After I update pjsip from v2.6 to v2.7.1,my app will assertion failed with fuction pjsua_set_snd_dev(). According pjsip's ticket #1941:
To make outgoing call:
func provider(_ provider: CXProvider, perform action: CXStartCallAction) {
/* 1. We must not start call audio here, and can only do so
* once the audio session has been activated by the system
* after having its priority elevated. So, make sure that the sound
* device is closed at this point.
*/
/* 2. Provide your own implementation to configure
* the audio session here.
*/
configureAudioSession()
/* 3. Make call with pjsua_call_make_call().
* Then use pjsua's on_call_state() callback to report significant
* events in the call's lifecycle, by calling iOS API
* CXProvider.reportOutgoingCall(with: startedConnectingAt:) and
* CXProvider.reportOutgoingCall(with: ConnectedAt:)
*/
/* 4. If step (3) above returns PJ_SUCCESS, call action.fulfill(),
* otherwise call action.fail().
*/
}
To handle incoming call:
func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
/* 1. We must not start call audio here, and can only do so
* once the audio session has been activated by the system
* after having its priority elevated. So, make sure that the sound
* device is closed at this point.
*/
/* 2. Provide your own implementation to configure
* the audio session here.
*/
configureAudioSession()
/* 3. Answer the call with pjsua_call_answer().
*/
/* 4. If step (3) above returns PJ_SUCCESS, call action.fulfill(),
* otherwise call action.fail().
*/
}
To start sound device:
func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) {
/* Start call audio media, now that the audio session has been
* activated after having its priority boosted.
*
* Call pjsua API pjsua_set_snd_dev() here.
*/
}
When calling pjsua API pjsua_set_snd_dev(),there show:
Assertion failed: (param && id!=PJMEDIA_AUD_INVALID_DEV), function pjmedia_aud_dev_default_param, file ../src/pjmedia/audiodev.c, line 487.
I found that v2.7.1, in pjsua_set_no_snd_dev(),there is
pjsua_var.cap_dev = PJSUA_SND_NO_DEV; pjsua_var.play_dev = PJSUA_SND_NO_DEV;
but in v2.6 ,do not have this.
PJSUA_SND_NO_DEV and PJMEDIA_AUD_INVALID_DEV are same as -3.
Is this a bug,or I confuse anything?
