All, I'm trying to grab video from a Dazzle Hollywood or an ADVC-55. Over both of these interfaces I can grab video by opening iMovie, selecting the interface and pressing "play". However, when I try to grab video with the QTCaptureDevice interface, I just get a blank screen (iSight and other

Thanks, I'll have a look. BTW, I was able to confirm it is a result of streams. My Java processes do not quit if I pipe their output to null:  NSTask *task = [NSTask new];  [task setLaunchPath:execPath];  [task setCurrentDirectoryPath:_directory];  [task setArguments:arguments];  [task setStandard

I had to convert times from Windows to iOS on a prior project. We finally settled on an around-the-world solution which geolocated our target location, called a web service (geonames.org) to retrieve the TZ database name for that location, and then built the NSTimeZone structure calling [NSTimeZone
