Hello everyone,
I am trying to write a C++ application using pjsua2 that will run on the
Raspberry Pi (armv6 architecture). I used a cross compiler to compile
pjproject on my laptop (normal intel 64-bit architecture).
The initialisation of the endpoint and library go just fine, my test sip
account appears online to other accounts. But when I try to make a call,
nothing goes trough and I don't hear any sound. I expect that you should
hear a ring when trying to make a call, please correct me if I'm wrong.
So I suspect that it is a audiodevice problem.
In my C++ code I tried to play a normal .wav file, and that also fails.
The program seems to think that everything is fine, but I don't hear
anything. I checked if the program is using the right device and indeed
it is. When I try "./pjsua --play-file THEFILE.WAV" like found in the
sound-problem page of pjsip, I do hear the sound. So it has nothing to
do with the pjsip libraries, but something else.
So my device is definitly working properly, the pjsip executable is
working, so that are all not the problem. So next I will copy the
program output and the way I initialize pjsua and play the audiofile.
The device I am using is Logitech Wireless Headset: USB Audio and I am
compiling with the flags:
-DPJMEDIA_AUDIO_DEV_HAS_ALSA=1
-DPJMEDIA_AUDIO_DEV_HAS_PORTAUDIO=0
Any help/corrections will be greatly appreciated.
