AVCaptureConnection orientation

A lenyeg, hogy az AVCaptureConnection-on kell beallitani a videoOrientation-t es nem az AVCaptureSession-on vagy az AVCaptureDevice-on.

Valahogy igy:

for(int i = 0; i < [[captureOutput connections] count]; i++) {

AVCaptureConnection *captureConnection = [[captureOutput connections] objectAtIndex:i];

if([captureConnection isVideoOrientationSupported]) {

[captureConnection setVideoOrientation:[[UIDevice currentDevice] orientation]];

}

}

Fontos viszont, hogy AVCaptureVideoDataOutput connection-jan nem lehet videoOrientation-t (es videoMirrored-et) allitani.

Innen:

Videos on iPhone are recorded on Quicktime format. The Quicktime format always record videos on landscape and insert metadata on the archive with the orientation information (portrait or landscape) on the moment that was recorded.
