Hi, I am trying to access the raw compressed frames/video data just before it is sent to the Smart Recording Module. Can anyone help me how to acheive that. My main target is to access the size of the compressed frames to trace the Iframe in the input RTSP stream.

What do you mean by Smart Recording Module?
Could you attach your pipeline?

I am talking about the Smart Record feature. Refer to this page -
https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_Smart_video.html
I wanted to know how I can get compressed frame meta data after the tee (from where the smart recording module takes the raw data). In meta data I mainly need the frame size(to track the IFrame) and the timestamp associated with that frame.

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

You can get the size from gstbuffer, you can refer the gstreamer guide:
https://gstreamer.freedesktop.org/documentation/gstreamer/gstbuffer.html?gi-language=c
