The user is in reality pressing down at a given time and up at a given time, but the program gets a distorted version of this interaction which therefore limits the kinds of things you can do with the remote.

They will be triggered if you let the fast forward or fast backward button down during one or two seconds. _______________________________________________ Do not post admin requests to the list.

This email sent to site_archiver@lists.apple.com I have not tried under darwin with the IR remote, but I would expect that if you use the APIs from TN2187 (http://developer.apple.com/technotes/tn2007/tn2187.html ) you can get the raw HID events before they are sent on to the system. This assumes a 10.5 requirement for whatever application you are writing. What do you mean by limit the API? I'm pretty sure iTunes and QuickTimes are using thoses events to implements fast forward/backward functions. Indeed, I do it too in a video player I wrote and it works pretty well. I'm able to start a fast forward if the user lets the fast forward button pressed and to stop it when it releases it. Thank you for the tip, I will try that as a last resort, but using the raw button press/release events would make a higher quality result. Are those just not available? If not, do you have any idea on why Apple would limit the API in that way? I have an application that uses the Apple remote that is not working optimally in my situation because of the filtering of events Apple seems to do before passing the events along. I would prefer to get the raw button press/release events with no filtering but haven't been able to find out how to do it. I am using IOHIDDeviceInterface122 and IOHIDQueueInterface and some related calls to obtain the events. I have attempted to use "page 0xc" of the IR interface but that didn't seem to do anything useful. As an example of the unwanted filtering: When I press/release "increase/decrease volume", I get the press/release events as they physically happened (my desired behavior); when I press "fast-forward/reverse", I only get a press event upon a physical release and only if I do it in a certain amount of time (which limits the usefulness of my application). In iTunes you can hold down "fast-forward" and it works as expected, so it is getting more information than I'm able to get so far. Thanks for any help! This email sent to tnorton@apple.com smime.p7s
