hi i am just trying to keep video frame using webcam in python GUI using tkinter module
how can i move video to down or to some other place in GUI and how to decrease the video show screen size
i am trying to change lmain = tk.Label(master=window) in main function to
lmain = tk.Label(master=window).place(x=500,y=500)
if i do that i am getting the following error
[ WARN:0] global C:\projects\opencv-python\opencv\modules\videoio\src\cap_msmf.cpp (674) SourceReaderCB::~SourceReaderCB terminating async callback

pic = cv2.cvtColor(last_frame, cv2.COLOR_BGR2RGB) #we can change the display color of the frame gray,black&white here
img = Image.fromarray(pic)
imgtk = ImageTk.PhotoImage(image=img)
lmain.imgtk = imgtk
lmain.configure(image=imgtk)
lmain.after(10, show_vid)
if __name__ == '__main__':
window=tk.Tk() #assigning window variable for Tkinter as tk
lmain = tk.Label(master=window)
lmain.grid(column=0, rowspan=4, padx=5, pady=5)
window.title("Sign Language Processor") #you can give any title
window.geometry("1366x768")
show_vid()
window.mainloop() #keeps the application in an infinite loop so it works continuosly
cap.release()
