It's a different case: in dvd streams there are additional time informations embedded
in the stream itself, maybe in some network stream too.
MPEG streams have broken timestamps by design that must be complemented  by some
sideband information (as in dvds).

The obvious fix is:
-start the stream time at 0
-keep track of the time difference between the last saved pts and the current one
  provided that the difference is not higher than 1 second. If it's higher increase
  it by .... what amount? every value is totally arbitrary


As you can see the stream time will never be precise and for this reason the user should never
be allowed to stream_seek in it.

Every now and then this request pops up and some patch is posted, but people don't seem
to realize that a method like the above is fundamentally imprecise, thus broken.
