AppleTV Screen Mirroring API

Hi,
Is there any documenation of how AppleTV Screen Mirroring can be used from custom application and other platforms.
It can be a great thing to make other products work with AppleTV device.
Thank you,
Dmitry.

If there is then there is a 90% chance of you ger Info about it if you ask here

Apple TV Screen Mirroring API

Hi,
Is there any way to get Apple TV Screen Mirroring API, so it can be used from application?
I search over apple forums and haven't found any documentations.
Thank you in advance,
Dmitry

Is your application on OS X or iOS? You can find good information in the AirPlay documentation. Sample iOS Links:

AirPlay Screen Mirroring (Mavericks) disconnects frequently with "Feedback taking too long to send" message

My company has several TVs with AppleTVs (3rd generation units) connected in our conference rooms so we can "Screen Mirror" our Mac laptops via AirPlay during meetings. Many employees have complained that AirPlay Screen Mirroring drops frequently during meetings for no apparent reason.
In attempts to determine the cause of the issue, I removed the AppleTV units from Wi-Fi and hard-wired them all to the LAN (100Mbps/Full duplex, no switchport errors seen on the Cisco switch). I upgraded the AppleTVs to the latest firmware. I had our AppleTV users ensure they were running MacOS Mavericks with the latest software updates installed. I had the Mac laptops hard-wired into the LAN during meetings in the conference rooms. None of these changes resolved the AirPlay issue.
I reviewed the MacOS "/var/log/system.log" file from the laptops of several users that reported issues. I found a pattern that seemed to indicate that the "coreaudiod" process reported "Feedback taking too long to send" several times before the AppleTV connection was terminated. Also, from a network trace (using "tcpdump") taken during an unexpected AirPlay Screen Mirroring disconnection, I could see that the Mac laptop sent a TCP FIN packet to the AppleTV unit (this would indicate that the MacOS laptop initiated the closing of the AirPlay connection).
I have included the relevant log file entries below. Please note that the LAN internal to our company is "solid" and there have been no connectivity issues detected or reported during the times the AirPlay sessions were disconnected.
I believe I have found a workaround to this issue. By going into "System Preferences", "Sound" and then changing the "Output" device BACK to the "Internal Speakers" (rather than the AirPlay destination), the AirPlay Screen Monitoring connection seems to remain stable.
My questions are:
- is anyone else experiencing this type of problem? any other solutions recommended?
- is there a way to change the AirPlay defaults so that Screen Mirroring only sends the video (not audio)?
- does anyone know what the log file entries indicate (like, what does "Feedback taking too long to send...." mean)?
- any fix planned for this issue?

I'm currently still experiencing this as well. I've confirmed it occurs on 10.9.1, 10.9.2, and 10.9.3 on MacBook Pro Retina's, Mid-2012 and 2013 MacBooks. It happens on multiple ATV's not just one, all are updated to 6.1.1 and a simple reboot seems to fix it temporarily but it does come back. All the ATV's are connecting to the network via Wireless not Ethernet. These are 3rd Gen ATV's but I checked the serial number and these do not match the bad batch of Apple TV's from 2013 that were offered up for Replacement for Apple due to the bad firmware update. None of the computers have the Firewall turned on. Here's the two logs that we always find after the issue occurs (logs are recent, happened this morning):
5/30/14 8:57:36.017 AM coreaudiod[183]: 2014-05-30 08:57:36.016946 AM [AirPlay] ### Feedback taking too long to send (30 seconds, 17 total)
5/30/14 8:57:36.332 AM coreaudiod[183]: 2014-05-30 08:57:36.331492 AM [AirPlay] ### Feedback failed: -6723/0xFFFFE5BD kCanceledErr
The user will get disconnected from Airplay anywhere between 30 seconds to 3 minutes after logging on and can reconnect but then once again get disconnected after the same time period. One interesting thing to note is that when the Feedback Taking Too Long to send error starts occuring and the countdown to disconnect start ticking down to 30, its solely referring to Audio not being sent over the network and Video is working just fine. If I try to play sound I get another log and the sound doesn't play through the speakers. After a reboot, sound works fine and the Feedback Error's do not show up. I've also tried switching to Internal Speakers (since it defaultly switches to Airplay Speakers) after connecting to Airplay and seeing the Feedback timer start in the Console Logs but even after that the log continues to saw its taking too long to send and disconnects in 30 seconds.
This issue has been ongoing for months, I've got a ticket logged as far back as January with this occuring but its infrequent enough that we've just restarted and moved on. I'd say its an issue that occurs to about 5%-10% of meetings but that's an entire meeting that doesn't have the ability to Airplay until someone comes down and reboots it.
I don't often post in this forum but its still an active issue with no resolution, proof that its occuring on other people's systems, and no firmware updates having been released to correct it. It'd be nice to know of any workarounds other than having to buy some lamp timers for each conference room just to get a functional ATV or putting up a sign that says hey if you get disconnected every 3 minutes, reboot the ATV. The whole reason we're using Apple products is for ease of use otherwise I'd put together a much cheaper solution myself. Any help or recommended troubleshooting steps would be fantastic at this point.

Video and sound slightly out of sync when screen mirroring

When I start screen mirroring and play a video, then my macbook screen matches perfectly with the sound output from my stereo, but my tv is slightly delayed compared to my macbook which makes the sound and video out of sync. it is something like 1/10th or 1/20th a second, but it is extremely annoying.
Anyone has the same problem or knows how to solve this?

What format were the original items ?
What frame rate are they in the original ?
What format are they on the AppleTV (H264 video AAC audio is the most common, but there are others) ?
What is the video frame rate now ?
Most out of syncs come from an imperfect attempt to encode for AppleTV. ie. DVD frame rate is 29.97fps. Many encode this to 30fps. So the movie plays 0.1% too fast, too little for you to notice, but at the end of a 100 minute film, the audio is 6 seconds out of sync with the video. Or 3 seconds on a 45 minute TV show.
Also check the source. I'd had DVDs (Alien Resurrection) jump 10 seconds out of sync in the middle of the movie. Back to the shop for that one.

Encore WT8 - screen Mirroring on TV does not work

Hello,
I have a KDL42-W653A television which supports screen mirroring over WiFi.
However, I cannot get it to work with the Toshiba Encore W8 tablet.
The tablet detects the television, I enter the number, but the television never shows the tablet's screen.
Both the television and the tablet are on the latest firmware.
Another thread indicates there is an update for HDMI in January. I hope that covers this too.
Anwar

Hi
> I have a KDL42-W653A television which supports screen mirroring over WiFi.
By mirroring over WiFi what technology you mean exactly?
Miracast, Intel WiDi, DisplayLink?
Toshiba Encore supports *Miracast*
To use Miracase both devices needs to support this technology.
Then you can connect to external display very easy:
Tab Settings -> Change PC settings -> PC and devices -> Devices
Here you have to Add a device and you tablet will start searching for a Miracast devices
After the connection has been established, the name of the Miracast device will appear under Projectors
Did you test the video output connecting the table to the TV with an micro-HDMI cable?
Does it work?
Here is also an nice youtube video about the Toshiba Encore WT8 screen output options

Screen Mirroring does not work, full of bugs.

Hi,
I've had a Sony Z1 for well over six months now and have got a Sony Bravia TV that supports mircast screen mirroring. When I purchased the Z1 it was on android 4.2 and the screen mirroring worked a treat, it was lag free, always responsive etc.
But when I upgraded to 4.3, the mirroring was buggy as **bleep**, the device always disconnected, when it did connect after several attempts it would lag, black out, then disconnect again. I've tried fiddling with wifi settings as well as wifi direct etc. but no joy and I left it as that.
When I knew 4.4 kitkat was coming to the z1 I waited as I would assume the issue would be fixed, but I upgraded to 4.4 (build: 14.3.A.0.757) today and is still full of these disconnecting and unresponsive bugs. I'm not sure what the problem is, I mirrored a samsung s4 mini and works absolutely fine (4.2) and I can mirror my sony xperia tablet z (4.3) with no issues either. I know a relative who also owns the z1 and has exactly the same issue, what also seems to happen now and then, is that half way through a mirrored session, the wifi would disable and will switch to the mobile network, then after some time, back to wifi again; yet this never happened on 4.2?
Is there a fix or a way to solve these issues? It's rather annoying having such a great feature that doesn't want to work on a flagship.
Thanks.

I had some issues with Miracast on my Z1 but with 4.2 and 4.3 firmware. It was loosing connection or kept saying that I don't have HDCP. I was connecting using Netgear Push2TV.
On 4.4 (.757) it works quite stable. On Z1C with 4.3 I wasn't able to miracast at all.
The same goes with screen mirroring to Z2 tablet. Works fine from Z1 to Z2 (both KitKat, altough one touch pairing is a disaster and not working at all), but you can forget about it using Z1C and Android 4.3.
Best regards,
Sergio PL
Xperia Z1 / Nexus 7 (2012)

Could not turn on Screen mirroring. The output device is not ready or does not support HDCP

i tried it on my tv sony bravia w700b with my new xperia z1
i didnt unlocked my bootloder or i didnt rooted my phone
dont know whats the problem is
'Could not turn on Screen mirroring. The output device is not ready or does not support HDCP'. can anybody able to tell how can I resolve this please?

Have you checked if your device does support HDCP? I looked at https://www.iezvu.com/ezcast.php?l=en but i'm afraid i can't find any detailed specification for it.
If you have unlocked your bootloader this may also be the cause for this issue.

Airplay icon doesnt show/screen mirroring option absent in display pref

Hello all,
I have searched every where I can and cannot seem to resolve my issue.
I have an Early -2011 17" MBP and a new Apple TV.
Everything on Apple website/support page tells me that my MBP SHOULD be able to use Airplay but I cannot get the Airplay icopn to show up on the top bar.
The Apple TV is working fine with my IPAD 2 and 2 Iphone 5s.
I have also checked the "display" properties under "system pref" and the option to check/uncheck "screen mirroring" isn't there.
Apple store person confirmed via Apple website/support communities that my Early 2011 17" MBP running 10.7.5 does/can use Airplay.
Can someone help me?
What am I missing here?
Thank you all in advance for your help

It is your OS, you need OSX 10.8 Mountain Lion or newer to mirror.

Airplay screen mirroring on 4:3 projector, resolution problems.

Hi!
I have an iPad 3, an ATV3 and a NEC NP400 projector which I'm trying to get to work together. I'm not sure about the projectors resolution, but i know it has a 4:3 aspect ratio.
I've tried to use screen mirroring with both the ATV 3 and a VGA adapter, and the problem is that I get black bars on each side no matter which method I use. I understand that the iPad 3 has a 4:3 aspect ratio and that black bars would appear with a 16:9 screen, but not on a 4:3 screen which is the ipads native aspect ratio.
It feels as if the iPad by defalut assumes that I'm having a 16:9 projector and adjust the aspect ratio to that fact. Is there anyway to tell the iPad that i'm having a 4:3 projector? Or should it detect that automatically?
The ATV fills the whole screen without black bars on each side, but as soon as I'm turning screen mirroring on via airplay the aspect ratio changes. There is no difference if I'm using the ATV or the VGA adapter.
How does these things work, and is there a solution?`
Thanks!

Welcome to the Apple Support Communities
See > http://support.apple.com/kb/HT5404 AirPlay Mirroring is compatible with Mid 2011 and newer MacBooks Air, and OS X Mountain Lion.
As you have Mac OS X Snow Leopard, you haven't got a compatible MacBook Air, so you can't use AirPlay Mirroring. However, you can use a third-party app as AirParrot to mirror the MacBook onto your Apple TV > http://www.airparrot.com

Can I screen mirror on a Macbook Air version 10.10.3?

I've just bought a Macbook air running OS X Yosemite and i have been told that they can screen mirror without any wires or apple tv, but I don't have a clue how to get it going.
please help

Sure, here's the solution:
The "Share" button was introduced with Mountain Lion! You should buy the Mountain Lion upgrade if your MacBook Air can handle it.
Here are the requirements:

Chromecast Screen Mirroring

Hi,
Google released and unlocked the native screen mirroring via Chromecast. Why is SONY the only BRAND that is not listed in supported devices ? Can't be that hard to do...I buy a Flagship Device and get a knock into my face for it...Please get in contact with google to add the Z2 to the list of the supported devices ASAP!
greetings.

Download an app called Allcast. Works great but you have to pay about £3? after the initial trial.
Great for watching movies from Showbox

Screen Mirroring

Can somebody explain tom e what this exactly is? I am using my galaxy note 4 and when I try to scan with it I can't recognize any of my sharp smart televisions both the tv and the phone are connected via wifi on the same ghz/network
I assume screen mirroring is bluetooth devices though?

My apologies, I actually made a mistake when I wrote my original reply. Your TV should support DLNA protocol, which based on the specs of the comparable model you sent me, it should be able to work.
I did some further research though and found that Samsung phones sometimes don't wirelessly mirror the screens to non-Samsung smart TVs without an additional accessory. It's called the AllShare Cast Wireless Hub (click here for item info) and plugs into an HDMI input on your TV.
If you are able to provide me with the model number for your current TV I can do some additional digging to see if this device would be required for your specific TV or if you can just mirror your screen without it.
-- Alex
Bought the TV more than 18 months ago so I am not 100% sure as to what the model number is to be honest. I was just able to go and compare similar specs.
I know for a fact I have seen something about DLNA protocol under settings I will have to look at that.
Will also do more research on that accessory thanks.
If I can get the model number I will post again. Thanks
