I am working on PJSIP. Two ways Video and Audio call are working fine but the issue is when app is in background and I made a new Incoming call, The callKit is showing new incoming call and I picked up the call. Then app moves from background to foreground but video is not showing and audio is working at that time. If I made a call in foreground then video is showing at both end.
Please find below the logs :

Add some delay in answering the call it will work as sometimes PJSIP is taking time to initiate the camera.

App is getting hang after accepting incoming video call with PJSIP.
I have already answered call with 180 (Ringing state) and then accept call with code 200 but at that time my app is getting hang

I have same problem with iOS platform. If you using pjsua_call_answer2, you could replace 180 (PJSIP_SC_RINGING) to 183 (PJSIP_SC_PROGRESS). It work fine with "out_auto_transmit = true"
I have used AVAudioPlayer and set the numberofloop to -1 because I want to play the audio in an infinite loop. At first it works well, but in the middle of playing sound track, I got the following error log continuously and my sound track was stopped.
2017-02-22 10:08:28.863041 TestBridgingHeader[1092:30476] [aqme] 255: AQDefaultDevice (173): skipping input stream 0 0 0x0
I am using two media players to get fade in fade out sound. I played these two media players using blocks:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{});
Why does my sound track stop and why does it show AQDefaultDevice error logs?
This is a bug in Xcode 8.
You can resolve it with these steps:
Select Product --> Scheme--> Edit Scheme.
Select Arguments.
Add OS_ACTIVITY_MODE setup "disable" to Environment Variables.
I'm developing an iOS app to play a RTSP Stream (with two tracks, one audio and one for video), and i'm using libVLC to do it.
Playing the video or only audio (adding the option "--no-video") works perfectly. If i start the player with only audio and then enter background the player keeps playing the stream.
The problem i'm having is that if i enter background when video is playing, i want to stop the video and start a new libVLC player with only audio. In that scenario i get this error message:
ERROR: [0x48e2000] >aurioc> 783: failed: '!int' (enable 2, outf< 2 ch, 48000 Hz, Float32, inter> inf< 2 ch, 0 Hz, Float32, non-inter>)

[1973b5e4] core audio output error: module not functional
[17a27e74] core decoder error: failed to create audio output
The code in my appDelegate:
- (void)applicationDidEnterBackground:(UIApplication *)application
{
NSLog(#"applicationDidEnterBackground");
if(_playerController!=NULL){
[_playerController performSelector:#selector(goToBackground) withObject:nil afterDelay:1];
_playerController=NULL;
}
}
And in my uiViewController:
-(void)close:(BOOL)enterBackground
{
[_mediaPlayer stop];
NSArray* options = #[[NSString stringWithFormat:#"--no-video"]];
_mediaPlayer = [[VLCMediaPlayer alloc] initWithOptions:options];
_mediaPlayer.delegate = self;
_mediaPlayer.drawable = _videoView;
_mediaPlayer.media = [VLCMedia mediaWithURL:[NSURL URLWithString:url]];
[_mediaPlayer play];
}
Am i doing anything wrong?
yes, don't stop the video and start a new player. Just disable video decoding on the existing player and re-enable it once your app is in the foreground again. This is way more efficient, elegant and faster. Additionally, you won't run into this audio session locking issue.
How is VLC for iOS doing this? When the app is on the way to the background, we store the current video track's ID, which can be "1" but also something entirely else depending on the played stream, in a variable next to the media player object. Then, we we switch the media player's video track to "-1", which is the value for "off" in any case. Video decoding stops. Once the app moves to the foreground again, the media player's video track is set to the cached track ID again and video decoding starts again.
I have a recording app. I'm running into a problem that when I open my app and the phone is paired to a bluetooth device, as soon as I start recording, the bluetooth device thinks I'm starting a phone call. It makes an outgoing call sound, and displays on the screen "ON CALL" (always talking about the BT device), but no actual call is being made of course.
This is how I'm currently initializing my session:
[[AVAudioSession sharedInstance] overrideOutputAudioPort:AVAudioSessionPortOverrideNone
error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord
withOptions:AVAudioSessionCategoryOptionMixWithOthers |
AVAudioSessionCategoryOptionAllowBluetooth
error: nil];
I tried it on 2 different bluetooth devices and similar outcomes happen on the same. Both try to establish a phone call.
After looking at BlueTooth logs, I found some clue as to what it is doing:

What is that Setting up virtual call??? The only thing I'm doing in code at that point is
[self.audioRecorder record];
self.audioRecorder is an instance of AVAudioRecorder of course.
How can I prevent this?
Change your AVAudioSession options whenever you want to start recording and do not allow Bluetooth:
[[AVAudioSession sharedInstance] overrideOutputAudioPort:AVAudioSessionPortOverrideNone
error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord
withOptions:AVAudioSessionCategoryOptionMixWithOthers
error: nil];
[self.audioRecorder record];
Once finished the recording, on the delegate call of the AVAudioRecorder instance:
- (void)audioRecorderDidFinishRecording:(AVAudioRecorder *)recorder successfully:(BOOL)flag
Set up back your AVAudioSession options to allow Bluetooth AVAudioSessionCategoryOptionAllowBluetooth this way the AVAudioSession will not assume the recording input should be handled as Voice Call from the connected BT device.
I had compiled the code from this link, also I am able to successfully register a account on sip server. But when I make a sip call then it gives a trap error in pjsua_call_media_init.
I need help to understand the reason for error mentioned below.
