我有一个简单的小 osx 应用程序,它只启动一个 IKPictureTaker,然后将生成的图片保存为 .tiff 文件。一切似乎都很好,但是每次我拍照时都会反复出现此错误:
2009-11-10 12:25:38.890 Take A Picture[855:9c23] *** QTCaptureSession warning: Session received the following error while decompressing video: Error Domain=NSOSStatusErrorDomain Code=-67441 "Operation could not be completed. (OSStatus error -67441.)". Make sure that the formats of all video outputs are properly configured.
代码非常简单:
- (void)awakeFromNib
{
IKPictureTaker *sharedPictureTaker = [IKPictureTaker pictureTaker];
[sharedPictureTaker setValue:[NSNumber numberWithBool:YES] forKey:IKPictureTakerShowEffectsKey];
[sharedPictureTaker beginPictureTakerWithDelegate:self didEndSelector:@selector(pictureTakerDidEnd:returnCode:contextInfo:) contextInfo:nil];
}
- (void) pictureTakerDidEnd:(IKPictureTaker *) picker
returnCode:(NSInteger) code
contextInfo:(void*) contextInfo
{
NSImage *image = [picker outputImage];
NSString *folder = @"/Users/Mike/Library/Application Support/file.tiff";
folder = [folder stringByExpandingTildeInPath];
[[image TIFFRepresentation] writeToFile:@"~/Library/Application Support/file2.tiff" atomically:NO];
}
