I doubt though we need another attribute on the element - the
information is stored in the src URL, so should be retrieved from
there IMHO.
In this case it is not stored in the src URL in a way the author of
the document can retrieve. An oggz-chopped file can be copied and
served with a normal filename for example. The time is embedded in
the
Ogg file. There is no way for the author to retrieve it. Hence the
need for an attribute.
Ah, yes, in this case it can only come from the file directly into a
DOM property. I see. I agree, there is a need for an explicit
attribute.
A media file with a non-zero initial time stamp is not new to oggz-
chopped files (eg. an MPEG stream initial PTS can have any value,
SMPTE time-codes do not necessarily start at zero, etc) , but I
disagree that we need a new attribute to handle it.
Media time values are expressed in normal play time (NPT), the
absolute position relative to the beginning of the presentation. It is
the responsibility of the UA to map time zero of the element to the
starting time of the media resource, whatever it may be.
