objective c - VideoStabilizationSupport in iOS using AVFoundation -

-

i using avfoundation record video in ios app. working correctly. trying enable video stabilization while recording video. here code

i have avcaptureconnetion as

@property(nonatomic, retain) avcaptureconnection *videoconnection;

code enable video stabilization when available

self.videoconnection = [self.videooutput connectionwithmediatype:avmediatypevideo];  if([self.videoconnection isvideomirroringsupported] && self.videodevicetype == videodevicetypefrontcamera) {     [self.videoconnection setvideomirrored:yes];     nslog(@"video mirroring supported"); } else     nslog(@"video mirroring not supported");  if ([self.videoconnection isvideostabilizationsupported]) {     [self.videoconnection enablesvideostabilizationwhenavailable];     nslog(@"video stabilization supported"); } else     nslog(@"!!! video stabilization not supported");

everytime run code , getting below output in xcode console

video mirroring supported !!! video stabilization not supported

why getting video stabilization not supported everytime ? checked on ios 6 & 7 ipod touch 5g , ipad 2, ipad mini.

according appledocs , even so, not source formats , video resolutions supported.

in app , recorded video resoultion 640*480 & mp4 format. causing issue ? if yes, supported resolution & formats ? appledocs not provide list of supported resolutions& formats.

can tell me ? in advance.
