Delay acumulation with gstreamer and opencv

[DaneLLL]

Hi,
If your source is a video file, you may try this simple code:

Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv

Hi, We try to launch public RTSP source and it works fine: import sys import cv2 def read_cam(): cap = cv2.VideoCapture("rtspsrc location=rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw,format=BGR ! appsink ") if cap.isOpened(): cv2.namedWindow("demo", cv2.WINDOW_AUTOSIZE) while True: ret_val, img = cap.read(); …

It is RTSP source. For video file source, it should work by replace rtspsrc ! rtph264depay with filesrc. You may check if you observe the same accumulation in running it.
