you need to recompress the video as the current compression is incorrect:
H.264 Main Profile Level 4.0 video
here is a guidance form Apple:
H.264 Baseline Profile Level 3.0 video, up to 640 x 480 at 30 fps. (The Baseline profile does not support B frames.)
MPEG-4 Part 2 video (Simple Profile)
the audio might need to be changed according to:
(...) this class supports AAC-LC audio at up to 48 kHz, and MP3 (MPEG-1 Audio Layer 3) up to 48 kHz, stereo audio.
for MPMoviePlayerController (Class Reference in Apple's Documentation).
You should use AVPlayer and AVPlayerViewController instead. Follow this simple guide in order to play videos natively in your app:

In our iOS app, we will receive flv**(Container)** file having video and audio streaming something like this
Input #0, flv, from 'test.flv':
Metadata:
streamName : flvLiveStream
encoder : Lavf55.12.100
Duration: 00:00:48.00, start: 66064.401000, bitrate: 632 kb/s
Stream #0:0, 41, 1/1000: **Video: h264 (Baseline)**, 1 reference frame, yuv420p(progressive, left), 1280x720, 0/1, 15 fps, 1k tbr, 1k tbn
Stream #0:1, 14, 1/1000: **Audio: pcm_alaw,** 8000 Hz, mono, s16, 64 kb/s
and this needs to be converted to mp4 container and format as well, I am trying using ffmpeg, I believe thats only the way , using transcoding.c file but failed at this stage
Impossible to convert between the formats supported by the filter 'in' and the filter 'auto_scaler_0'
I am trying to learn from OSX command like ffmpeg -I test.flv test.mp4 ,
is that feasible to port to iOS
will it work in all different scenarios,
In Summary
--- What is the best possible way to convert flv to mp4 on the iOS device
where video will be in h264 and audio will be in swf codec ?

I have Array of words which i want to pick one after the other and play using AVAudioPlayer, how can i achieve playing NSString using AVAudioPlayer?
I don't have the audio file and i have list of words to which i want to play each word using AVAudioPlayer programming .
i found to play the audio file using AVAudioPlayer but not able to find to play NSSting or word in AVAudioPlayer
Below is the code using to play the audio clips :
NSString *path = [NSString stringWithFormat:#"%#/audio.mp3", [[NSBundle mainBundle] resourcePath]];
NSURL *soundUrl = [NSURL fileURLWithPath:path];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
You need to create an AVSpeechUtterance object using the words that you want the device to "speak," and then pass that object to AVSpeechSynthesizer. Those classes provide the methods you need to control the speech; there's no need to use AVAudioPlayer.
I am trying to play my audio file, which is 1.9 seconds, in my iOS App with these lines of code:
NSString *path = [[NSBundle mainBundle] pathForResource:#"bell" ofType:#"wav"];
NSURL *pathURL = [NSURL fileURLWithPath : path];
SystemSoundID audioEffect;
AudioServicesCreateSystemSoundID((__bridge CFURLRef) pathURL, &audioEffect);
AudioServicesPlaySystemSound(audioEffect);
AudioServicesDisposeSystemSoundID(audioEffect);
The audio file never plays but the code gets called.
EDIT: file bell.wav
bell.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 48000 Hz
The problem is that you are disposing the sound before it has a chance to start playing.
My book teaches you how to do this. Here is the code I provide in my book:
void SoundFinished (SystemSoundID snd, void* context) {
// NSLog(#"finished!");
AudioServicesRemoveSystemSoundCompletion(snd);
AudioServicesDisposeSystemSoundID(snd);
}
- (IBAction)doButton:(id)sender {
NSURL* sndurl = [[NSBundle mainBundle] URLForResource:#"test" withExtension:#"aif"];
SystemSoundID snd;
AudioServicesCreateSystemSoundID((__bridge CFURLRef)sndurl, &snd);
AudioServicesAddSystemSoundCompletion(snd, nil, nil, SoundFinished, nil);
AudioServicesPlaySystemSound(snd);
}
You can adapt that to use your sound and to trigger the playing in the way you need.
However, do note that you should not be using a 1.9 second sound as a system sound. It is much better to use an AVAudioPlayer (which my book also teaches you to do).
I used MPMoviePlayerController in my application.
I got the right URL but MPMoviePlayer does not play video it shows only black screen.
My code is as below:
[video setImage:[UIImage imageNamed:#"video_active.png"] forState:UIControlStateNormal];
NSString *filename=[NSString stringWithFormat:#"%#.mp4",[appdel.TempVideoUrl valueForKey:tag]];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:filename];
NSURL *movieURL = [NSURL fileURLWithPath:filePath] ;
theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.view.frame = CGRectMake(106, 18, 216, 235);
[uploadview addSubview:theMovie.view];
// Play the movie.
[theMovie pause];
I got the URL like this:
file://localhost/var/mobile/Applications/6E1D4CB7-A08D-438B-9FE7-E2FD9B7B5EEC/Documents/136_1355227629.mp4
Add [theMovie prepareToPlay]; before calling [theMovie play];.
prepareToPlay
Prepares a movie player for playback. (required)
- (void)prepareToPlay
Discussion
If a movie player is not already prepared to play when you call the
play method, that method automatically calls this method. However, to
minimize playback delay, call this method before you call play.
Calling this method may interrupt the movie player’s audio session.
For information on interruptions and how to resond to them, see Audio
Session Programming Guide. Availability
Available in iOS 3.2 and later.
Declared In MPMediaPlayback.h
Also you can use isPreparedToPlay for checking whether a movie player is ready to play.
Please refer this link for more.
Desperated.
Hello everybody!
I am having some issues with MPMoviePlayerController.
I've made it working with videos from NSBundle. But that's not what I need. I need to play it from Documents directory, because that is the place I store the recorded videos, wich URLs are stored in CoreData. but lets leave this aside, and simplify the code to its minimum needed. This code actually WORKS if using the contentURL, wich leads to NSBundle. After it, what I do to get to the docs place.
What I do:
NSURL *contentURL = [[NSBundle mainBundle] URLForResource:#"Oct_08_2012_10_00_51" withExtension:#"mp4"]; // this works
NSString* docPath = [NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString * docaPathFull = [NSString stringWithFormat:#"%#%#", docPath, #"/Oct_08_2012_10_00_51.mp4"];
NSURL * docUrl= [NSURL URLWithString: docaPathFull];
BOOL ex = [[NSFileManager defaultManager] fileExistsAtPath:docaPathFull];
NSLog(#"file exists: %d, path using docPath: %#",ex, docaPathFull);
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:docUrl];
player.shouldAutoplay = YES;
player.controlStyle = MPMovieControlStyleEmbedded;
[player.view setFrame: self.thumbButton.bounds];
[player prepareToPlay];
[self.view addSubview: player.view];
[player play];
What we have:
2012-10-08 13:14:43.532 Voto[11968:907] file exists: 1, path using docPath: /var/mobile/Applications/07B8574A-A3BA-4B23-BB3F-995B33A01B95/Documents/Oct_08_2012_10_00_51.mp4

So, the file exists...
Questions i've looked through:
MPMoviePlayer load and play movie saved in app documents
MPMoviePlayerController does not work with movie in documents folder
MPMoviePlayerViewController play movie from Documents directory - objective-c
I also checked ut with class reference, nothing specific about playing from Documents.
My projects settings:
using latest iOS 6,
Deployment target 5.0
Testing on both iOS6 iPhone simulator and an iPad with iOS 6.
If i forgot to add something, please remind me, I will do it immediately.
Please, help! :)
Well you'r not building the file URL the correct way, you should do it like this:
NSString *docPath = [NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *docaPathFull = [docPath stringByAppendingPathComponent:#"/Oct_08_2012_10_00_51.mp4"];
NSURL *docUrl= [NSURL fileURLWithPath:docaPathFull];
You should add directories and file to a path with the stringByAppendingPathComponent method of NSString;
Also when creating the file URL use fileURLWithPath: on NSURL, this willl create a correct NSURL for the giving path.
The most common mistake that everyone do is all use
NSURL *fileURL = [NSURL URLWithString:mVidPath];
^^^^^^^^^^^^^
instead of
NSURL *fileURL = [NSURL fileURLWithPath:mVidPath];
^^^^^^^^^^^^^^^
-(IBAction)playVideo
{
NSURL *vedioURL;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(#"files array %#", filePathsArray);
NSString *fullpath;
for ( NSString *apath in filePathsArray )
{
fullpath = [documentsDirectory stringByAppendingPathComponent:apath];
vedioURL =[NSURL fileURLWithPath:fullpath];
}
NSLog(#"vurl %#",vedioURL);
MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:vedioURL];
[player.view setFrame: self.view.bounds];
[player.moviePlayer prepareToPlay];
[self.view addSubview:player.view];
player.moviePlayer.controlStyle = MPMovieControlStyleDefault;
player.moviePlayer.shouldAutoplay = YES;
[player.moviePlayer setFullscreen:YES animated:YES];
[player.moviePlayer play];
[self presentMoviePlayerViewControllerAnimated: player];
}
Don't forget to add MediaPlayer.framework and
#import < MediaPlayer/MediaPlayer.h>
in your respective code.
Good Luck!!!
