Tried to use opencv to open a .mp4 file in NVIDIA JETSON NANO using code:
import cv2
video_path = 'bird.mp4'
cap = cv2.VideoCapture(video_path)
if not cap.isOpened():
print("Error: Could not open video.")
exit()
while True:
ret, frame = cap.read()
if not ret:
print("Error: Cannot read frame.")
break
cv2.imshow('Video', frame)
if cv2.waitKey(25) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
But it does not work to preview the video file and gives error:
Opening in BLOCKING MODE
NvMMLiteOpen : Block : BlockType = 261
NVMEDIA: Reading vendor.tegra.display-size : status: 6
NvMMLiteBlockCreate : Block : BlockType = 261

Error: Could not open video.
The code works properly in my Windows PC to preview the video but not in JETSON NANO. Any suggestions to preview video file in using opencv on JETSON NANO?
opencv version: 4.9.0
