I need to play audio sound from the main speaker of the iPhone while the user is recording a video. Is it possible? How can i do?
I need the sound is being played from the main speaker so in that way I can record this sound in my video.
Have a look at this answer!
He was already using video and sound the way you want, except the routing was wrong... An answer there has a code snipped that should do the trick.
Yes you can do it by setting AVAudioSession class property and using AVAudioPlayer to play sound
Set AVAudioSession category property to AVAudioSessionCategoryPlayAndRecord and also set its category options to AVAudioSessionCategoryOptionDefaultToSpeaker|AVAudioSessionCategoryOptionMixWithOthers this will solve the problem. Please check the below set of code
#property (strong, nonatomic) AVAudioPlayer *audioPlayer;
NSURL *soundUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"VoicemailSound" ofType:#"mp3"]]; //Download and add a system sound to your project and mention its name and type here
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionDefaultToSpeaker|AVAudioSessionCategoryOptionMixWithOthers error: nil];
[self.audioPlayer prepareToPlay];
[self.audioPlayer play];

I am streaming music file using AVAudioPlayer, It plays fine in background if i use nib file but when i try the same code using storyboard, The music playing stoped. I can't understand the reason why its stop playing in background when i using storyboard.
i am using this code for it
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[audioPlayer setVolume:0.1];
[audioPlayer play];
Can any help me to play it in background using storyboard. Thanks in advance.
Let's try:
#implementation YourViewController
{
AVAudioPlayer *audioPlayer;
}
// if your are using ARC, after exiting this method, system will kill your audioPlayer. This is the reason why you can not play the music.
// in your method:
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
I've set my phone to muted state by switching vibrate/sound hardware button. In whole application some background music is playing unless the device is in muted state. So in this case, my music is playing but muted. Now in some point I want to present video (which is without sound but this shouldn't matter), however the video in MPMoviePlayerController turns music from AVAudioPlayer on even though the device is is 'muted' state. The AVAudioPlayer continues to play loudly even when i quit MPMoviePlayerController.
Some code samples, but i doubt it will help:
// movie without sound
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategorySoloAmbient error:nil];
NSURL *movieURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"myVideo" ofType:#"mp4"]];
_moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
[_scrollView addSubview:_moviePlayerController.view];
[_moviePlayerController prepareToPlay];
[_moviePlayerController play];
// music
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[_audioPlayer prepareToPlay];
[_audioPlayer play];
To fix this, I had to rewrite the code but instead of using MPMoviePlayerController I've used AVPlayer. Everything works like a charm now.
I am using AVAudioPlayer to make an MP3 player. I have multiple MP3 sounds and would like to play these sounds one by one. Following is the logic of my app:
///// For playing 1st sound
mp3Player = [[AVAudioPlayer alloc] initWithContentsOfURL:url1 error:nil];
[mp3Player prepareToPlay];
[mp3Player play];
///// For playing 2nd sound
mp3Player = nil;
mp3Player = [[AVAudioPlayer alloc] initWithContentsOfURL:url2 error:nil];
[mp3Player prepareToPlay];
[mp3Player play];
///// For playing 3rd sound
mp3Player = nil;
mp3Player = [[AVAudioPlayer alloc] initWithContentsOfURL:url3 error:nil];
[mp3Player prepareToPlay];
[mp3Player play];
etc...
Just would like to know: I nil out the player and alloc AVAudioPlayer before playing the next sound. Is there any performance (speed) or memory (leak) concern in this logic? (I am using ARC). If so, is there any way to alloc AVAudioPlayer just ONE time, and to accept diffrent URLs pointing to those sounds? Thanks a lot in advance.
I think below link may help you:
How to play multiple audio files in sequence by loop in AVAudioPlayer?
In which audioPlayerDidFinishPlaying is used to play next song after one finishes.
In a view controller I have a video playing and also some background music. If the background music is playing, the video freezes when it goes to loop. If the background music is not playing the video loops normally as it should.
Here's how I'm setting up the video player:
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[self getBundleClip:#"MyVideo"]];
self.moviePlayer.controlStyle = MPMovieControlStyleNone;
self.moviePlayer.shouldAutoplay = YES;
self.moviePlayer.repeatMode = MPMovieRepeatModeOne;
The audio is playing via this Sound Manager. Any idea why the video would be freezing?
Try to use play music in background AVAudioPlayer and play same time MPMoviePlayerController like below code for play the AVAudioplayer in repeat mode:
first initialize the AVAudioplayer object in your header file (.h) like below:
#interface Yourviewcontroller : UIViewController
{
//your some codes after
AVAudioPlayer *audioPlayer;
}
#property (strong, nonatomic) AVAudioPlayer *audioPlayer;
after implement play audio file in background like below code:
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:#"audio" ofType:#"mp3"]] error:NULL];
audioPlayer.numberOfLoops =-1;//it's play audio repeatedly
audioPlayer.currentTime=0.0f;
[audioPlayer prepareToPlay];
after play audio any part of project like below code:
[audioPlayer play];
you want stop the audio player like below code:
[audioPlayer stop];
I have a problem with the AVPlayer playing in background mode, like a lot of people here and everywhere on the web. I've done what I think is supposed to work, but is still doesn't... I think my problem might be where I set and use my AudioSession and AVPlayer.
1) The "audio" key is in UIBackgroundModes of my Info.plist
2) AudioSession set like this in AppDelegate (initialised in didFinishLaunchingWithOptions):
AVAudioSession *audio = [[AVAudioSession alloc]init];
[audio setCategory:AVAudioSessionCategoryPlayback error:nil];
[audio setActive:YES error:nil];
3) I use an AVPlayer (not AVAudioPlayer) also implemented in AppDelegate. (initialised in didFinishLaunchingWithOptions, after the AudioSession), right after the AudioSession
// Load the array with the sample file
NSString *urlAddress = #"http://mystreamadress.mp3";
//Create a URL object.
self.urlStream = [NSURL URLWithString:urlAddress];
self.player = [AVPlayer playerWithURL:urlStream];
//Starts playback
[player play];
And still, the audio is suspended everytime the app goes in background (when I press the "Home" button).
By the way, the problem was just with the simulator. Works fine on the iOS devices
