You should start with something like the following:
$ ffmpeg -f gdigrab -i desktop -vcodec

Given the discussion above and the question under discussion, can you
please give a command to achieve the accurate timestamping of the frames?
Or suggest any other solution. Thanks.

This filter chain looks either useless or broken.

It is only needed if 60fps recording is wanted.
As said before, setpts should generally be avoided and
this is even more true for

It is only needed if 60fps recording is wanted.
As said before, setpts should generally be avoided and
this is even more true for settb. If you have to smooth
timestamps, use

@Mark: I have tried to modify the setts and setpts options. Below is the

So I have modified to recording resolution and applied the offset to
capture only the area of interest. It speeds up the capturing of timestamps
and I am getting a timestamp on each frame at an interval of (14ms to
18ms). Which is close to ideal 16.6msec for 60 FPS recording, yet not
accurate
