Have little experience with mobile web apps, but want to create an almost stereoscopic image(identical side by side images) of a site (192.168.2.87:8080/jsfs.html). Does anyone know if this is possible with a mobile web app?
In context, it's a video feed using javascript from IP Webcam for Android, and the video is actually rendered in the browser itself by putting together still shots.

We are developing a video streaming website and have a business requirement to stop playback, if any external display (e.g. TV) is connected to the PC through HDMI.
Is it possible to check this in javascript?
I tried using Presentation API and Remote Playback API supported on browsers, but they seem to work only for "casting" and not for simple media "mirroring" through HDMI.
The w3c spec however specifies that the Presentation API is meant for 1-UA (User Agent) mode as well (simple mirroring through HDMI).
Somehow I am not able to use Presentation API to check if any display device is connected through HDMI or not.
Can anyone help me out with my query?
Basically, I have an idea for my App, I would like the iPhone camera to keep recording a video even when the user is doing something else (like checking twitter, for example) like a spy cam. I have many coding solutions available
Is there a way I can code this with either HTML5 ,CSS, javascript or xcode?
iOS will not allow you to run the camera constantly in the background. This is because once each app enters the background state, it only has a very short time to wrap-up it's processes and prepare to be suspended (iOS does this to conserve memory).
From the apple developer docs
In iOS, only specific app types are allowed to run in the background:
Apps that play audible content to the user while in the background, such as a music player app
Apps that record audio content while in the background
Apps that keep users informed of their location at all times, such as a navigation app
Apps that support Voice over Internet Protocol (VoIP)
Apps that need to download and process new content regularly
Apps that receive regular updates from external accessories
The only other way to achieve what you want is to jailbreak your device and distribute your app on Cydia (the jailbroken App Store). Jailbreaking will free your device from the restrictions of IOS but will also make your phone a lot more vulnerable to being hacked...

I want to be able to periodically send gps coordinates back to the server? Can this be done if the screen is off?
If not can some alternate approaches be suggested..
If you are good in javascript and html you can go for phonegap. this framework will work like a native application and running from webview like browser. Since phonegap is a cross platform framework you can make your app compatible to many devices like windows phone, Apple, Android. To know more about phonegap or cordova click here
And yes phonegap does many function or features that can customize your application in many way. for example "WAKE LOCK" which keeps your application awake till you force close it.
or if you are using browser you can not run your code for long since browser is a big application android or your mobile system will close it.
I'd like to create a web page which can access a body sensor on an Android tablet (to detect if someone is standing in front of the tablet).
I'd love to do this with a web page (an actual web page, not a PhoneGap/Cordova app). I've seen demos of accessing the webcam from a web page via HTML5/JS in Opera. I'd love to do the same with a body sensor.
Is there ANY way to achieve this? I'm okay with using a browser plugin if necessary or even a customed Android browser (that supports HTML5/CSS3).
Alternatively, is this even possible with PhoneGap/Cordova?
I am experimenting with Sammsung Smart TV Javascript SDK and wonder that I cannot open Links in System browser.
I have found this Samsung Smart-TV SDK Internet Browser not available which is not what I want because it is not possible to navigate in this window via TV remote control.
Samsung doesn't give web browser in their SDK because the actual application also cannot open the web browser, so there is no point to bring web browser to SDK.
Developing the TV Apps is little different with mobile apps, in the mobile we can bring our ordinary website and put them on webview or html viewer because the navigation for click and else is same with desktop browser. but in TV apps you should utilize the remote control as the main input.
