In my app i am playing a video using the following code.
NSURL *myURL = [[NSURL alloc] initWithString:downloadURL];
mMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:myURL];
if (mMoviePlayer) {
[self initMoviePlayer];
[mMoviePlayer play];
}
This code is working fine in simulator, but when i test it in device it is giving "BAD_ACCESS" error. Device is not at all sending the request to video.
Can some one help me with this..
Thanks...
There's nothing wrong with this code. The bug is somewhere else.
BAD_ACCESS generally points to memory management issues: you're trying to access an object that has been deallocated. If you're sure that the crash is happening on the above line, double check that safeURL exists at that point. If it does, you're going to have to post more code for us to give you any pointers.

I have a problem with MPMoviePlayerController, i.e. I am playing the live stream url in (m3u8 format) MPMoviePlayer like below:
player = [[MPMoviePlayerController alloc] initWithContentURL:audioUrl];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(loadStateDidChange:)
name:MPMoviePlayerLoadStateDidChangeNotification
object:player];
if ([player respondsToSelector:#selector(loadState)])
{
// Set movie player layout
[player setMovieSourceType:MPMovieSourceTypeStreaming];
[player setControlStyle:MPMovieControlModeVolumeOnly];
[player setFullscreen:YES];
[player prepareToPlay];
[player play];
}
}
It is working in both simulators & iPad device with ios 5 version, but it is not giving the audio in any iPhone device i have.
Please help me out...
Thanks, in advance.
mr simham ... check this below url it help for us becoZ
Call stream-url within mobile safari. If that has the same results, then your code is correct and the stream is not. It would be an incorrectly encoded audio stream then.
it depends on bandwidth also below ref url regards to bandwidth check it once.... u r ref Stream URL prepare,according to BandWith

You are assigning a deprecated MPMovieControlMode (MPMovieControlModeVolumeOnly) towards the controlStyle property which is expecting a MPMovieControlStyle.
Additionally, your code is missing the part that assigns the MPMoviePlayerController.view towards any superview and also its sizing is missing.
Last but I guess most importantly for you, I am guessing that the iPhone you are trying it with has set the volume all the way down to silence. Or, maybe the audio-routing is not set towards speaker-output. For the latter, make sure you are not setting up the audio session incorrectly anywhere else in your App. When in doubt, try fiddling with the useApplicationAudioSession property. Try setting it towards NO and see if that changes your results.
If all above fails, then one additional check would be to call the stream-url within mobile safari. If that has the same results, then your code is correct and the stream is not. It would be an incorrectly encoded audio stream then.
Check if your iPhone is on loudspeaker mode or not -
if not than set it using this-
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
Check if the iPhone is in silent mode. To play audio even in silent mode, add the following code in AppDelegate's application:didFinishLaunchingWithOptions:
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
i want to play a short video as soon as the application launches. It's a short video and a light application so i do not expect any serious delays. However my problem is that although my code works fine wheni test it as an IBAction, it doesn't work when i paste it anywhere else like ViewDidLoad, awakeFromNib, ApplicationDidFinishedLaunching. I am searching all day long for tutorials that work in Xcode 4.2 (ARC enabled) but i couldn't find anything that worked.
Here is my code:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"testmovie" ofType:#"mp4"]];
MPMoviePlayerViewController *playercontroller = [[MPMoviePlayerViewController alloc]
initWithContentURL:url];
[self presentMoviePlayerViewControllerAnimated:playercontroller];
playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
//playercontroller.movieControlMode=MPMovieControlModeHidden;
[playercontroller.moviePlayer play];
playercontroller = nil;
If anybody can provide a tutorial or sample code, i would be extremly grateful!
Thanks in advance.
take out movie player and just use
[playercontroller play];
if it needs releasing do so as well
I'm currently developing an ipad application that will play video from wowza streamiong server.
Plainly saying, I load video into UIWebView as follows:
NSURL *videoURL = [NSURL URLWithString:#"http://fishki.tv:1935/vod/mp4:20100731194117.mp4/playlist.m3u8"];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:videoURL];
UIWebView * WView = [[UIWebView alloc] init];
WView.frame = CGRectMake(0,0,300,200);
[self.view addSubview:WView];
[WView loadRequest:requestObj];
It plays video ok (you can try yourself), BUT when i try to load another video (or even the same one) by changing videoURL and calling loadRequest method again, it plays only sound without video.
I'm starting to think that it is a bug in ipad simulator because I was unable to fix it anyhow.
I would be glad to hear any suggestions because I also was unable to find similar problem on the web. Thanks in advance.
The web view behaves erratically on Simulator. Can you try the same on a regular device? I believe it might actually be working.
I initialize an AVAudioPlayer instance:
NSString* path = [[NSBundle mainBundle] pathForResource:#"foo" ofType:#"wav"];
AVAudioPlayer* player =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:nil]; //Returned object not nil, indicating that the file has loaded successfully
BOOL b = [player prepareToPlay]; //returns TRUE
BOOL b2 = [player play];
//returns TRUE, goes immediately to the next line since asynchronous
[NSThread sleepUntilDate:[NSDate dateWithTimeIntervalSinceNow:1]; //wait 1 sec
printf("%10.4f\n",player.duration); //duration is 2s
printf("%10.4f\n",player.currentTime); //position remains 0
/* There is no sound output, player is also stuck since position==0 */
Does anyone know why the AVAudioPlayer is not responding? Is there something that I am overlooking while initializing, playing the audioplayer? Boilerplate code maybe?
I am running this on the iPhone simulator. Also, AudioServicesPlaySystemSound() works for the same file, which is puzzling, but this indicates that sound playback might work with AVAudioPlayer as well.
I have 2 quick suggestions:
Check to see if that path actually gives you data. Alloc a NSData object using [[NSData alloc] initWithContentsOfFile:path] and inspect it in the debugger to see if you're actually loading that wav file.
I wrote a sample project that uses AVAudioPlayer here: AVAudioPlayer Example. As the code is pretty much the same as yours, the only thing I can imagine is that there is a problem with your data.
Check those out and see if it gets you anywhere!
I have just had a similar problem. I am not sure if it is the same solution, but my application records audio through the iphone and then plays it back to the user.
I thought I was doing the correct thing by telling my audio session that it was going to record data, so I did the following:
[audioSession setCategory:AVAudioSessionCategoryRecord error:nil];
Using this setting playback worked on the Simulator but not on the device.... the didFinishPlaying event never got raised.
I removed this line after realising I didn't need it an audio playback started working correctly. Now I just need to work out why it is so quiet :)

When I use my app (on the device), the actual volume works OK for a while, but after a few days it seems to get 'stuck' at a low level.
Adjusting the volume rocker has no effect - and it shows 'Ringer' text. I've noticed that other people's apps are similarly affected if they show the 'Ringer' text when adjusting the volume. But apps which don't show 'Ringer' text are not affected by this.
How would I remove the 'Ringer' text and get my app to respond properly to different volumes?
I found some code on Apple's forums which fixes it. You have to use the AVFoundation.framework and put a bit of code into your app delegate. And put an audio file called 'blank.aif' into your project. Basically, it's a hack which prepares a file to play, but then never plays it. This fools the system into thinking that sound is being played all the time, which allows the user to use the main volume control.
#import <AVFoundation/AVFoundation.h>
//...
-(void)applicationDidFinishLaunching:(UIApplication *)application {
//volume control hack
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"blanksound" ofType:#"aif"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
AVAudioPlayer *volumeHack = [[[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil]retain];
[fileURL release];
[volumeHack prepareToPlay];
// other applicationDidFinishLaunching stuff
}
