Dear Community：

Can the time-stamp be saved for each frame of the video?

I use video.sh
gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw,format=UYVY,width=1920,height=1080,framerate=15” ! nvvidconv ! “video/x-raw(memory:NVMM),format=NV12” ! nvoverlaysink sync=false

Thanks

Hi,
The timestamps are stored in pts of GstBuffer. If you need the data, you can link to appsink and get pts of every frame.

Can the Xavier-NX system time be saved for each frame of the video?Thanks

Hi
Here is a sample of using appsink:
Gstreamer decode live video stream with the delay difference between gst-launch-1.0 command and appsink callback - #6 by DaneLLL

You may apply your pipeline and give it a try. Generally it generates timestamps in gstreamer framework. If you need the timestamps in kernel, maybe you can try jetson_multimedia_api. 12_camera_v4l2_cuda is the sample for capturing frames through v4l2.

Hi,
For information, do you use a YUV sensor connecting to CSI port on Xavier NX? Or a USB camera?

We use a YUV sensor connecting to CSI port on Xavier NX

Please reference to below topic for the timestamp transfer to kernel time the transfer to system time by your self.
