imageiPhone Firmware 2.2 SDK Reveals Undocumented TV-out Features

Well-known iPhone developer and blogger at Ars Technica, Erica Sadun has discovered that the updated MediaPlayer framework in the recently released iPhone firmware 2.2 Software Development Kit (SDK) offers an option to export video-out live to a connected TV screen. Theoretically the undocumented feature will allow third-party iPhone apps to...

    This would be great if it means I will be able to watch my movies from my iPhone on a TV. This is one of the features that I have been waiting for on the iPhone so hopefully it gets implemented soon.

    Can't you already watch your movies from your iphone to your tv??
    I'm more excited to see if the album artwork via tv out feature comes out as a result of this or possibily even the entire iphone desktop which can show you in coming caller id etc etc..... now that would be super cool.

    Per the first comment, a lot of car audio/dvd systems (i.e. Pioneer AVIC) with the screens do not support watching movies stored on your iPhone. They do for older iPods. This would be huge for owners of these systems and would be ideal if it would allow the access with the current USB cable connections.

    I had that problem with my cable. The standard cable doesn't work for tv out, you have to purchase an iphone cable which set my back a few $$$s
    So do get things straight does this mean that developers will be able to develop apps with tv out features in the current 2.2 software update or will we have to wait for the next update?

    Guys, I see that you all have your iPhones displaying videos on your TV's. I simply want to play music through my TV and can't!

    I've used the lead from my video camera to try and connect the two. 1 lead out of iPhone and 3 into TV. It's a Samsung TV and I have left it on the 'source' that the video camera uses and just whipped out the camera and plugged in my iPhone. Message "No Signal" is presented.

    Any ideas?

    Thanks in advance for any help.

    Men!!!!

    With the device you could use the iPhone/iPod Touch as a Wii!!!! And whatever it means that....

    The iPhone could be easily turn into a control with enough coding...And I think that was the main intention since the beginning...

    Apple is just putting some expectation just to sit and wait what can be done with external developers (without a pay of course)...

    has anyone checked that this still works with iphone OS 4.0 and Xcode 3.2? I just tried running my app which works great in OS 3.1.2 but throws an exception when calling:

    MPVideoView *vidView = [[MPVideoView alloc] initWithFrame: CGRectZero];
    tvoutWindow = [[MPTVOutWindow alloc] initWithVideoView:vidView];

    Exception:
