so im trying to display a video on a part with frames, and to do that, i need to get the frames, and to do that i need to do some python stuff, and its god dam slow, how would i fix the error?
Can you be more specific about what doesn’t work? The error itself and the code

heres the python function that im using to get the video pixels
def getVideoPixels(timestep):
timestep = int(timestep)
frame_count = int(vid.get(cv2.CAP_PROP_FRAME_COUNT))
videoPixels = []
timestamp = 1
def getPixelsFromFrame():
pixels = []
vid.set(1, timestamp)
res, frame = vid.read()
# print(res)
# print(timestamp)
height, width, channels = frame.shape
for x in range(0, width-1):
for y in range(0, height-1):
color = []
color.append(frame[y,x,2])
color.append(frame[y,x,1])
color.append(frame[y,x,0])
pixels.append(color)
return pixels
frames_to_get = math.floor(int(frame_count / timestep))
print(frames_to_get)
for i in range(0, frames_to_get):
timestamp = i
videoPixels.append(getPixelsFromFrame())
vid.release()
print('request fulfilled')
return videoPixels
full code:
from flask import Flask, render_template, request
import cv2
import math
vid = cv2.VideoCapture('videothing.mp4')
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/get_pixels<timestep>', methods=['GET', 'POST'])
def get_pixels(timestep):
if request.method == 'GET':
return str(getVideoPixels(timestep))
return render_template('index.html')
def getVideoPixels(timestep):
timestep = int(timestep)
frame_count = int(vid.get(cv2.CAP_PROP_FRAME_COUNT))
videoPixels = []
timestamp = 1
def getPixelsFromFrame():
pixels = []
vid.set(1, timestamp)
res, frame = vid.read()
# print(res)
# print(timestamp)
height, width, channels = frame.shape
for x in range(0, width-1):
for y in range(0, height-1):
color = []
color.append(frame[y,x,2])
color.append(frame[y,x,1])
color.append(frame[y,x,0])
pixels.append(color)
return pixels
frames_to_get = math.floor(int(frame_count / timestep))
print(frames_to_get)
for i in range(0, frames_to_get):
timestamp = i
videoPixels.append(getPixelsFromFrame())
vid.release()
print('request fulfilled')
return videoPixels
app.run(host='0.0.0.0', port=1111, debug=False)
(the function itself SHOULD work, but i think that it errors cause the function is tooslow)
python on devforum 
Not being a jerk, seriously, I don’t think this is a forum to help you on Python?? I think you might need to go to a python help forum for that kind of stuff…

Well, this isn’t a forum for helping users out on Python, so I think you should go to a python forum for this type of question

its erroring on the roblox studio side, i just want someone that knows httpservice or smth
Then, the code is intended to do a Http request to get a specific frame of a video? On a pixel base in order to rebuild the data as a “image/frame”
By doing that, its possible to “play” frame by frame any video you want inside a roblox experience?..
My only concern its about if that is allowed by Roblox…
the http request is supposed to return all the frame’s pixels as a json string, i dont know what do you mean by image/frame
maybe not frame by frame (at least for me)
yes this is a private project
Yeah, thats obvious, I mean, you got the data per pixel as a “table” etc, and you have enough data to re-create a “frame” of a video.
So its “posible” to Play any video inside a roblox game, cause you have the pixels table of every frame.
Maybe Im just overthinking, but, what is the goal of your system?
yeah??? except the fact that it currently use local host so it wouldnt work on published games
