To do this you would
Become a developer of apps for android and the roku. I'm guessing you were looking for something made today but you didn't find it.
Once in awhile a member will ask why such software wasn't created. Most of the time there is no need since there are existing solutions such as a video cable (I have one for my phone!)
Doesn't address the need
I think the author wanted wireless mirroring, at least that's what it would be using an AppleTV which receives an iPad's screen stream over a WiFi/LAN connection and transforms it for a wired HDMI link to an HDTV or HD projector. In a conference room or classrom setting, for example, that allows the presenter to walk around and present content directly from their iPad. I work with a university central IT service and am quite keen to find an Android technology that functions like AppleTV's wireless mirroring. The only thing I've been able to find to date is work being done by xBounds. Google search them and you'll even turn up a YouTube clip from xBounds demonstrating their prototype device that's clear and illuminating. I think that's the solution we're looking for but to my knowledge there's no known release date. I just noticed a reference to an AllShare Cast dongle and that also seems to be a good solution, including some enterprise/business apps but I could not find a release date for that one either. And the HTC Media Link HD seemed to me to be far too restrictive in several ways. As another possible solution, I think the concept of using a common Roku box is brilliant since the box hardware, software and functionality are mature and stable but the mirroring app aspects would indeed need to be developed. In any case, if anyone finds good solutions that are actually available for purchase, please speak up!
Now that I've seen HOWEVER
The speed of WiFi is not fast enough to move the screen over so it's not something folk would be happy with.
TODAY. NOW!!! We have VNC but only the folks that are simple users would not be able to get it to work. Maybe that's a good thing because the issue of speed could have the folk that don't understand the system (wifi speeds, etc.) would be very upset.
Still unsure you appreciate the application need
While I've never (needed) to assess bandwidth requirements for iPad WiFi based mirroring, it's certainly adequate for HD movies on Amazon and I've never seen any loss artifacts from the (probably expertly and losslessly compressed) iPad mirrored display so I don't have any reason to believe that should be an issue. Indeed, it all works just fine with an iPad 3rd Gen and AppleTV. You might want to check it out some day in an Apple store.
We're just interested in the same functionality for Android devices and your responses haven't seemed to be addressing that at all.
I've been using VNC (TightVNC up to now and RealVNC this year when I needed best of breed for iOS and the desktop OS's) for years and I certainly could be mistaken but I don't know of any way to use it for mirroring the iOS (or presumably Android) device's display to an HDMI (room class) presentation display device. Conceptually it would require VNC *server* functionality in the mobile device and a *client* of some kind built-in to the presentation device adapter -- and I'm not aware of any such implementations or plans. It would also be an odd and grossly overcomplicated way to do something pretty simple -- transporting a compressed full-screen image stream from the mobile device to the display adapter. Do you do any wireless mirroring at all and if so using what technologies? With due respect, your answers thus far suggest not.
In any case, it certainly looks like the xBounds and the AllShare Cast devices may do he trick once they're available. If you have any actual experience or clear knowledge of any other promising approaches, please do let us know.
Why I can't address this for Android.
There's no app for that unless you count VNC.
ACTUAL Experience is VNC for a demo where we needed to show the screen during the demo. But it's far too fiddly and it FAILS for you in a few ways.
As a hardware and software designer and author (I do write stuff!) I know some of the stuff underneath.
So why isn't VNC a fix for now? I'm only guessing you don't want the PC on the other end.
Wifi is more that adequate. Tell the millions of people that use Airplay between mac, ipad and appleTV everyday that Wifi isn't fast enough. I also use plex to stream video from PC to Roku everyday. Of course, the Roku and Apple TV boxs connect to their HD video sources over Wifi anyway.
Of course it can be done over wifi. All the poster wants is the same functionality that the Apple TV box already has!
Then show me the solutions.
Calling me out like this is fine, but did you supply a solution? (No.)
So it seems you didn't and for now I'm correct. There's some reason why this is not out.
I'm sure it will happen soon, but since you didn't supply the app's name and more, it's not out?
Hardly. Your assessment that Wifi is too slow is what I called out because numerous apps on numerous platforms already do what you said wasn't possible. I stream over wifi with PLEX to the Roku everyday. With a little bit of hunting I found "Juice" for Roku that sounds like it will do a great deal of what Airplay does by allowing you mirror many apps on Android to a Roku box.
But again, my comments were not directed specifically at finding a mirroring app for Roku, instead just to make sure that the community knew that you indeed COULD stream over wifi. A streamed screen content would be no different than streaming an HD movie.
So let's see that app.
WiFi is not up to the task of mirroring a display at the rate needed to play a movie.
And it appears you are confusing streaming a movie with mirroring a display. My background includes video work in DVRs, embedded systems and more.
I'd love to see anyone get a mirror app that could do 1080p over wifi to the speed that is needed but the lag time involved means those that wanted such are usually upset. That is, the GAMER is miffed and unhappy. The person that thought they could mirror the display to play a movie is also upset as the frame rates fall among other issues.
To fix this, you see wireless HDMI solutions. And that's not wifi and it's not "streaming."
-> Thanks for the replies but as the man said "Show me the app."
Not at all. But I know DoubleTwist and no screen mirror.
Thanks for the note about DoubleTwist but where is the screen mirror feature KjelstromJason asked for?
Dude your wrong
Rong Proffitt your completely misinformed.
WiFi is currently mirroring displays at rates needed to play a movie, a game, and any multimedia event you can think of.
I have both Android and iPads, iPhones,and a Macbook Air. They mirror over WiFi, show videos, whatever is on your screen is on the TV seamless and fluid with no stuttering, slowdowns, screen refresh issues or nothing. I can see my mouse not he screen, here the sound from my PC. I play Call of Duty over my AirPlay over WiFi all the time. Everything, all via a wireless WiFi connection via Apple TV. Yes it done today and very normal.
Android obviously doesn't have the capability to do this due to its non-centralized framework. It must depend on third-party apps to pull this off, if they ever do this internally. The only thing Android needs is a protocol to communicate over WiFi all the time.
Visit an Apple store near you for a demonstration.
Show me the app.
You told me to go to Apple for a demo which is OK but where is the Android app and demo?
We know this is possible but where is it?
Show me the app.
sorry for the misspellings
sorry for the misspellings I was using this new Nexus 7 and its not the best at voice typing.
R.P. Your point about show me the app is correct. Your point about WiFi is wrong.
Are you waiting for replys on this thread that was fast!! I am impressed. lol
The forum sends me an alert on tracked threads.
I'm hoping that someone will write this app. There's a lot that has to happen for this to work and on the older slower Androids I don't see enough CPU power to crunch the frame sizes down (that's called encoding) to get the HD display over in time.
Latest on Dream Chip xBounds for Android Mirroring to HDMI
Those of you interested in this topic may want to keep an eye on Dream Chip xBounds. Here's the latest YouTube from them:
It looks like they're making good progress but I infer that they may need a purchaser/manufacturer before we'll see the technology in catalogues. They've been working on it for a long time now ... but it does keep getting better and better so there's hope.
For BitsysDad. I never write it was not possible.
Just that it's not out yet. And those that wanted it now may have to dive in and create it.
There's still issues with slower Androids whether they can do the encoding and what else at the same time.
Recently possible, but only for rooted devices with KitKat
Search for Koushik Dutta's "Mirror" or Cyanogenmod CM11's screencast.
Everyone saying that "Wifi is too slow for movies" must be running 802.11b. Modern Wifi is well suited to screencasting. The quality if not as good as native, but acceptable.
Thanks. Closing this old thread.
Let's call it dated information and hope if folk need this they'll ask in a new post. Times change and answers will change and be outdated as Android evolves.
