NTP timestamp on Jpeg images

Hi all,
i have a node js application that uses ffmpeg to receive an h264 stream
from a camera and convert to jpeg images.
the timestamp is overimpressed on the image and is extracted with an OCR
My goal is to remove the OCR and extract the NTP timestamp of the frame
I was told gstreamer has all i need but it seems too difficult.
For now i'm able to build a pipeline to write on file the single jpeg with
gst launch.
The problems i see are
1)extract the NTP timestamp, 2)synchronize with the jpeg,
3)put the timestamp somewhere (maybe metadata?)
4)Compile the application to be standalone without requiring to install

i'm not a developer so i need to know if this is doable for me or i need to
look elsewhere.
Any help is much appreciated
