rtp clarifications needed |
|
|
Hi,
i am a student and learning to implementing and
understanding rtp.
i am going thru the rtp code.
i got the logic in computing inter arrival jitter
(usual way as it is done in the rfc)
int transit = arrival - r->ts;
int d = transit - s->transit;
s->transit = transit;
if (d < 0) d = -d;
s->jitter += (1./16.) * ((double)d -
s->jitter);
what units is it in ?. timestamps or milliseconds.
i want to know how playout delay is computed (when
should be the next packet be played).
how jitter is used for this ?. can it be used ?.
How is the playout time computed from jitter
Please Advice,
Regards,
James |
