Hello. I need to save a high fps video, and get access to frames with python in real time for showing a preview with pygame or something similar. I´m trying something like this: cap = cv2.VideoCapture('v4l2src device=/dev/video0 ! image/jpeg, width=1920, height=1080, framerate=60/1 ! nvv4l2decod…

Hi, Looks like the performance is capped by CPU capability. You can run sudo tegrastats to get system status. Sine CPU capability limits performance performance it may not achieve 1080p60 while using OpenCV. We would suggest check if you can run standalone gstreamer command or use jetson_multimedi…

I found this, that preserve the original fps and reduce it for saving images, and work almost fine (I can’t reach the máximum fps in video). gst-launch-1.0 v4l2src device=/dev/video0 ! image/jpeg, width=1920, height=1080, framerate=60/1 ! nvv4l2decoder mjpeg=1 ! nvvidconv ! tee name=t t. ! omxh264…

Thanks! I had found this, that save video without VideoWriter: import time, cv2, threading def capturing(x): x=str(x) cap = cv2.VideoCapture("v4l2src device=/dev/video"+x+" io-mode=2 ! image/jpeg, width=1920, height=1080, framerate=60/1 ! nvv4l2decoder mjpeg=1 ! tee name=t t. ! nvvid…

I had enabled the four processors with: sudo nvpmodel -m 0 sudo jetson_clocks With this, trying to record 4 cameras 1080p60 with this: import time, cv2, threading def capturing(x): x=str(x) cap = cv2.VideoCapture("v4l2src device=/dev/video"+x+" io-mode=2 ! image/jpeg, width=1920, heigh…

Hi,
For this use-case, you would need to have cv2.VideoCapture() and cv2.VideoWriter(). Please refer to
