audio / video live streaming

[Alexandre Viana]

hi guys,

i need make an app to live stream audio / video in iphone . how i can
make it with phonegap?
the stream is by http in an m3u8 playlist...

i tried some technics, but, without success:

1) for live audio, i used html 5 "<audio src>" tag, but, i can't use
autoplay (its essencial for an webradio app)

2) for live video, i tried html 5 "<video src>" tag, but, with this
tag, i can't use the orientation (the video always is displayed in
vertical)

3) for live video, i tried direct link to m3u8 using childbrowser,
but, this opens two windows: the childbrowser window and the quicktime
window (for quit, the user have to press "done" twice)


any suggestions?

[Giacomo Balli]

i open the link childbrowser. works like a charm

[Alexandre Viana]

It´s open ok, but, the user have to press "done" twice to back to application :(

video will always open and play full screen therefore the user has to
tap done at least once...

hi

the problem is not open the link..the problem is when the user need close the live streaming..he need press "done" to quit quicktime, then, press "done" again to close the childbrowser window.

[Giacomo Balli]

that's what I'm saying, on the iphone all videos will play fullscreen
in a quicktime window; therefore the user will have to click "Done" at
least once.

He only wants to press done once, the done of quicktime, but not the
done of childbrowser or similar

You can mod pgap so it plays any video direct in media player.
Negating need for childbrowser will post code later when im home

Sent from my iPhone

[Gabriel]

Wow really ?

I would very happy to read from it !
I'm waiting for your snippet, and I am sure, anybody would be interested.

Thanks !

[Gaby Desjardins]

So what about this code ?
How could I mod gap to play video in native?

Thanks !

Hi Gabriel

As mentioned earlier here is the code...however sorry but I forgot to mention this is a iPhone only solution. But I Hope is still of some use. Credit must go to Rich Thibault  and PanMan for this:) This basically checks if the url being accessed is a video file, if it is then it opens in the media player.

In your appdelegate.m file, at the top where the other imports are add: 

#import <MediaPlayer/MediaPlayer.h>

In your appdelegate.m file find the webview shouldStartLoadWithRequest method and change to the extended one below:

/**

 * Start Loading Request

 * This is where most of the magic happens... We take the request(s) and process the response.

 * From here we can re direct links and other protocalls to different internal methods.

 */

- (BOOL)webView:(UIWebView *)theWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType

{

/***  Credit goes to PanMan (Martijn Pannevis <mar...@panman.nl>) for this elegent hack 

Watch for video URLs and launch them in the media player.  No HTML5 video tag necessary, just a normal link.

***/

NSURL *url = [request URL];

if (![[url scheme] isEqualToString:@"gap"] && ([[[url path] pathExtension] isEqualToString:@"mp4" ] || [[[url path] pathExtension] isEqualToString:@"m4v" ] || [[[url path] pathExtension] isEqualToString:@"m3u8" ] || [[[url path] pathExtension] isEqualToString:@"mp3" ])) {

//video files are .mp4 or m4v, stream indexes are m3u8

//it's a movie, go play!

//NSLog([url]);

[self playMovieAtURL:url];

return NO;

} else {

return [ super webView:theWebView shouldStartLoadWithRequest:request navigationType:navigationType ];

}

}

-(void)playMovieAtURL:(NSURL*)theURL {

MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:theURL];

theMovie.scalingMode=MPMovieScalingModeAspectFit;

// Register for the playback finished notification.

[[NSNotificationCenter defaultCenter] addObserver:self

selector:@selector(myMovieFinishedCallback:)

name:MPMoviePlayerPlaybackDidFinishNotification

  object:theMovie];

// Movie playback is asynchronous, so this method returns immediately.

[theMovie play];

}

-(void)myMovieFinishedCallback:(NSNotification*)aNotification

{

MPMoviePlayerController* theMovie=[aNotification object];

[[NSNotificationCenter defaultCenter] removeObserver:self

name:MPMoviePlayerPlaybackDidFinishNotification

  object:theMovie];

[theMovie stop];

// Release the movie instance created in playMovieAtURL

//Bug fix for autoplay bug on 3.0

float version = [[[UIDevice currentDevice] systemVersion] floatValue];

if (version >= 3.0) {

// iPhone 3.0 code here

//    theMovie.initialPlaybackTime = -1.0; //Breaks on 2.x compiling

[theMovie setInitialPlaybackTime: -1.0]; //Only gives a warning on 2.x :)

}

[theMovie release];

NSLog(@"Go STOP received");

Hi !

Thank you for the idea, here what I get :

----- first click on the href pointing to mp4 content

Any idea or hints, your solution look good ! I really wish it would work.

Thank you

Hello all,

The plugin thing was due to plugin in my computer.

Nothing to worry about on the phone... 

Unfortunately, I still can not open the mediaplayer.

It did switch to a different thread :

[Switching to thread 13059]

[Switching to thread 14083]

It did switch to a different thread and play...

2010-10-26 15:20:02.594 App-Final[2345:307] Play

[Switching to thread 14083]

but nothing shows up... Actually, it does go to the 

playMovieAtURL

if I click again I get :

Go STOP received

Actually I do not get where the view showed up ?

any phoneGap developer in the wild ?

Thanks

Hi all !

I hope someone could make a plugin from this. Here is the code that play on iOS 3.2 and more.

I did not test it under iOS 3.2, if any one could it would be NICE !

You have to add the code in your appdelegate*.h

The code is taken from :

http://www.drobnik.com/touch/2010/07/the-3-2-hurdle-of-mpmovieplayercontroller/ and I say a big thanks to him !

Now I need to modify the magic happen code to display the childbrowser view ! and I'll be happy !

[CODE]

@interface PwC_FinalAppDelegate : PhoneGapDelegate {

MPMoviePlayerViewController *mViewPlayer;

MPMoviePlayerController *mMPPlayer;

One more thing for Sencha (and other user)

You should use 

[mViewPlayer.moviePlayer setRepeatMode:MPMovieRepeatModeOne];

for the playback. Sometimes, the view goes back to phoneGap and a GAP appears at the bottom.

It not elegant. Forcing user to touch the DONE button always keep the restored view clean :)

Enjoy !
