Re: UNDERRUN OVERRUN ISSUE

Christian Hoff <christian_hoff@xxxxxxx> · Tue, 28 Aug 2018 12:39:14 +0200



    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,
