My task is to display a webcam stream and its black&white stream in two different frames on a single GUI using Tkinter on python. I have seen some examples on google, but they are of images not videos as in the link here. Example of image display in 2 panes on a single GUI
I need exactly the same thing but for the real time video through my webcam.
Initial question:
"I am having issues in displaying multiple (2) windows for displaying video frames in a GUI using Tkinter in python. Please help me with a
code for this task."
The initial question mentioned 2 windows so here's a basic example on how to create multiple windows with tkinter:
#import tkinter as tk
import Tkinter as tk
class MainWindow(tk.Tk):
def __init__(self, *args, **kwargs):
#super().__init__()
tk.Tk.__init__(self)
self.title("This is the MainWindow")
self._is_hidden = False
self.window1 = OtherWindow(self, title="window 1")
self.window2 = OtherWindow(self, title="window 2")
def toggle_hide(self):
if self._is_hidden:
self.iconify()
self.deiconify()
else:
self.withdraw()
self._is_hidden = not self._is_hidden
class OtherWindow(tk.Toplevel):
def __init__(self, master, *args, **kwargs):
#super().__init__(master)
tk.Toplevel.__init__(self, master)
if 'title' in kwargs:
self.title(kwargs['title'])
self.hide_main_button = tk.Button(self, text="Hide/Show MainWindow")
self.hide_main_button['command'] = self.master.toggle_hide
self.hide_main_button.pack()

This code works under normal circumstances but I haven't handled situations where one video ends and the other is still playing. Also, the audio has not been handled in this code.
I created two canvases in the same window and ran the video as a series of images. I have resized the video to fit a constant canvas size but you can change the canvas size to fit the video if you want.
You can change the source to be from your webcam.

I tried to dynamically display multi live camera in python tkinter with threads.

I created a master window in tkinter.... then when I press a button on master window it will open another top level window in which I created a canvas and a button....
Canvas for: reading camera frame by frame and show it in tkinter window
Button for: capture the current frame..but in button I used face detection to detect a face when it detects a face I want close the top-level window and go back master window

When I run this code, nothing happens. I get no window but I do know it is updating the panel (I've tested it with printing messages). Could there be permissions problem for accessing the camera and things like that?

How to add a cv2 trackbar to a Tkinter window?
I have 2 snippets of code that my teammates have made, but it is difficult to integrate them in the same window.
I am able to use them in separate windows but I want to use them in the same window.
CODE FOR THE VIDEO PLAYING IN TKINTER:
import cv2
import tkinter as tk
from tkinter import *
# from tkinter import ttk
# from ttk import Frame
# import ImageTk
white = "#ffffff"
lightBlue2 = "#adc5ed"
font = "Constantia"
fontButtons = (font, 12)
maxWidth = 800
maxHeight = 480
#Graphics window
mainWindow = tk.Tk()
mainWindow.configure(bg=lightBlue2)
mainWindow.geometry('%dx%d+%d+%d' % (maxWidth,maxHeight,0,0))
mainWindow.resizable(0,0)
# mainWindow.overrideredirect(1)
mainFrame = Frame(mainWindow)
mainFrame.place(x=20, y=20)
#Capture video frames
lmain = tk.Label(mainFrame)
lmain.grid(row=0, column=0)
cap = cv2.VideoCapture('test.mp4')
def show_frame():
ret, frame = cap.read()
cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
img = Image.fromarray(cv2image).resize((760, 400))
imgtk = ImageTk.PhotoImage(image = img)
lmain.imgtk = imgtk
lmain.configure(image=imgtk)
lmain.after(10, show_frame)
closeButton = Button(mainWindow, text = "CLOSE", font = fontButtons, bg = white, width = 20, height= 1)
closeButton.configure(command= lambda: mainWindow.destroy())
closeButton.place(x=270,y=430)
show_frame() #Display

I have to integrate the cv2 trackbar into the Tkinter window.
I am able to integrate but as I don't know how to use implement CV2 trackbar in tkinter, I am not able to do anything.
Please Help.
Try using tkinter Scale widgets instead of cv2 trackbars. They are slightly different but they should be fairly easy to swap out and work about the same. Then you can easily add them in your tkinter window/frame.
I am using a webcam view and performing analysis on the images taken in. I wish to introduce a functionality where a window can be summoned and the user can look at the webcam view in a new window, should they desire. However my attempt causes buttons in my main window to swap over to the instance when I open up the new window. What's going wrong?
Here is my (working) example:
import Tkinter as tk
import cv2
from PIL import Image, ImageTk
class CamView():
def __init__(self, parent):
self.parent = parent
self.window = tk.Toplevel(parent)
self.window.protocol("WM_DELETE_WINDOW", self.close)
self.show_frame()
def show_frame(self):
imgtk = ImageTk.PhotoImage(image=self.parent.img)
lmain.imgtk = imgtk
lmain.configure(image=imgtk)
def close(self):
self.parent.test_frame = None
self.window.destroy()
root = tk.Tk()
root.bind('<Escape>', lambda e: root.quit())
lmain = tk.Label(root)
lmain.pack()
class Main(tk.Frame):
def __init__(self, parent):
self.test_frame = None
frame = tk.Frame.__init__(self,parent)
a = tk.Label(text='hello!').pack()
b = tk.Button(frame, text='open', command=self.load_window)
b.pack()
width, height = 800, 600
self.cap = cv2.VideoCapture(0)
self.cap.set(cv2.CAP_PROP_FRAME_WIDTH, width)
self.cap.set(cv2.CAP_PROP_FRAME_HEIGHT, height)
self.do_stuff()
def do_stuff(self):
_, frame = self.cap.read()
frame = cv2.flip(frame, 1)
cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
self.img = Image.fromarray(cv2image)
if self.test_frame != None:
self.test_frame.show_frame()
lmain.after(10, self.do_stuff)
def load_window(self):
self.test_frame = CamView(self)
control = Main(root)
root.mainloop()
In my real code, as well as this working example - it seems that when I load the new window, it places the webcam frame in the first window when I don't want it to!
Fixed! I was getting confused because of self.lmain. Here is the working code:
import Tkinter as tk
import cv2
from PIL import Image, ImageTk

self.parent = parent

a = tk.Label(text='hello!').pack()
b = tk.Button(frame, text='open', command=self.load_window)

width, height = 800, 600
self.cap = cv2.VideoCapture(0)
self.cap.set(cv2.CAP_PROP_FRAME_WIDTH, width)
self.cap.set(cv2.CAP_PROP_FRAME_HEIGHT, height)
