There is Video Lag of Approx 2 Seconds in Jetson Orin when the video is captured using OpenCV Videocapture() But when the video is streamed directly in the gstreamer path, there is no lag in video. Also, the same scenario when tried in Jetson Xavier, there is no issue. There is no video ;ag in Xav…

For Orin, the Ubuntu 20.04 is the suggested OS version for host PC.

Hi, Do you use nvarguscamerasrc or v4l2src in your use-case? Would like to know the type of your source.

Hi, Looks like gstreamer is not enabled in the OpenCV. Do you use default OpenCV package installed through SDKManager?

Hi, still there is lag… But, the gstreamer is enabled Video I/O: DC1394: YES (2.2.5) FFMPEG: YES avcodec: YES (58.54.100) avformat: YES (58.29.100) avutil: YES (56.31.100) swscale: …

Hi, Please try gst-launch-1.0 command for comparison: $ gst-launch-1.0 rtspsrc location=rtsp://192.168.168.119:554 ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! 'video/x-raw(memory:NVMM)' ! nv3dsink see if the RTSP source can be decoded well in gst-launch-1.0 command and the issue is s…

Hi, [image] hamsal91295: rtsp://192.168.168.119:554 Please check if this URI is correct. Probably your RTSP source is changed.
