This point is Frame source image? or this struct header?
May I use this pts to get source image(RGB) and save *.png

Hi,
buf_pts is ‘buffer presentation timestamp’.

For dumping frames, you may enable dsexample. Please check

deepstream_sdk_v4.0_jetson\sources\gst-plugins\gst-dsexample\README

Here is a sample of saving to jpg.
