baresip crash with speex codec about baresip HOT 9 CLOSED

hi, thank you for the detailed report

I am wondering if something is wrong with the libspeex for your platform,
perhaps it is built w/o the CTL interface? Are you able to reproduce the bug
on other platforms, such as Linux/OSX ?

I just tested latest baresip on OSX with libspeex 1.2rc1, no warnings and
audio working fine. Do you know which version of libspeex you are using?

this warning is certainly very worrysome:
warning: Unknown nb_ctl request: 12

are you able to insert some extra debug lines, to find out of the segfault
is in baresip code or libspeex code ?

hi, what is the ctl interface? i m also thinking something wrong with the
libspeex version on my platform. my version is "speex-1.2rc1" on openwrt OS.

libspeex has a configure option "--disable-vbr" which defines DISABLE_VBR for the source code.
the unknown CTL requests (SET_VBR, SET_VAD, ..) are inside one of these #ifndef DISABLE_VBR
blocks.

but that should not lead to a segfault, I think.

I just tried libspeex-1.2rc1 w/disable-vbr locally and I get the warnings but no crashes.

can you please try another audio-codec (such as g711.so) and see if that works?
can you also try to unload speex_aec.so and speex_pp.so and check if that makes a difference?

are you able to get a backtrace from your coredump?

from baresip.

g711 codec works fine. i tried with the speex aec and speex pp unloaded and
the problem disappears ( while using speex codec ) . so the problem is
likely in libspeexdsp ? i shall need the aec module in speex..i have the
microphone too close to speaker..and the other party talking to baresip
hears very loud echo.

i am going to check the core dump .

from baresip.

so it is either the speex_aec.so or speex_pp.so module that is crashing.
can you try to load only speex_aec.so and then only speex_pp.so to see which is
the culprit?

as noticed from your log, this debug line is never printed:

info("speex_aec: Speex AEC loaded: srate = %uHz\n", prm->srate);

so my guess is that the crash happens somewhere before that (in speex_aec.c)

from baresip.

hi,
sorry about getting back to you so late. Yes, the error is indeed in
speec_aec.c file. this is the output ( i have added some debugging msg in
between )

( the modified speex_aec.c file is attached here )

the program crashed when it calls:

i checked the speexdsp..its version 1.2rc1 ( latest ) . This works fine on
linux though..but not on the embedded platform ( openwrt on carambola2 ) .

do you think i am missing something during compilation ? any flags that
should be set..that i am forgetting ?

i am not very sure if you are familiar with openwrt platform's makefiles (
but i have seen you replying in openwrt forums ).

i have modified the baresip Makefile for openwrt like this:
http://pastebin.com/220N8ViX to make sure speex_aec and speex_cc compiles
when compiling baresip.

i have also reqeusted the same question here:
https://forum.openwrt.org/viewtopic.php?pid=248647#p248647

khan

from baresip.

this is most likely a bug in Speex AEC. not sure what we can do about it,
perhaps build speexdsp from scratch and debug the library.
Or find a better AEC algorithm that we can use.

closing the ticket for now

from baresip.

@alfredh
Hi, many versions after i have the same problem with segment fault AEC speex plugin, others plugin works very well, i using openWRT on MediaTek LinkIt Smart 7688, maybe if anyone can implement WebRTC AEC, this would be very useful.
