Which Device shall i buy to have fluid HTML5 chrome based animations and youtube 1080p support?

Hi everyone,

i've developed an android app which mostly (ab)uses androids browser to view some html5 content including animations like css based, video-tag mp4 videos or youtube embedded videos.

So the main question is which devices could you recommend which has good hardware, is small like a tv box or such and has good support for custom roms?

Currently i have a bunch of (alibaba bought) devices here which i tried to customize so my app runs as android starts to get better customer expirience. So the purpose is to kind of resell the device.

My problem is that those tv box devices like (Q8 quad core - rk3288, or a second one which could be a amlogic 8726 M3) dont seem to be stable.
I get sudden reboots, sometimes chinese advertises, suddenly the device is non-rooted anymore and i need to rerun some chinese app to root it again and there are apps installed which i cant even read cause of chinese characters.
Also the animations aren't that much fluid.

So i tought about searching for a custom rom which may fix above problems and i must say i can't see the wood for the trees anymore.
I started with the question on how to flash a rom which led me to twrp, cwm, fastboot, flash_image and androidtool or such?
Then i tried to find a recovery image which fits my device i hope i get update instructions. Not finding anything i could fully understand i headed forward to finding a custom rom so i maybe could just wipe the current image with onboard recovery but i only found openelec,xmbc images which are too customized or stock images linked to some china sites where i'm not sure it would make any difference.

So, just out of curiosity:
1) A recovery image like twrp or such is tightly coupled to the hardware it shall run on, right? That's why there are threads like "twrp for amlogic devices, rk3288, .....". So if i make a wrong decision he device becomes unusable?
2) How is a custom rom created/compiled? It seems that, for the devices i was looking for, only the (chinese) manufacturer provides rom's and it seems that everyone bakes its own solution like because some other video decoding chip is on board or such. Why is it like that, that one can't just download the rom source the manufacturer used an modify it or add my own replaced graphics driver to get more fluid animations or such?

thanks for any answer/help on this

Could you post a 'website' or benchmark.. we can try.. for you
Or perhaps you can post your made app..


Html5 depens alot on Cpu/browser used.. (even what firmware you are running.. hw acc)
-i use firefox /aura nightly.. if you look under the hood.. alot of functions are disabled (aka tweaks can make alot difference)

Just a thought

thanks for your comment, mitchell

unfortunately i can't provide you source since everything is developed as closed source
and everything is an early stage yet
but as an example, a website like this

http://demosthenes.info/samples/polina.html

http://greensock.com/gsap

should work smooth in 1080p

but to give you an idea, the app will use a GUI which is mostly driven by androids webview class.
So everything performance/video/html5 related depends on android's chrome (which is used by webview).
Something else is not an option because our customers need to modify the GUI and include html5 animations which must be embedded by the app and thus webview.

That's why my question is some kind of general. It should work out of the box with good hw acc.
So i need the right combination of hardware and (maybe customized, like finless or such) android
to get fluid chrome browser video support.

thanks for your time and help

I am a mobile app dev and use phonegap as a framework. I believe html5 apps are better rendered on webkit based webviews and using latest V8 js interpreter engine.
That means you have to embed your app on a device using the latest webkit and V8;
logical choice is then lollipop 5.1;
but no chinese device will offer that for now.
