Miracast on the Nexus 7?

In articles released today, Nvidia said the Tegra 3 chipset will support miracast (an open streaming tech similar to DLNA) for mirroing/streaming to other devices/ monitors. Will the Nexus support this and would this be their workaround for forgoing the MHL/HDMI? Or would it only be on future models? -Ara

I'm very curious about this too.

I've looked into this briefly and from what I gather, any device that supports WIFI direct should be able to do this. I think I read somewhere that the N7 has wifi direct. Miracast is only a standard. There are other non-standard devices out there that can also do the same thing, but requires changes to the core android files.
Search for xbounds on youtube and the internet. You will see some demos of it. it requires an hdmi dongle that has wifi on it that communicates with your device.
In any event, if the N7 doesn't support miracast, it will support xbounds via a custom ROM (if and when somebody decides to build a custom ROM with xbounds integrated). Then all that is required is the xbounds dongle. Unfortunately, there is not much information on xbounds and when it will be released.

What would I need to purchase to get this working?

Hopefully, we don't need to buy stuff, we just need to update our devices when miracast comes down. There's a list of compatible devices on the Wi-Fi Alliance website. -Ara
EDIT: here's a link to the tegra explanation of miracast, taken from an article on the issue. Yeah, a dangle may be involved depending on the setup. http://www.nvidia.com/content/PDF/tegra_white_papers/tegra-miracast-whitepaper-final.pdf

I've not found any hardware that you could plug into say an HTML Monitor that will work with this yet. I do think it will be coming available soon though.

hope so
I reckon it will work with a Nexus 7. Hopefully the dongle isn't too expensive and my Nexus 7 will be my new PSone.

Shouldn't need a dongle. Maybe a Raspberry Pi but everyone should have one of those anyway Search "Android Transporter" for more info.

Nexus Q might get Miracast support
Nexus 7 and most Tegra 3 (also Galaxy S3) phones/tablets can get a fw upgrade to enable miracast (most that support WIFI Direct probably can have Miracast enabled).
Now that google is having another round of tinkering on the Nexus Q before release we might end up with Miracast support in it as well.
Personaly I think Miracast will be added out of the box and maybee even Google TV.
I only hope that it won't be possible to disable mirroring from inside an app using the API, if so I'm sure some streaming services will disable mirroring of the screen while using there apps lika HBO Go have done to Airplay

Using a Raspberry Pi would be like a dongle... I'd like to get my hands on one to play, currently, there is a 12 week delivery time on those as well and you most likely would want it in some sort of case for it as well.
While most likely a solution, not a real clean one for mass marketing. That will come though.

Hopefully it does include support, but that is still a bit pricey and also not very portable.
Think of something you put in your briefcase, take out for a meeting, plug into the HDMI port of whatever display is in the room and play. So it needs to be portable, reasonably priced and easy to use out of the box without a lot of fiddling with it.

widi and Miracast adapters
I am thinking that these will do what we need on the display side. Now to enable it on the Nexus 7.

Has anyone heard any updated news on miracast? I tried Google but all I found was old news. I'm really tired of waiting.

Nexus 7 android 4.2 questions

Does the device with android 4.2 need to have a special chip set to do the new wireless HDMI out? Also what is this adapter that I need? I can't find very much information on this, seems like I'm the only one excited about this...

I would hold off on buying an adapter.It seems only the nexus 4 gets miracast from the 4.2 update.Maybe one day we will see it on the N7 but for now nobody has shown it working on anything.

[Q] How do I share my screen on to my HDTV?

Well I read so many threads about it but it got complicated after the 4th sentence and I don't understand a thing.
I have 1080p LG HDTV 37LD420-ZA bought in 2010. I have no idea about Miracast, what it is or do I have it. Can I even set up this stream or?
Thanks

Holy crap I swear the lack of information on miracast will be its demise. Its seriously pathetic that one can't even simply search for 'how to use miracast' and find simple answers. Miracast is seriously the equivalent to a unicorn at this point.
Somebody PLEASE prove me wrong. Its my most anticipated feature of 4.2.

What you just said is completely right. I tried many sources but nothing :/

Bubble up player is great to stream from the tablet..
I use it because you can pick the device where the files are at. Say on a network computer share folder. Stream them thru the tablet to a Tv on the same network..
You can also select where the video is rendered .. Local ON THE SHARE Device or on the ..
MY Samsung shows up as a DLNA /Media device on all my networked devices . Its great feature..
YOU just have to play with the settings to find what works best with your tv and network shares.. There is also a SAMSUNG ALL SHARE App and program for windows pcs. that does NOT Require a samsung device..
As far as miracast who knows if or when....

The thing is, I don't want just DLNA playing to another device/computer/television. I want mirroring. I want exactly what Miracast is supposed to give me. And even now if you Google how to use Miracast you will find *nothing* about actually *how* to use it. You see a whole bunch of hype about people saying how it's going to beat AirPlay and how it's the best thing since sliced bread -- yet nobody has actually used it.
It's appalling how biased people can be without any evidence of the feature working (short of a video given to us by the friggin manufacturer). I feel like I purchased an iDevice. This feature is a ghost.

Exactly, feels like there are more Andro Sheep than iSheep. For now, 4.2 only brought amazing Bluetooth-NFC connectivity. As well as some UI stuff which there are plenty of custom on Android.

What good is it without dongles easily Googlingable? I G+'d a collection of certified devices a while before 4.2. Ain't been able to find a one. And Samsung's AllShare Hub thing wasn't one of them.

Well I, for one, wouldn't even be connecting it to a TV. My home theater PC, however, should easily be able to have some sort of software running on it that would be able to receive the signal. The problem is that the functionality is only half-baked at this time no matter where you look.
And without any device currently on the market, how can people swear by it?

Before we all start a witch hunt, remember miracast is still in development. You can't have something that hasn't had an official release yet.
Android Central has had a few articles on it, so far there are no official streaming devices for it (although some companies have claimed their upcoming streaming devices will support it).

Our best hope is that Google enables Miracast in a future update, and that compliant Miracast devices are released. I'm not holding my breath, since I would have thought that they would have included it with the 4.2 update if they planned on including it at all. I could be wrong of course. It's still early days with Miracast. Maybe it can be enabled via custom ROMs.
It would have been awesome to be able to stream games to my TV. Along with a bluetooth connected PS3 controller it really could have been an awesome experience.

Lazy, bad reporting.

They don't mention the 7 in the article, just the 10 and 4. I don't mind living without mirroring (my phone has MHL, if I ever bother to buy the adapter), but the wireless mirroring was a selling point on this tablet for me, even if I have to go custom to enable it.
As a filmmaking student, the capability to control and mirror screens on, say, a movie set, or a classroom, without plugging everything up just so, sounds pretty sweet. And I'm personally just tired of collecting single-use cables and adapters.
Patience, however, is a virtue, and I am willing to wait for Google to get off their asses once the mob realizes the shortchanges they're giving us. -Ara

What I don't understand is why did they hype it so much? From what I understood, no ones TV even supports this yet. Am I supposed to buy a new TV for this feature?
And I also don't understand, how is N7 not mentioned in those articles? Official Miracast video says that this is going to be enabled for NVIDIA Tegra 3 devices. Only N7 has Tegra 3, N4 and N10 both have different stuff inside.
This thing lacks so much information.

Yeah, prob a mistake to hype it so much. I mean, wait until the ecosystem is ready. Airplay has been out for so long it seems. Get off your asses, Google!

any devolopment?
Any devolopment on this? I just searched for an hour and only came up with articles on it, no downloads or hardware..

Media link HD = Miracast?

I know, I know, there's little hope for mirroring our nexus 7's but the mirroring technology is available via Medialink HD. As far as i know, the HTC One series are the only brand of phones able to mirror without using miracast. Can anybody clarify as to if it is a software enabled thing or hardware? Because if it is software, maybe we can somehow frankenstein it into our nexus 7 to mirror it that way?
It may just be hopeful thinking, but thought I'd just throw it up there.
Sorry if there is already a thread on this.

[Q] Did Nexus 7 get Miracast Support with 4.3?

Hi everyone, I have a quick question and haven't been able to find the answer anywhere.
I just got the update to 4.3 last night on my Nexus 7. I forgot to check about Miracast support. I usually leave it at home for my wife and daughter and take my Nexus 10 to work.
I know the Nexus 10 got Miracast support with 4.3, but I need to know about the Nexus 7 and don't have it here to check. Can someone let me know?
Trying to swing by Best Buy on the way home and pick up the Netgear PTV3000

That's some BS. Do you know of any mods or ROMs that have added the support yet?

There is already a working Miracast rom, but people/dev don't seem to be interested, so I don't think this rom will be include it to the other popular rom out there for the Nexus 7 (2012).

This I never understood, why is that? I would have thought developers would have been right on to this. But kensuke has shown it is possible.
And watching the videos I think it's fantastic. Yes the gaming one had a bit of latency, but it looked minimal. Afaik, other devices (n4, n10) that officially support miracast have similar latency so I don't see why the n7 wasn't officially supported. I'm way more excited about this than chromecast which everyone seems to be freaking over.
I had a look at kensuke's page hoping for news on this being in 4.3 and saw this:
""Remove all traces of wifi display sink implementation and supporting code." "
Sink implementation means that a miracast device can act as a host. So you could miracast from one nexus 7 device to another.
But google has removed sink implementation in 4.3 source! Why would they do that?
Not that I would use the sink feature al the time, but it could be cool where you are trying to demo something to someone, they could just connect to your device and show them. I could think of lots of cool features with that, but for whatever reason, google has removed that code.
Yes the code is there in 4.2.2 but I imagine trying to put old code back can be difficult.
I read that from here:
https://github.com/kensuke/How-to-Miracast-on-AOSP/wiki/Android-4.3
I hope he's successful in getting miracast to work in 4.3 and I also hope he can reimplement the sink feature but again, I understand that may be difficult because of google removing it.
When I saw the gaming video here:
http://www.youtube.com/watch?v=20s567tzTdM&feature=player_detailpage&t=316
I noticed how good the picture was. It made me wonder if there was anything in the miracast spec on performance/quality settings. When miracasting a movie I'd want the highest quality and wouldn't mind latency, but with a game or any realtime app, the less latency the better. I wonder if encoding at a lower bit rate would help tackle the latency? Maybe not as it's hardware encoding the steam and it's the onboard encoder chip and not the settings that would influence latency.
Thanks to kensuke for his efforts. I'm still somewhat surprised that it's taken this long for a developer to attempt to tackle this.
And I really hope other devs would show interest and incorporate this into their roms.

Im really surprised to see that no developer other than kensuke is interested about miracast support in nexus 7. This would be the best Customization ever done for nexus 7. A lot of people would be loving to have this feature yet there is only one rom which kensuke made for only miracast test purposes. It can not be ported to 4.3? - dont mind using 4.2.2 until i upgrade to 2013 nexus 7.
Devs hear us out!

Hi guys. Yesterday i bougth SONY TV with miracast feature. Can i use mentioned ROM to mirror screen of my N7 to SONY TV. I am still using Parandroid ROM(v.3.60) based on JB 4.2.2. Do i need to flash whole new ROM or there is any script or application that i can use?
