I am new to iphone development,I am parsing a XML URL and display its content in the table, when i click a row , its corresponding parsed tube URL is played using the movie player.I am using media player framework.Here is my code
NSURL *movieURL = [NSURL URLWithString:requiredTubeUrl];
if (movieURL)
{
if ([movieURL scheme])
{
MoviePlayerController *myMovie = [[MoviePlayerController alloc]init];
[myMovie initAndPlayMovie:movieURL];
}
}
This is working fine, but i want to play the video using "HTTP Live Streaming".How can i do that? Any tutorials and sample code would me more helpful.Thanks.
Apple provides and overview and some sample pages with streams. You provide the playlist file (.M3U8) URL to your MPMoviePlayer instance. If your server is set up properly, the .M3U8 file URL should suffice.
http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/StreamingMediaGuide/Introduction/Introduction.html#//apple_ref/doc/uid/TP40008332-CH1-DontLinkElementID_29
To implement in for the browser, which applies for a lot to native app development since it directs iphone users to movie app. A lot depends on the proper stream you're wanting to view http://www.ioncannon.net/programming/452/iphone-http-streaming-with-ffmpeg-and-an-open-source-segmenter/
Use MPMoviePlayerController for streaming from server.
-(void)initAndPlayMovie:(NSURL *)movieURL
{
// Initialize a movie player object with the specified URL
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
if (mp)
{
[self.moviePlayer play];
}
}

I have a remote mp3 (small file, just a few seconds) which I have the URL.
I need to play it on an App that uses iOS 4.
The URL is not exactly a .mp3 file, but it is a dynamic .php url that requests the .mp3 file. If I put that php route in the browser it downloads the mp3 file.
I am trying to use this project (https://github.com/mattgallagher/AudioStreamer) but it isn't working. The audio starts but it only plays a part of it.
How can I do it?
If it's truly just a small (and static, non-streaming) mp3 file, why not consider doing something like:
NSError * error = nil;
AVAudioPlayer * avPlayerObject =
[[AVAudioPlayer alloc] initWithContentsOfURL: yourRemoteURL error:&error];
if(avPlayerObject)
{
[avPlayerObject play];
}
Check out Apple's AVAudioPlayer class (documentation linked for you).
our client's video archive is hosted on vimeo, so I want to know if it is possible to use vimeo videos inside of iOS app so that user could press button and get fullscreen video playing in default video player. Is there any kind of API available for that?
upd: I know that in 2010 there was same question on SO, but maybe things changed during last year.
Get the video id, and load it into a webview using the vimeo player url. It will open the quicktime player in full screen mode on tap of the play button.
urlAddress = [NSString stringWithFormat:#"http://player.vimeo.com/video/%#",videoID];
NSURL *url = [NSURL URLWithString:urlAddress];
self.requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
You can use YTVimeoExtractor to extract the mp4 url that is usable in MPMoviePlayerViewController.
In order to load a sound file, I have the following code in my application :
- (id) init:(NSString*)a_filename ext:(NSString*)a_ext
{
...
NSString *t_soundFilePath = [CFileLoader getPathForResource:filename WithExtension:ext];
NSURL *t_fileURL = [[[NSURL alloc] initFileURLWithPath: t_soundFilePath] autorelease];
player = [[AVAudioPlayer alloc] initWithContentsOfURL: t_fileURL error: nil];
[player prepareToPlay];
...
}
All the sounds that I load are in my bundle, so I would like to know if the method "initwithcontentsofurl" stream the sound file or if all the file is cached.
I have a lot of sprites in my app so I want to minimize memory space used for sounds.
thx for your help
I used AVPlayer (not AVAudioPlayer) to stream background audio.
Sounds that are played using the AVAudioPlayer are streamed real time from storage. The drawback being that you can occasionally notice a small lag when it is due to start up. If you use OpenAL the sounds are loaded entirely into memory.
There's a good discussion of this sort of thing in the ObjectAL documentation - a library that is meant to simplify the playing of sounds and effects on the iPhone.
If you want to stream audio in your app you can use the following player instead of using AVAudioPlayer
https://github.com/mattgallagher/AudioStreamer
For this player you don't need to put sound files in your bundle, you can put them at server and use url to stream audio.
Hope, this wil help you.
" The AVAudioPlayer class does not provide support for streaming audio
based on HTTP URL's. The URL used with initWithContentsOfURL: must be
a File URL (file://). That is, a local path".
https://developer.apple.com/library/ios/qa/qa1634/_index.html
But you can work around - for example write asynchronously to local file, and init AVAudioPlayer with this file URL, it will work.
I need to play some audio streaming contents on iPhone, but there are some options and problems I can't solve:
1. http://cocoawithlove.com/2009/06/revisiting-old-post-streaming-and.html
It is a library provided by Matt Gallagher, but I saw the Limited scope, and I would play
a single song, not a radio station.
2. Suggestion from zonble
NSURL *URL = [NSURL URLWithString:#"http://zonble.net/MIDI/orz.mp3"];
NSData *data = [NSData dataWithContentsOfURL:URL];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:data error:nil];
But I need streaming for each "single song".
3. Using MPMoviePlayerController to wrapper.
Since the Class update new method, and
#interface MyAudioStreamer : UIViewController {
MPMoviePlayerController *mp ;
}
instead of [self addSubview:mp.view] I use my own xib file to implement play and
stop methods, but in this case, I have no idea to implement seekForward or seekBackward.
Is there any good idea to do AudioStreamer?
==== Update ====
after google 'AVPlayer' ,i used 3. Using MPMoviePlayerController to wrapper. to implement a auidoStreamer-like player ,there is something to share :
1.'playbackDidFinished' state
there're 2 conditions : a song did finished and play next song or a song interrupt by user press stop or exception, i used enum to filter my state.
2 multi-task playing your song in background
reference from https:// devforums.apple.com/message/264397
and if iOS SDK update, the solution might be changed because method would be diplicated. so i suggest to read library provided by Matt Gallagher.
anyone who konws when the library have no codec match download item (for example, my item encode by .AAC 128-bit and the library not support or at most .AAC 64-bit), what happen would the player be ?
You can either parse the icy meta data yourself, or if you're using iOS 4.0 you can playback using an AVPlayer and observe the timed metadata to discover the song boundaries and titles.
How can I play video files in my application from an iPod video library? Is there any other possibility to search and play video files stored anywhere in an iPhone?
You can't The iPod Library access is audio only at this time. There is currently no way to access any video outside of your application sandbox (in other words, you can only search through and play video your app has downloaded itself).
If you need access to the video library you should file a bug with Apple describing why you need it.
You can play video files store in device, there are 3 places you can search :
Camera Roll : video recorded
iPod Library
File Sharing
After searching on internet I found this sample of Apple describe how to get and play those videos.
Here is AVPlayerDemo
Hope this will help you. Good luck :)
MPMediaPropertyPredicate *predicate = [MPMediaPropertyPredicate predicateWithValue:[NSNumber numberWithInteger:MPMediaTypeMovie] forProperty:MPMediaItemPropertyMediaType];
MPMediaQuery *query = [[MPMediaQuery alloc] init];
[query addFilterPredicate:predicate];
NSArray *items = [query items];
NSURL url = [[NSURL alloc]init];
for (MPMediaItem item in items)
{
//get the Title of video
NSString* title = [item valueForProperty:MPMediaItemPropertyTitle];
NSLog(#"title %#",title);
//get the path of Video
url = [item valueForProperty:MPMediaItemPropertyAssetURL];
NSLog(#"url %#",url);
}
