[vlc] Re: obtaining time from a ts file

[Mark Moriarty]

I'm not sure, but there's something there.  When I open a 3.7GB MPEG PS .mpg
movie in WMP, it opens virtually instantaneously, and I get a slider showing
proper duration.  The disk isn't grinding away.

Um, really?  Do you know what the structure is called?  I ask because I've
got a program that figures out the length of an MPEG-2 PS, and it simply
counts frames.  On the gigabyte-plus videos we typically deal in, this takes
a long time.  If there's a single place I can look for the time, that would
be very nice.

Naturally, VideoLan could do what I did with TS streams.  Probably the
reason it isn't done now is that it's an O(n) algorithm.
