Description Wouter Paesen 2005-07-02 21:11:20 UTC 
Please describe the problem:
For a perfect audio stream it should at all times be true that

     timestamp(n) + duration(n) == timestamp(n+1)

Audioscale breaks this due to rounding errors in the implementation.

Steps to reproduce:
I'll attach a simple testcase for this

Actual results:


Expected results:


Does this happen every time?

Whoa, dude, this is a lot of code change for such a simple rounding error.
Anyway, from some tests, it works fine still, and after some review, it seems
all correct, so applied... Some more explanation would be nice next time. :).
