I am getting video url of youtube from this API https://www.googleapis.com/youtube/v3/videos?id=ynMk2EwRi4Q&part=player&key=***************************.
But the problem is i am getting vimeo video which will give the message ‘This video contains content from VEVO.It is restricted from playback on certain sites.Watch on Youtube’.I download HCYoutubeParser-master where it will convert where it will play youtube videos.But it is unable to play Vimeo Videos.
This is my code:
mp1 = [[MPMoviePlayerController alloc]initWithContentURL:_urlToLoad];
[mp1 prepareToPlay];
self.mc3=mp1;
mp1.view.frame = self.view.bounds; //Set the size
[self.view addSubview:mp1.view]; //Show the view
[mp1 play]; //Start playing
AVAudioSession *session = [AVAudioSession sharedInstance];
NSError *setCategoryError = nil;
if (![session setCategory:AVAudioSessionCategoryPlayback
withOptions:AVAudioSessionCategoryOptionMixWithOthers
error:&setCategoryError]) {
// handle error
}

I am doing an iOS application with a video player in it. I have to change my video URL each time user switch it view angle. But when I am switching to a new URL my UI gets freezed for some time. Following is my code for switching video URL function.
// Create the AVPlayer using the playeritem
m_pMoviePlayer = [AVPlayer playerWithURL:[NSURL URLWithString:pUrl]];
NSError *_error = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: &_error];
m_pMoviePlayer.allowsExternalPlayback = NO;
// You can play/pause using the AVPlayer object
[m_pMoviePlayer play];
[self registerMoviePlayerObservers];
Thanks in advance.
I am using UIImagePickerController to record a video. and am using AVPlayer to play a video. and adding AVPlayerLayer to UIImagePickerController's cameraOverlayView so that i can see video while recording.
My requirement is
I need to watch video while recording video using UIImagePickerController
using headset i need to listen audio from playing video
need to record my voice to recording video
only my voice should be recorded but not playing video's audio.
every thing working but 4. audio from playing video also mix with my voice. how to handle this case? My final goal is
Out put for the playing video is headset
Input for the recording is headset's mic
Please help me to get this done.
Your requirement is interesting. So you need to play and record at the same time, right?
So that, you will need to initialize audio session with the category AVAudioSessionCategoryPlayAndRecord.
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
Because you are using UIImagePickerController to record so you don't have much control to your speaker and your mic. So test and see if it works.
In case you still have problem, I suggest you to use AVCaptureSession to record video without audio. Look at this example how to use it record-video-with-avcapturesession-2.
UPDATE: In my VOIP application, I use AVAudioUnit to record while playing back. So I think the only way is record video and audio separately and then use AVComposition to compose its to a single movie. Using AVCaptureSession to record video only and use EZAudio to record audio. The EZAudio use AVAudioUnit to record so that it should work. You can test it by record audio while playing a movie and see if it works. I hope it will help
UPDATE: I tested and it only work if you use headphone or select microphone back.
Here is the tested code:
NSString *moviePath = [[NSBundle mainBundle] pathForResource:#"videoviewdemo" ofType:#"mp4"];
NSURL *url = [NSURL fileURLWithPath:moviePath];
// You may find a test stream at <http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8>.
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];
AVPlayerLayer *layer = [[AVPlayerLayer alloc] init];
[layer setPlayer:player];
[layer setFrame:CGRectMake(0, 0, 100, 100)];
[self.view.layer addSublayer:layer];
[player play];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
//
// Setup the AVAudioSession. EZMicrophone will not work properly on iOS
// if you don't do this!
//
AVAudioSession *session = [AVAudioSession sharedInstance];
NSError *error;
[session setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
if (error)
{
NSLog(#"Error setting up audio session category: %#", error.localizedDescription);
}
[session setActive:YES error:&error];
if (error)
{
NSLog(#"Error setting up audio session active: %#", error.localizedDescription);
}
//
// Customizing the audio plot's look

self.audioPlot.backgroundColor = [UIColor colorWithRed:0.984 green:0.471 blue:0.525 alpha:1.0];
// Waveform color
self.audioPlot.color = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0];

self.audioPlot.plotType = EZPlotTypeBuffer;

self.inputs = [EZAudioDevice inputDevices];

[self.microphone startFetchingAudio];

Take a look at PBJVision library. It allows you to record video while you are watching the preview, and at the end, you can do whatever you want with audio and video footage.
Our app records and plays (those) videos. But somehow some of the videos are played without sound.
If i copy the video files to the mac via iTunes it plays the videos with sound, so the videos do have sound.
I checked the videos with a tool (called GSpot) and they all have the same audio codec and bitrate.
I tried about everything i found on SO but some of the videos dont play audio and the code is always the same and the videos do have sound as on a mac you can hear it.
This is how i setup the player
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
NSError *setCategoryError = nil;
[audioSession setActive:YES error:&setCategoryError];
[audioSession setCategory:AVAudioSessionCategoryPlayback
error:&setCategoryError];
_mpviewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:moviepath]];
_mpviewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
_mpviewController.moviePlayer.controlStyle = MPMovieControlStyleNone;
[_mpviewController.moviePlayer setScalingMode:MPMovieScalingModeAspectFill];
_mpviewController.moviePlayer.shouldAutoplay = YES;
[_mpviewController.moviePlayer prepareToPlay];
_mpviewController.view.frame = CGRectMake(0, 0, _screenWidth, _screenHeight);
[self addSubview:_mpviewController.view];
some time later, on a button press, it starts playing.
The record settings
[_session beginConfiguration];
[_session setSessionPreset: AVCaptureSessionPreset640x480];
AVCaptureDevice * videoDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
BOOL lock = [videoDevice lockForConfiguration:&error];
if(lock) videoDevice.focusMode = AVCaptureFocusModeContinuousAutoFocus;
[videoDevice unlockForConfiguration];
if(videoDevice == nil){
assert(0);
}
AVCaptureDeviceInput *input = [AVCaptureDeviceInput deviceInputWithDevice:videoDevice error:&error];
if(error){
assert(0);
}
[_session addInput:input];
AVCaptureDevice *audioDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeAudio];
AVCaptureDeviceInput * audioInput = [AVCaptureDeviceInput deviceInputWithDevice:audioDevice error:nil];
if(audioInput != nil) {
[_session addInput:audioInput];
}
[_session commitConfiguration];
I dont know if it is related but the audio seems to not play on videos that had a different view overlayed during the recording. It is possible to overlay a fullscreen view over the video preview while recording and it records fine and the file itself has audio and they play fine on a pc/mac... only on the device within our app those videos (again, not sure if related) have no audio. App uses same code for every video, so i can rename them, swap them etc, the behaviour has something to do with the audio channel of the video.
edit
Additional observation:
The vids where there is no sound, quicktime (only on mac) also plays no audio. QT on windows does play audio and all other players on windows do play audio as well.
Somehow the phone corrupts its own recording so that afterwards it doesnt recognize the audio channel it just recorded
edit 2
iPhone 6, iOS 8.1beta 2 -> as described
iPhone 4S, iOS 7.1.2 -> NO issue
iPad mini, iOS 8.0.2 -> always has the issue, not one videos audio channel can be read, but always exists and windows can play audio
I want to wrap this up.
The file was saved as ".mp4" and this causes the sporadic error.
Saving the file as ".mov" works. Same codec etc but without errors.
NSString *path = [[documentsDirectoryPath stringByAppendingPathComponent:
[NSString stringWithFormat:#"/%#", name]] stringByAppendingString:#".mov"];
outputURL = [[NSURL alloc] initFileURLWithPath:path];
[mAVCaptureMovieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self];
So I have this app where I play videos and when you exit the app I would like the user to continue to listen to the audio of the video. I use MPMoviePlayerController to play the video and it works in the app perfectly fine. I also setup AVAudioSession up before I play the video and I get no error.
NSError *audioSessionError;
NSError *activationError;
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback error:&audioSessionError];
[audioSession setActive:YES error:&activationError];
I also set in plist background modes audio. But the video with the audio both stop playing when you close the app. I've also imported the AVFoundation framework.
Simply set Application does not run in background to NO in .plsit file
You need to make couple of changes in plist file.i.e.
1) Set Required background mode to App plays audio
2) set Application does not run in background to YES.
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
Then, you need to write these much code in AppDelegate
Now, you can easily run audio while phone screen locks or goes in background.
This code worked for me, first you must to give your app permissions to keep playing music in the background (In your .plis), after that go to the wished class and implement this code, first the imports and the the method to play the music.
#import <MediaPlayer/MPNowPlayingInfoCenter.h>
#import <MediaPlayer/MPMediaItem.h>
#import <AVFoundation/AVFoundation.h>
---- o ----
-(void) playMusic{
[[AVAudioSession sharedInstance] setDelegate: self];
NSError *myErr;
// Initialize the AVAudioSession here.
if (![[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&myErr]) {
// Handle the error here.
NSLog(#"Audio Session error %#, %#", myErr, [myErr userInfo]);
}else{
// Since there were no errors initializing the session, we'll allow begin receiving remote control events
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
}
//initialize our audio player
audioPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:#"http://www.cocoanetics.com/files/Cocoanetics_031.mp3"]];
[audioPlayer setShouldAutoplay:NO];
[audioPlayer setControlStyle: MPMovieControlStyleEmbedded];
audioPlayer.view.hidden = YES;
[audioPlayer prepareToPlay];
[audioPlayer play];
}//end playmusic
You need to turn on Background Modes in capabilities.
In Info.plist I added:
<key>UIBackgroundModes</key>
<array>
<string>audio</string>
<string>location</string>
</array>
...
I load the sound like this:
NSURL *urlFail = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/criticalSound.wav", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:urlFail error:&error];
[audioPlayer setDelegate:self];
audioPlayer.numberOfLoops = 0;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
[audioPlayer setVolume:1.0];
if (audioPlayer == nil){
}else{
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
musicPlayer = [MPMusicPlayerController iPodMusicPlayer];
if (musicPlayer.playbackState == MPMusicPlaybackStatePlaying)
{
self.wasMusicAppOn = YES;
[musicPlayer pause];
}else{
self.wasMusicAppOn = NO;
}
[audioPlayer play];
}
This works fine when app is active.
But I have a location update when application is in background and from time to time (like when user pass 500m) I should play this sound.
So I put this code there.
Anyway problem is that sound plays when app is in foreground but doesn't work when it is in background.
What am I doing wrong here?
As far as I've been able to tell, you must actually be playing sound while going into the background to be able to continue playing sound in the background.
Also, the description for AVAudioSessionCategoryAmbient states that "Your audio is silenced by screen locking and by the Silent switch (called the Ring/Silent switch on iPhone)".
You need to make couple of changes in plist file.
1) Set Required background mode to App plays audio
2) set Application does not run in background to YES.
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
Then, you need to write these much code in AppDelegate
Now, you can easily run audio while phone screen locks or in background.
It works fine for me. :)
