with its parameters (video file path, tag name, whether to loop the video or not, and video size)
- Start the player thread with .play()
- Start the main cycle of Tk.
Can I use OpenCV with tkinter?
Using the Tkinter Library, we can create an interactive application that uses OpenCV as an essential part of the application. To build the application, you need to install OpenCV on your local machine and make sure the Python Pillow package is pre-installed.
How do I use OpenCV and Tkinter?
We will need Tkinter to access our GUI functionality, along with PIL/Pillow’s Image and ImageTk classes to display the image in our GUI. The tkFileDialog allows us to browse our file system and choose an image to process. Finally, we import cv2 for our OpenCV bindings.
How do I watch a video in OpenCV?
In OpenCV, a video can be read using the source from a camera connected to a computer or by reading a video file. The first step in reading a video file is to create a VideoCapture object. Its argument can be the device index or the name of the video file to be read.
How do I import a video into OpenCV?
Play video from file
- import numpy as np.
- import cv2 as cv.
- cap = cv.VideoCapture(‘vtest.avi’)
- while cap.isOpened():
- # if the frame is read correctly, ret is True.
- if not ret:
- print(“Cannot receive frame (end of transmission?). Exiting…”)
- break.
Can we play video in Tkinter?
3 answers. You could use python-gstreamer to play videos (this works for me on Linux, but should work on Windows too). This requires python-gstreamer and python-gobject, I would recommend you use this all in one installer. The following code works for me with GStreamer 1.0 and Python 3 on Ubuntu 16.04.
What is CVUI?
cvui is a (very) simple user interface library built on top of OpenCV’s drawing primitives. Other UI libraries, like imgui, require a graphical backend (eg OpenGL) to work, so if you want to use imgui in an OpenCV application, you need to enable it for eg OpenGL.
What is ImageTk in PIL?
The ImageTk module contains support for creating and modifying Tkinter BitmapImage and PhotoImage objects from PIL images. A Tkinter compatible bitmap image. This can be used anywhere Tkinter expects an image object. The given image must have mode “1”. Pixels with value 0 are treated as transparent.
How to add a frame to a video in Tkinter?
We will use the Imageio library to store a video and get its metadata and also its frames. We will then use the PIL library to add that captured frame as an image into the Label() widget defined inside a Frame() widget.
How does the streaming function work in Tkinter?
The Stream() function is called recursively. This is done by using the .after() method to register callbacks. Define the window Tk as the root variable. Next, we create a Frame and a Label with the frame as the parent, the latter will be used later to display each frame of the video as an image.
How to open and display videos in Tkinter that you develop?
After some web research and experimentation, I found the following working solution (the snippet is just to demonstrate the approach, my implementation used is more complex): frame_image = ImageTk. PhotoImage(Image. fromarray(image))
How do you read a video in Tkinter?
We then define a variable to store the video path and call the imageio library’s .get_reader() method with the above variable as a parameter to read that video. Next, we calculate the FPS of the video using the .get_meta_data() method [‘fps’] and do some calculations for the result for greater precision.
