[vlc] Re: obtaining time from a ts file

[Mark Moriarty]

Thanks -- it was the other file-oriented encapsulations that have the header
info which leads to a file duration (ASF, AVI, MOV,...).

I have to admit, WMP does a pretty quick start up, so the read-EOF mechanism
doesn't seem half bad for MPEG PS, differencing between the last PTS and the
first.  What's the downside?  Do some files have PTS that gets weird,
discontinuities?

Thanks again.

I can assure you, that there is nothing of the kind there.

That seems highly likely.
