Videos lagging

[Vishruth23]

Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

Yes

OS Platform and Distribution

MacOS

MediaPipe Tasks SDK version

No response

Task name (e.g. Image classification, Gesture recognition etc.)

Pose Estimation

Programming Language and version (e.g. C++, Python, Java)

Python

Describe the actual behavior

Rendered video extremely laggy, huge drop in FPS

Describe the expected behaviour

Rendered video should be smooth

Standalone code/steps you may have used to try to get what you need

import cv2
import mediapipe as mp
import time

cap = cv2.VideoCapture("PE-testcase2.mp4") # or VideoCapture(0)
mpPose = mp.solutions.pose
mpDraw = mp.solutions.drawing_utils

while True:
    success, image = cap.read()
    # cv2.imshow("Image", image)

    if not success:
        print("Ignoring empty camera frame.")
        continue

    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

    with mpPose.Pose(model_complexity=1, min_detection_confidence=0.5, min_tracking_confidence=0.5) as pose:

        imgRGB = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
        imgRGB.flags.writeable = False

        results = pose.process(imgRGB)

        imgRGB.flags.writeable = True
        imgRGB = cv2.cvtColor(imgRGB, cv2.COLOR_RGB2BGR)

        if results.pose_landmarks:
            mpDraw.draw_landmarks(imgRGB, results.pose_landmarks, mpPose.POSE_CONNECTIONS)
        
        cv2.imshow("Image", imgRGB)



cap.release()
cv2.destroyAllWindows()
