Is it possible to play video on an external display via an HDMI connector and Apple TV while having my own app UI on the device?
Yes, it is possible, as the content displayed on the external display can either mirror the current app window, or show different windows.
The Multiple Display Programming Guide from Apple describes the process of implementing this pretty well. You may also want to look into the AirPlay Overview (in the case that the external display is AirPlay-enabled) for displaying video on the Apple TV.

In the new Microsoft Flight Simulator you can pop different cockpit displays out into their own external windows, like this:
However, none of the buttons needed to interact with the displays get "popped out" as well.
I'd like to build a web app that can embed (the continuously updating image of) one of these windows that I can surround with buttons, etc, for interaction to have, say, running on a tablet next to you.
My question is, is it possible with Node to embed the continuously updating image of a native Windows window within a webpage?
Stumbled upon the Screen Capture API. This is what I was looking for.

If you are familiar with scratch, you'll know that Scratch 3 was built to support mobile.
Javascript audio isn't working on mobile devices shows that mobile doesn't support auto playback of audio
Scratch seems to play audio without a problem...
Does anyone know the secret behind Scratch mobile audio playing capabilities? (share pieces of code which scratch uses to play audio on mobile)
(Incase you're wondering why I need to know this, I need to use it on my website)
Read the answer carefully.
Some mobile browsers support automatic playback of audio, but ios, chrome and others require interactive actions to trigger the sound playback.You can try working with the mute attribute..
Scratch can't play sounds automatically. You have to click the Start button on any project. By "interactive actions" they mean clicks, scroll etc,.
I'm developing a Web Application on Tizen. My application was first developed on other platforms like iOS and Android.
Basically it starts on Landscape mode and plays remote content such as image, video or opens a web page. It has a menu inside the app to offer people the ability to change the screen orientation inside the app manually.
This approach is quite easy on iOS and Android but on Tizen seems it doesn't work that easy.
I'm following Tizen's official documentation which send's us to : https://w3c.github.io/screen-orientation/
But, can't make it work even though I followed steps written on the link above.
This is what I got when I try to rotate:
Trying with :
screen.orientation.lock('portrait-primary')
Error :
Promise {}
index.html:1 Uncaught (in promise) DOMException: The page needs to be fullscreen in order to call screen.orientation.lock().
P.S. The app is already in fullscreen. The error is not relevant.
Do you have any ideas ?
Thank you
For all to those who are still trying to achieve this:
After having a long discussion with Samsung, they claimed that supporting the TV orientation via code is not possible right now (Not sure if it's gonna be implemented in the future).
These restrictions come due to different operability of the hardware components on different orientation.
The only way to rotate your screen is to do it via Samsung's TV Settings so that it can prepare its hardware for the chosen orientation.
There are a special Samsung TVs for Advertising market (Digital Signage series) that are ready to set the orientation of the screen.
I comercial Samsung TV sets Tizen is not able to rotate some kind of elements (as far I know the video object are one of the HTML elements that cannot be rotated)
I've developed some apps for Tizen and for one customer I tried to make a video wall but it was impossible due the firmware limitation of Tizen (it's a marketing strategy in order to avoid having hotel and digital signage capabilities in commercial TV sets)
I'm pretty new to IOS4 audio/multitasking and i cant find an answer on this topic:
Got a, pretty easy, two part question:
What framework works in conjunction with the ipod framework? Everyone's seen the pandora app, so the question is:
How do you get the app to notify the user that music is playing (via the purple play icon in the status bar)?
How does this become controllable via the multitasking control bar (ya know, the ones right next to the lock-aspect button)?
It's all the same process.
The play icon is added when you successfully link up your app with the remote play controls (remoteControlReceivedWithEvent). The controls are just events that are channeled to your remote control aware app.
TYPE of audio doesn't matter, as far as i know (MPAudioPlayer doesn't work in the background though).
Hope that helps the newer coders out there :)
I want to develop a j2me application that will play a video file(.mp4) by selecting a particular directory on mobile phone(nokia s40 series).
How do i go about this?can anyone help me to initiate the above said process.
You need to use JSR-135 and JSR-75 to accomplish this.
Check http://www.forum.nokia.com/document/Java_Developers_Library_v2/GUID-96C1B6E4-C266-42A9-9581-A6EEDAC44AC4_GUID-B6B3EB3A-05F6-4CD4-920A-8ED818328681.html for Nokia implementation notes for JSR-75 FileConnection.
Check http://www.forum.nokia.com/document/Java_Developers_Library_v2/GUID-96C1B6E4-C266-42A9-9581-A6EEDAC44AC4_GUID-F227753C-29F7-4056-AB46-1BD80F83E109.html for Nokia implementation notes for JSR-135 Mobile Media.
The Javadocs can be found: http://java.sun.com/javame/reference/apis/jsr135/ and http://www.forum.nokia.com/document/Java_Developers_Library_v2/GUID-D69FC49D-783E-45CE-80D4-7A9F3EE08B2A/overview-summary.html .
Note that only certain directories are exposed via Java ME. You can find information on which folders under the System properties link in the JSR-75 link above.
Basically you want to do this:
Use FileConnection to open a directory and list it contents.
Let the user choose one of the files in the directory.
Create a video player via JSR-135 with the file path as input: Player player = Manager.createPlayer("path_to_the_file");
You also have to attach a VideoControl to the player that associoates a canvas/form to render the video on. (Use VideoControl.initDisplayMode). You also set all the video properties via this control, such as size, location etc.
Then use player.start() to start the playback.
This is a pretty good starting tutorial: http://today.java.net/pub/a/today/2005/09/27/j2me4.html
