iPhone 2.2 hides video out code for third-party apps

post #1 of 15
Thread Starter 
An unpublished part of iPhone's latest programming framework lets third-party developers pipe video out to an external device, albeit not without a few catches.

Confirmed by Ars Technica, a programming class in the iPhone SDK known as MPTVOutWindow does essentially what its name implies: it sends video out through the Dock Connector port to an outside source, such as an external screen.

The adaptation is primarily meant for movies but allows any program to export the current contents of the screen, theoretically allowing apps intended for screens larger than the 3.5-inch iPhone LCD.

After testing, however, well-known iPhone developer Erica Sadun notes that touch input is disabled in this mode with current implementations and so prevents using the iPhone as a regular controller for games or presentations. It does recognize accelerometer input for a basic level of control.

The code writer also observes that the programming call appears designed for the phone's landscape view rather than the upright portrait mode for most iPhone apps, forcing developers eager to use the new mode to adjust for the realignment.

But while these limitations have already been discovered, developers have already written basic code and plan to explore the MPTVOutWindow function more in the near future to see what it will do; an example of this is provided below.

It is like the Apple TV, the hardware just keeps getting new abilities ... a new phenomenon for hardware!
From Apple ][ - to new Mac Pro I've used them all.
Long on AAPL so biased

In Jobs' MWSF keynote in January 2007, the iPhone was shown to support video out, in both portrait and landscape mode, and simultaneous touch input.

This is an API for third party apps to use video out. Before that only Apple could use the video out for its in house apps.

It sounds like it's almost completely undocumented, if it is for developer access, it's probably not ready yet.

Yes it sounds like it isn't quite ready yet. I was just pointing out that the iPhone was always capable of video out, there just was no API to make it accessible to developers.

Would be interesting if it will be able to to send a video game to a television with the controls and accelerator working on the iPhones screen.

So what other new unreported code was in 2.2? New in ear headphone support?
That would be nice!

Aggg Apple needs to stop. Are they gonna make iPhone control everything including our souls?

=)
This can open a whole new window in future gaming.

Supposedly, that was a demo model with a video-out card wedged in. Or perhaps not..

Hmmm your iPhone/iPod touch as a controller a WiFi link to an aTV as the video processor and display on your TV....

I'm not too excited about this and I'm not expecting it to turn into anything useful. Call me a pessimist, but I just don't give a crap.

Yet you gave a crap enough to feel the need to post an irrelevant comment. You do care, you just haven't realised yet and are also very narrow-minded, judging by your comment.

I'm just hoping it will allow for a GPS type program to be displayed on an external screen! That would make carputer installations so much nicer...

THINK ABOUT THIS: the ultimate Apple Keynote and Microsoft PowerPoint presentation remote. Computerless. WOW!!!
