Can anyone provide insights into how one might feed video into an android tablet / etc?
I'd like to play around with testing the 3D screen with different video feeds, and I'm thinking about using a tablet such as those found over at aliexpress.
I dont care about the 'computer' inside there even, ideally I'd be interfacing as directly to the display as possible. I just can't find much raw data about the hardware itself.

Hi, I think this will be a bit different type question that you guys are use to seeing. I'm hoping some of the guru developers here have a suggestion or two.
Where I work we do video/image processing mainly for Gov, UAV's, stuff like that. I'm a HW engineer. Today a SW engineer came to me asking if there is a way we could tap the HW in an Android phone to be able to get some kind of timing or sync signals that they could use to correlate data from the internal IMU's (accelerometers) to data being recorded by the video camera on the phone. I believe they are looking into using the IMU data to stabilize video captured from the camera (similar to how we do it on other systems).
I'm not at all familiar with the HW in an Android phone but I image a lot of the key signals I'd need are locked up inside the CPU until somewhere.
To me this seemed like something SW could do. We agreed that writing the typical high level Java type app for the phone wouldn't work. Either too much delay, inaccurate timings, or the App would not be able to get direct access to the IMU data and the video stream to record both.
Is this something that can be done hacking the standard video app? Would we need to get down to the kernel level to be able to properly see/control the video camera and the IMU?
We don't work with Android so this would be very new territory to us. Let me know if you have any thoughts.
thanks

I scoured the internet and these forums for an answer to this but found nothing. Does anyone know if this is possible? I know the max res is [email protected] and that is what my tv displays. I would like to set it to [email protected] (best for movies) or possibly even [email protected] (for gaming).
All I can think of is getting an adapter that tricks HDMI into thinking your TV isnt capable of doing certain resolutions, but I would rather not have to go that route.
Thanks.
if your tv supports it, force it into another resolution and see what the phone does with it. on my tv i can set the resolutions and refresh rates on the different inputs.
unfortunately my tv does not support that, who makes your tv? i have a 2009ish samsung lcd, i am pretty sure i know that tv inside and out but its possible the functionality is hidden away somewhere.
I am currently thinking about building a small streaming device for my home theater.
One idea I am having is to build a lightweight NAS out of a raspberry pi b board and add a second device running xbmc or plex for streaming from the nas.
As there are currently hundreds of android sticks (and no one really seems to know which one is best) it got me wondering if I could not just use my old Galaxy S?
Is there a way to stripe all phone related stuff from it and just have some kind of custom rom that uses the hardware like a regular android tv stick?
It really only needs wifi, hdmi out and enough power to run xbmc + stream in 1080p.
Does anyone know if this is possible at all?
AFAIK the HDMI out of the Galaxy S does not work in custom roms because it uses proprietary Samsung code. So it is probably impossible. I also seriously doubt that the hardware of the Galaxy S is capable of displaying HD media in full resolution.
I am hoping that as a newbie, someone might give some advice into a Wall Mounted Photo Frame that I have been thinking about.
My purpose is to display mostly High Resolution Animated Gif Art and Cinemagraphs. No Photo Frames can do this.
My idea is to place a 23” or 24” ultra thin monitor into a picture frame and mount it on a wall. The monitor will be powered by an Android Mini PC such as the Android mini PC RK3066 or something similar.
I was going to plug the unit into the HDMI port on the monitor.
I currently use the Quick Pic App on my Asus Tablet to view animate Gifs as a slide show. If someone knows another app please let me know.
In order to make the frame on the wall more esthetic looking, I was going to use a monitor with an external power supply so only one small wire comes down the wall. The power supply will be a brick on the floor. To power the Android Mini PC, I was going to use a power splitter and a stepdown 12v – 5v 3a converter.
To store my images on the unit, I want to use a 32 gig SD card and move them in via wifi. I also want to utilize a Bluetooth key board or wifi in case I want to bring image in from the net.
Does anyone have any experience in this area? Also is it possible to boot right into the app so when I turn it on it will begin to display right away without a pointing device to get it going?
Or even better is there another way to approach this project?
Looking forward to hearing from all.

The is a free Android app called "Startup Manager" which i use to block certain apps starting up on boot but am sure it has options to force start apps on boot.
ive read the people use it to boot straight into XBMC so might work for your Asus app

Hi,
In my opinion and from a longer term prespective, the features you are looking for can be achieved much better with an open source digital signage such as xibo.org.uk. In addition to playing animated gif's and images you can play videos, webpages, scrolling text, RSS and scheduling content and much more compared to a simple slideshow app.
Xibo is a client server app so technically, you will need to have two separate machines, one for XIBO CMS (server) and XIBO Android player app each. Xibo for Android app from springsignage.com is only $15.
However, I (and not many have done so) being an experienced xibo user was able to successfully install and test both xibo CMS (server) and XIBO android app on same TV stick/box and then control the CMS over network (wi-fi/internet/LAN) etc to manage and schedule content for the player app.
You can get started really quickly with free and fast help from xibo community forum members.
However,If you want a set up like the one I did with xibo CMS and player app on same tv stick with auto launch of server (CMS) and app on device startup and many other technical hurdles/setup details then we can discuss this further for a bounty.
Pls send me a private message (PM) if you want my paid service so that we can discuss this further and I am confident, I can setup you up for a long term solution.
Thanks and best of luck with xibo.

I have what's been labeled as a 'Smart TV box'. Its android and runs some software that allows me to watch certain channels and movies which I have to subscribe to.
My subscription has ended and I have a '''useless atm''' (--> potentially useful ) android device. It has some software on it that still works, but I want to mod it, if I can and also root. How do I go about doing this?
Can any of you android people out there help me?
Ask me if you need pictures or something?
If you have a Android TV box you may look into using the Kodi system you will be able to keep watching free TV on it look into it search it. You may look on YouTube

Details Needed...
It would seem to me more details will be required. Rooting methods vary by SoC maker(AmLogic, Rockchip,Etc.) and box model. There is info on the unit's PCB that will be useful to those trying to help.
SoC maker:
PCB maker, info on PCB - model#, revision and date:
Software version: Android 4.2, 5.1,etc:
Specifications - CPU type, amount of RAM, Storage, WiFi module, etc.
Decent quality photos of your device may also be helpful.
Good luck.
