Hi Christian,
 
thanks for your reply. I am using omapl138 development board. it does not contain "sudo" and  "apt-get" package. I am doing cross compilation of pjsip for omapl138 board.
how can i solve the underrun/overrun issue?
 
Regards,
Allwyn

Hello Allwyn,

I think the reason why you get the compile errors for webrtc is that pjsip sometimes does not correctly detect which instruction set the CPU supports. It then tries to compile webrtc with x86 SSE instructions, even if you are on ARM or any other non-x86 platform. This causes compile errors. A workaround is described in Adam Rossi's guide for compiling pjsip for the Raspberry Pi here: https://github.com/acrossi/raspberry-pi-stuff/wiki/Compiling-PJSIP-with-Video-and-Audio-on-the-Raspberry-Pi-3---RPI-Camera-Module . Even if you are not using a Raspberry Pi, the workaround should still work for you (as long as you are on ARM platform).

Maybe the disabling of webrtc is also the reason why you don't hear audio. I cannot tell. In any case, the correct fix for your issue would be to not just disable webrtc, but to fix the compile errors. If you keep on fighting with compile problems, you can also post your compile errors to the list.

 

Best regards,

   Christian

Hi ,
 
I am new to pjsip. I am running pjsip(version 2.7.1) on embedded platform. I can not build pjsip with libwebrtc. So I disabled libwebrtc in configuration step.
Then it works on embedded platform. while making call it shows underrun ,overrun error, I can not hear audio in call.
 
The log of the pjsip application is following,
