Re: [Ccrtp-devel] Finding out packet timestamps

[Claude Brisson]

Does it mean that after evaluating the jitter for a given source, the
stack will wait for a short while after it receives a packet, and before
providing it to the app, to be sure it won't receive a newer packet ?

Otherwise I don't understand how the reordering can work. If packet 2
arrives before packet 1 and if getData(getFirstTimestamp()) is called
still before packet 1 is received, there won't be any reordering.

Can you give me some light ?
