Pjlib on Symbian, codec selection

[george.evi@xxxxxxxxx (George Evi)]

Hi,

 

Using one codec, application crashes.

For example I want to use only iLBC codec and I have deactivated (put in
comments "PJMEDIA_HAS_SPEEX_CODEC"," PJMEDIA_HAS_GSM_CODEC" .,) all the
other codecs.

My goal was to use a more performant codec as PCMU. 

 

When running (on Nokia E61) the application crashes.

 

I debug the application with Carbide v1.3 and I have now the call stack when
the program has crashed:

            Thread [Thread id: 616] (Suspended: Signal 'Exception 0'

As we can see it crashes inside the iLBC_encode() function.

 

Did anybody have this problem before?

 

Thanks,

George.
