[Freeswitch-users] mod_portaudio send 3rtppacket/60msinsteadof1packet/20ms

Fri May 9 04:34:56 PDT 2008

ok,
now it looks better, i. e. the switch_core_timer_check() times the
ReadAudioStream function,
but not perfect, now i see packets with differences of 15, 30, 45, 0 ms,

e. g. 15, 15, 30, 15, 15, 15, 31, 16, 15, 31, 15, 16, 16, 29 ms and so
on

Looks like we already stuck with time resolution, but the
switch_yield(1000) in ReadAudioStream() seems to work properly, strange
...
I don't have the time to go deeper into and i next read my emails on
tuesday :(

I don't want to hijack this thread from Csaba, should we make a jira
entry, Csaba? (for Anthonys clients sake :) )

r8305 is now exclusively using the timer to clock the audio stream.
This is silly because you would think the darn sound card could at least
provide timing at a lousy 8khz.

please tell me this fixes it..... if the thread gets any bigger my
client will crash.....

	i tested with 8296 now in all combinations, but allways the same
as before, 3 RTP packets all 60ms:
	now 2 frames accumulated (1 frame = 320 bytes always readable),
but switch_core_timer_sync() is not waiting 20ms.
	I think its because at the beginning we get late by 2 frames, as
you described (2 timeouts at the beginning), so
	the timer is lag behind the buffer.

	there the log for 20ms in portaudio.xml and vars.xml:

	ok,
	please try 8295 at all combinations of codec-ms etc.
	I changed the code to snoop the ringbuffer and make sure 2
frames worth of audio as accumulated before i read from it.

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

		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?

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.
