How to include a succession of video frames in pygame window

I want to show a video using pygame by "pasting" its frames one by one within the while loop (one frame each iteration in succession). Something like this:

import pims
import pygame

pygame.init()    
gameDisplay = pygame.display.set_mode((500,800))
clock = pygame.time.Clock()

v = pims.Video('somevideo.avi')
run = True
while run:
# ... (here goes more code)

    gameDisplay.blit(v[k], (0,0)) # This function should show the kth video frame
    k = k + 1

# ... (here goes more code)

I have tried different variations of this code, but I can't get it to work.

Thank you very much

In what way does it not work? – Michael Bianconi May 21 '20 at 03:13
I get this error "TypeError: argument 1 must be pygame.Surface, not Frame". But it seems to work when I upload an image from my computer using the function "pygame.image.load()". But I can't get it to work when using a video frame (that should be the same as an image) – Rodrigo Guinea May 21 '20 at 03:18
A pims Frame is not the same as a Pygame Frame – Michael Bianconi May 21 '20 at 03:22
Is there a way to cast one into another? Because I looked for it with no luck – Rodrigo Guinea May 21 '20 at 03:23

A pims frame is a numpy ndarray. You start by looking there – Michael Bianconi May 21 '20 at 03:26
Oh, thank you. I already got it. For anyone with the same problem: First use "video_frame = pygame.surfarray.make_surface( v[k] )" and then "gameDisplay.blit(video_frame, (0,0))". – Rodrigo Guinea May 21 '20 at 03:30
