amitmarathe If using Python is an option for you, you may want to look into using the "

opencv-python-headless" package which exists with prebuilt binaries for the aarch64 platform. Assuming you are running on the DK directly and not in a container, you can try the following:

1) Install pip3 with "sudo yum install pip3"

2) Install OpenCV (headless so we don't have additional dependencies for libGl or similar): "sudo pip3 install opencv-python-headless"

3) Prepare a Python script, this one is simply counting frames of a video

import cv2
import numpy as np

cap = cv2.VideoCapture("/path/to/your_video_file.mp4")
if not cap.isOpened():
    print("Could not open file")

frame_count = 0
# Read until video is completed
while(cap.isOpened()):
    # Capture frame-by-frame
    ret, frame = cap.read()
    if ret == True:
        frame_count += 1
    else:
        break

cap.release()
print(f"Frames: {frame_count}")

4) Run it, e.g. "sudo python3 video.py"
