[Freeswitch-users] mod_portaudio send 3 rtppacket/60msinsteadof1 packet/20ms

Wed May 7 11:13:58 EDT 2008

I get always 3 RTP packets at once with 60ms setting, i also test with
PCMU at 60i in vars.xml but i always get 20ms packets with 160byres packet
size.

Anthony, you are right with you "timeout assumption". To illustrate,
here a log from my patch without waiting, i. e. no functional
difference:

So i want use the timer to prevent these buffer read bursts all 60ms.
All 3 x 320 bytes are used for RTP packets, so samples are not lost
(only during the first 2 timeouts, but this is irrelevant).

And if you like logs ;), here are the behavior with 60ms in
portaudio.xml:

Strange timeout after 35...40ms, or should it be?

Betreff: Re: [Freeswitch-users] mod_portaudio send 3
rtppacket/60msinsteadof1 packet/20ms

I tried it with the latest trunk.
If I set it to 60ms sometimes I still get <1ms rtp packet delta, if I
set it to 120ms then there is none
The rtp packet delta is still random within 50-70ms with sometimes too
low 15-30ms, sometimes too high 100-150ms delta (with codec-ms = 60ms),
and with 15-20ms jitter.

	Have you tried setting the codec-ms in the portaudio.conf.xml to
60 or 120 ms?
	Maybe the soundcard is not able to do 20ms intervals and
portaudio is doing the least common multiple and chopping it up for us.
	I think what's happening is the timer in the module is set to
the interval from the config file (20ms) and during every 60ms period
there is no audio until the last ms.  so in each 60 ms:

	20ms (timeout..... flush buffer)
	20ms (timeout..... flush buffer)
	20ms (get 60ms worth of audio at once [3 20ms packets] but we
have already read 2 filler frames from the timeouts)

	So now we have read 5 packets instead of 3 and erased some of
our buffer because of perceived timeouts.
	The code is using the assumption that if the device will obey
the chosen frame size and sample rate requests down to the interval.

	If you find and edit conf/autoload_configs/portaudio.conf.xml

	look for this:

	 <param name="codec-ms" value="20"/>

	and change 20 to 60

	Setting this to 60 will change the frame size of all the packets
from 320 to 960 and set the timer to clock at an interval of 60ms
	Since the card seems to be able to reliably produce 3 20ms
packets every 60ms it should also be able to produce 1 60ms packet.

	FreeSWITCH should then buffer the audio and still deliver it
over SIP at 20ms if you want but you can opt to set the codec PCMU at 60i
to disable buffering if you are in a reliable network.

	The same should be true for setting the codec-ms to 120

		Hi Anthony,

		i also tested your patch with no success.
		As i already described below, the problem with all 60ms
3 packets comes from the soundcard.
		The hardware delivers its samples all 60 ms.
		Our problem is (like Csaba said) that we read out the
buffer after 60ms, 3 times, each with samples for 20ms, AND WITH NO
DELAY!
		So we get: 60ms wait and 3 RTP packets within <1ms to
send, and after that we already wait 60 ms for the next samples.

		In my patch i wait appr.20 ms if last method call was no
longer than 4ms ago,
		but i think we can do better with
switch_core_timer_check() method, but i don't know exactly how.

		You are absolutly right with your demand for a better
timing resolution under Windows,
		but this 60ms mystery is caused by the soundcard.
