Subject: Event Based time synchronization with ALSA
Date: Mon, 17 Jan 2005 11:50:28 +0100 [thread overview]
Message-ID: <41EB9874.4060407@hypersonic.it> (raw)
Hi all,
I'd like to develop a sip phone using alsa...
All the app is going to be event based (no_blocking io, poll).
One of the issues is how to read 20ms sample periods
to build an rtp packet
What I'd like to understand is if I can rely on interrupts (poll
read data available event) by HW in order to get accurate 50HZ
poll frequency or I must rely on poll timeout instead...
My goal is (as always :-) ) to reduce as much as I can latency...
In the case poll events would be enough what would be the
relevant sw_params api's?
Thank you very much
PL
