AirParrot AirPlay Screen Mirrioring

And i'm unsure if you understood what airplay mirroring is. If i got you right it won't help you to achieve what you want.

all I want to do is get my mac or win computer's screen to show up on XBMC.

Did some more tests yesterday and was able to accomplish that. With advanced launcher and VNC, it is full screen and not too bad. HOwever, how I cannot exit VNC and go back to XBMC .

I am driven to find a solution to this!

then airplay mirroring wouldn't solve it

yes, AFAIK airplay mirroring works the other way around. You're not connecting from your device to a remote client to see it's desktop, but just send your desktop to a client. So you don't ask to see a remote desktop but simply push yours somewhere. In order to make this work the way you want it to be, you would have to start XBMC (once mirroring would be in), then go to your other computer and start mirroring from there.

Don't think mirroring is possible from othere devices beside iphone4s and ipad3 or am i wrong? (Thats why i'm thinking that its not a solution to his problem).

well, the AirParrot software mentioned in this thread is actually doing this if I understood their website correctly.

ahh ok ... didn't read it

just curious,have u guys read this unofficial protocol?

It seems mirrioring is base on h264 compression. which airserver,airparrot,reflection have all implemented that feature.

Maybe we can do some reverse-engenering?

do it . Thx for the link - i'll try to improve photo and video support based on that one.

Quote:AirParrot works by encoding your display output into H.264 video, meaning you'll likely see some compression artifacts or lag depending on whether you've prioritized speed or image quality in the preferences.

Quote:Screen mirroring is achieved by transmitting an H.264 encoded video stream over a TCP connection. This stream is packetized with a 128-byte header. AAC-ELD audio is sent using the AirTunes protocol. As for the master clock, it is synchronized using NTP.

Moreover, as soon as a client starts a video playback, a standard AirPlay connection is made to send the video URL, and mirroring is stopped. This avoids decoding and re-encoding the video, which would incur a quality loss.

As I understand it both Apple's AirPlay Mirroring and AirParrot AirPlay Screen Mirroring achieve it this the same way, as described in this unofficial AirPlay Protocol Specification.

By in near-real time capturing the screen, encoding it as H.264 video, and sending that video to a AirPlay device such as the Apple TV.


Would be nice if XBMC could receive this Apple's AirPlay Mirroring and AirParrot AirPlay Screen Mirroring from an iPhone or iPad

XBMC does not need to be able send AirPlay Mirroring to achieve that. To send, XBMC would have to capture and encode to H.264
