[Live-devel] Range Header

[Michael L. Boom]

Lets say I am 30 seconds into the clip I am watching.  If I say play "Range: npt=-60" it will return "Range: npt=0-" and play from the start.  When I use "Range: npt=now-60" it doesn't return a Range header but continues from where it left off and stops at 60 seconds into the commercial IF the scale is 1.0.  If the scale header is higher than 1.0 it will play way beyond 60 seconds (it does stop after a while though). 
Isn't the keyword "now" reserved for live events?

Basically "Range: npt=-60" doesn't seem to work but "Range: npt=now-60" does when the scale is 1.0.  When the scale is higher than 1.0 it does the same thing excepts plays way beyond 60 seconds into the clip.
