Re: pjsip Digest, Vol 122, Issue 19

[dave <dave.anderson@xxxxxxxxx>]

I did a few things.

One is i hacked the callback for disconnect and put a pjsua->destroy() there.  That worked but gave ugly errors when it quit.

I have since found a better way is to open the thing in a linux screen and use perl's open3 to interact with it. It is a bit complex to have perl run a screen and then interact with the ui, but it works.

the only way to "fully kill PJSIP library" is to do something similar to System.unloadLibrary("pjsua2");

But since there is no such call, the closest thing you can do is make a PendingIntent to restart your app; restarting the app will clear out it's stack/memory and cause all libraries to be unloaded and loaded again when the application starts.

However, I didn't notice that PJSIP requires such hacks until now / yet. Only had such problems with Doubango.

Hi,


I successfully enabled video in Android by following the steps in given link,

https://trac.pjsip.org/repos/wiki/Getting-Started/Android


But my application is not displaying the video layout, from my observation i figured out that for media type video(index) i was getting

Call media status as  PJSUA_CALL_MEDIA_NONE and

VideoIncomingWindowId == -1(Invalid)

Message-ID: <58549f07be95487395d7484f5cee1d50@xxxxxxxxxx>
Content-Type: text/plain; charset="utf-8"

Hello,  I&#39;d like to know how to fully kill PJSipLibrary. I&#39;ve got Android application, and sometimes my pjSip library enters some strange error state - PJSIP_SC_SERVICE_UNAVAILABLE. The only thing that helps is to kill application, and start it from beginning.  When I do endpoint.libDestroy() it doesn&#39;t help. Is there any other way I could reset my pjSip    greetings  Andrzej
