Yukarıdaki konuyla alakalı bir soru opencv ile açtığım bir videoyu tkinter içine gömebilir miyim?
Merhabalar,
Diğer başlıkta verilen resim eklemekle alakalı yönteme ilaveten, başka kodlar da paylaşmak istiyorum:

def select_image():
# grab a reference to the image panels
global panelA, panelB
# open a file chooser dialog and allow the user to select an input

# OpenCV represents images in BGR order; however PIL represents
# images in RGB order, so we need to swap the channels
image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
# convert the images to PIL format...
image = Image.fromarray(image)
edged = Image.fromarray(edged)
# ...and then to ImageTk format
image = ImageTk.PhotoImage(image)

# if the panels are None, initialize them
if panelA is None or panelB is None:
# the first panel will store our original image

# otherwise, update the image panels
