[FFmpeg-user] EXT-X-PROGRAM-DATE-TIME usage

[kumar vikram]

Thank you for your prompt response.

I have gone through the wiki link. It talks about how the value in program
date time is mapped.
So looking at your responses I understand that this tag is more of
informative and should be used only to display current fragment date time
and should not be used to extrapolate pts and depend on demuxer only to
calculate pts.

Correct me if my thoughts are going haywire.

   The EXT-X-PROGRAM-DATE-TIME tag associates the first sample of a
   Media Segment with an absolute date and/or time.  It applies only to
   the next Media Segment.
[...]
   The client MAY use the value of the EXT-X-PROGRAM-DATE-TIME tag to
   display the program origination time to the user.
