Please give a try with Cross Platform Replay Kit. In the coming version(1.3) we have better support for Vuforia. It records the complete screen at good FPS.

Hi, 

we have just announced an iOS plugin for unity for screen/sound record https://developer.vuforia.com/forum/vuforia-developer-opportunities/development-partner-unity-screensound-recorder-including-mo

Or see demo at  http://youtu.be/e_XCTu_EBUs

As Niklas stated, if you want to save this video on the device, you would need to capture a sequence of screen shots which is an expensive operation.

you could use a AppleTV and stream it. Then caputre the HDMI output.

Hi!

This is the #1 feature request we get....

For our own (youtube) use we built a small rig that enabled us to record the actual running app on a second camera.

For the end user I imagine it would be possible to render the screenshots in succession, but I seriously doubt you would get any framerate worth its salt.

I suppose there might be some clever library on iOS, at least, that could be used to save a framegrab sequence, and then post process the augmentation on top of it. (the augmented coords would need to be recorded separately, and the geometry recreated in the video post process).

Anyone have other good ideas?
