[Live-devel] the computation of RTP timestamp

[Ross Finlayson]

>Can anyone tell me why it compute the timestamp this way? Why there is a 0.5?

We add 0.5 so that values whose integer fraction is >= 0.5 get 
rounded up, and values whose integer fraction is < 0.5 get rounded 
down - when the value is converted to an integer.

In any case, you shouldn't care about the RTP timestamp computation. 
Instead, you should treat it as a 'black box', into which you feed 
presentation times (at the sender end), and get back presentation 
times (at the receiver end).
