jPlayer doesn't play audio file automatically in iPad - iphone

I am trying to play audio file using jPlayer in iPad. It works fine in Safari on my local PC but when I tried to open it in my iPad it doesn't play audio automatically.
Please help me.
Thanks

You may have to initialize jPlayer on user action in Mobile Safari.
The first time a media element is played must be initiated by a user gester. ie., The user must click the play button. This affects the operation of a jPlayer("play") in the ready event handler. The browser will ignore the command. jPlayer will simply wait until the user presses the play button.
Once the first gesture has been received, JavaScript code is then allowed to do whatever you want with the media element. Note that a jPlayer media player instance uses a audio and a video element. Each require their own gesture.
As a hack, you could possibly add a handler for a touch event on an outer container element (or body) and initialize any jPlayer instances that you want.

Do you mean it doesn't play automatically? Because if it does, I don't see what your problem is.

Check if you have entered the correct path for option swfPath.

How do I enable background audio for an iPhone app

Currently I am designing an iOS application that will connect to a music stream through a network and play the audio to the user.
I have a simple setup with a button the enables the stream to start, and a UIwebview that connects to the stream. When I run the app (on an iPhone, NOT a simulator), the button works fine and launches the Quicktime player to begin playback for the audio. Pausing and playing from this screen works like a charm as well.
However I want my user to be able to start up the stream, turn the phone off (sleep the display) and continue to listen to the stream. However sleeping the display will fade out the audio until it stops playback.
I have tried to go into the app's PList file like a few others have told me to do online and added the field "Required background modes" and added App plays audio or streams audio/video using Airplay to the 0 array field and App downloads content from the network to the 1 array field.
("App plays audio" was not offered through auto-complete even though that was the phrase told to make the stream work. Instead I left it as "App plays audio or streams audio/video using Airplay" before trying it the other way to little more luck)
However neither of these are allowing the audio to continue to play when the display has been put to sleep. Can anyone offer up a suggestion as to how to make it work?
In Xcode 5.1, there's another place aside from the Plist that this needs to be set, Target -> Capabilities -> Background Modes... this seems to do more than just affect the plist, though I'm not absolutely sure of this.
Look here an sample code https://github.com/jsagorin/iOSBackgroundAudio
and here .. some explanations (how to Set UIBackgroundModes key in app-info.plist file, Set Audio Session Category , etc) http://www.sagorin.org/ios-playing-audio-in-background-audio/
Just make an entry in plist
Application does not require background mode and set its value to 'NO'
And add background Mode to VOIP

Play a video whose URL is not known in advance - without reload - without extra tab

I have lots of buttons on a web page. Depending on which one is clicked, I want to play a different video.
A large number of <video> elements doesn't seem to work particularly quickly or reliably.
So far, I have tried to:
Create and play() the video element dynamically, after an image is clicked:
var video = document.createElement('video');
video.src = 'video.mp4';
document.body.appendChild(video.play);
video.play();
This works on iOS 4, but not on iOS 3.
Create the video element before, and just change the src.
Doesn't work either.
It seems like the video object must have already done "it's thing", before it can be played.
Use window.open() to open the video URL.
This will cause an annoying new tab to open, which will remain open after playback has completed.
Set window.location
This will cause the current page to be reloaded after playback has completed, which I'm trying to avoid.
Any more ideas?

UIWebView intercept "setting movie path:" from javascript audio player

In iOS 4, I've got a page loaded in a UIWebView with a javascript audio player. I did not create this player, it is owned by a third party, so I can't tinker with it. When I click the play button, I see an NSLog printout like the following:
setting movie path: http://data.myaudio.com/thefile.mp3
My question is, what is getting it's movie path set and how do I intercept it? The audio will continue to play until I create another UIWebView, or use the built in audio controls accessible by an iPhone home button double tap, or close the app. I can't intercept the path with shouldStartLoadWithRequest:, the javascript function audio.play() appears to call some built in player directly. I'd like to control where and how the audio is being played, but short of parsing the HTML for any <audio> tags, I can't figure out how to grab that path and point it somewhere other than the default.
UIWebView is essentially a wrapper for WebKit. Apple does not want you to touch anything more about it than is provided by the existing delegate methods.
That being said, you can modify the DOM of any loaded document by injecting JavaScript. This way you could also modify the audio.play to not do anything and instead get the URL to play with your own player that you can control.

How to record a video automatically in Iphone app without user interaction

I am working an iphone app that needs to record a vedio automatically.
I used mobile coreservices framework and using that. I made it to came into video mode and clicking on record option its start capturing a vedio. But I want it automatically that is.. I should able to record a video without clicking on record option. That is when video mode comes up its automatically start record video.
Could any one help?
You can look at UIImagePickerControllers startVideoCapture method which is used to start taking video from the camera, this is to be used when you arent using the camera standard controlors and you provide and overlay view. Here is a reference UIImagePickerCOntroller ref. If this is not enough for you, you might want to look into AVFoundation framework which gives you a lot more control over video capturing process...hope that helps

UIAccelerometer is Shaking

I want a functionality in which i want to detect if my device is being shaked.The problem is i can detect the shake with didAccelerate method of UIAcceleratorDelegate , but i dont know how to detect if the device is still shaking. I want to play an audio file when the user shakes the device for first time,i have to check if the user is still shaking the device while playing the 1st audio file,if it is still being shaked, then i have to play another file.
See the sample project GLPaint from Apple which was found by visiting http://developer.apple.com/iphone and entering "shake" in the search box. Developer account not required.
You might consider writing a Method that runs in a separate thread that polls wether your device is being shaken every now and then and fire events that you handle somewhere else in your code (or instead of that, handle whatever you want to handle within the threads context itself, even tough i would not recommend doing that).
You just have to make sure, that your "shake-detektor"-thread exits at some point in time, you probably want to do that when the second audio file stopped playing. So your loop could test on that condition.
Hope I could help a bit.
