Ipad and Qlab

[nizer]

I want to use my ipad with Qlab. I want to run a APP on the iPad and
have the resulting screen available to my macbook pro as a qlab
screen.

or...

I want to project the output of my ipad to a projector and switch
between it and my mac without having to unplug.

Ideas....?

Yup.  It's called a switcher. The most basic one i'd recommend is a PresentationPRO.  (Not the PresentationPRO II)

I think this is the reverse of what Mark is trying to do. He wants the output from the iPad to go through the Mac

Maybe I'm misunderstanding "available to my macbook pro as a qlab screen" then... I thought that meant something QLab could _output_ to.

hmm - we read this in entirely opposite ways - but your reading totally makes sense - maybe even more sense (since I know Mark's show)  he'll have to tell us which way he had in mind....

this is somewhat related, depending on which version of the interpretation one reads --- i had the thought last night that the mac os x "mirror displays" mode 

could actually be useful if the user was allowed to define the area of a larger screen that would be mirrored on a smaller (second) screen. any thoughts ?? 

this would allow the user to use the full (larger) screen with a mask-outline-box that delineates the area of the larger screen that is mirrored to the second display screen. 

this is entirely like the ios app screencaster except that instead of an airdisplay it's actually on the corevideo layer ?? ie mirror mode would be useful. any thoughts please ... 

i read this thread's original post to be- how can we use an ios device and something like airdisplay to send display information through qlab. ie, the ios device outputs 

something like a wifi camera that the qlab camera cue can use and qlab coordinates this camera cue to a particular video output screen, etc.

Thanks for all the input on this topic.

Here is what I am trying to accomplish. I have a iPad with a iPad ONLY
app running on it. I want the content of the iPad screen to appear in
cue lab as a video input/screen. Right now I am accomplishing this by
putting my iPad in front of my macbookpro and having the built in
iSight camera film the screen. Kind of a lame solution.

I was considering using a video switcher and a dmx relay to switch
from my mac to my ipad screens going to the projector but that is also
kinda defeating the whole purpose. Plus more crap to haul around.

I am hoping the developer will make a mac version of this app not just
a ios version.

The aproach that comes to mind would be to  use something like the the Blackmagic Intensity Extreme thunderbolt interface with the iPad HDMI adapter to get video from the iPad into the mac.  I'm not sure if Qlab can see that interface to take video from - hopefully others can chime in on that - if not it can probably be done with a custom quartz composer patch.

i've used an ADVC110 -- http://www.grassvalley.com/products/advc110 -- to get a composite camera signal into qlab via the camera cue ...... this works with the existing camera cue because it is a firewire 400 box .. this would definitely get the ipad output into qlab via the ipad AV breakout cable (composite) ..... 

[Andy Dolph]

Will the iPad output whatever is on the screen through the composite out? or just videos?  (I have an iPad 1 so I can't test anyway....)

yes -- from iOS 5 i believe the mirroring was supposed to be full-screen regardless of app, content, or plug-flavor -------- but i haven't had that experience. some apps don't seem to work at all .. some apps only work when PLAY is engaged, etc. i do have all three flavors of connector (composite, hdmi, vga) so if i get a minute tonight i will try it out .......

Doesn't the Apple TV do full app mirroring? Could an HDMI signal be pulled from the Apple TV and somehow reinserted back into Qlab perhaps as a Camera Cue? Super spitballing here. 

[dan howarth]

these were all a google away-- great articles about what works with iOS screen mirroring.

https://discussions.apple.com/thread/2780800?start=0&tstart=0

and most essential to our topic was this one --- 

http://www.tuaw.com/2011/04/01/ipad-2-video-out-part-2-capturing-in-higher-definition/

the ipad 2 & iphone 4s (and really nothing else unless jailbroken) will do screen mirroring -pretty well- including showing the iOS interface and more or less what apps look like. vga or hdmi. 

when a video is played it is quite likely that the ipad / iphone screen will go dark, ie only one output is playing -- the one that is plugged into something else. 

and yes chris B with the apple tv thing -- that's great too -- http://www.apple.com/appletv/airplay.html ----- i'm kinda curious about this one ---- 

re: camera cue .. i wonder how much latency will build up getting this signal to happen .. wifi output chip from ipad - apple tv wifi thru to hdmi out - to blackmagic intensity hdmi in - 

thunderbolt to computer - quartz composer video hijack - qlab - back out to ? .... that seems like a lot. to go wrong, too. 

brings to mind that the previous thread's wisdom about ... not trying to do too much with lots of software and hardware if .. a simple few cables and a human can do the same magic.

Eureka!!!!! LOOK WHAT I FOUND!

It works :-). I have not had time yet to see if I can get it to be a
"camera" cue. But I can just have it on the projector screen and close
all the other videos.

No hacking or cables required.

nice work mark i am going to try this out too

Hi all,


I see that the post has been snoozing for a while... anyone happy to share any experience with this or similar solutions?


Cheers,

Freddy

Works great been totally happy with it.

Recently picked up an app called "AirServer" that allows me to receive the mirrored screen of an iPad or iPhone 4S (or later) on either mac or PC. This has worked very well for product demos and instances where execs want to present wirelessly from their (now nearly ubiquitous) corporate iPads. Caveats: It's up to the user of the phone/pad user to make the connection; and, there is no way on the mac/PC to choose who gets on screen, which can result in multiple screen madness (I've emailed the developer about the possibility of adding some kind of chooser function).
I've not tried passing the result through QLab, but I imagine it could be siphoned...
I believe Apple TV offers the same or similar functionality out of the box.
