我需要从CMSampleBufferRef中的未压缩图像数据中获取UI Image.我正在使用代码： captureStillImageOutput captureStillImageAsynchronouslyFromConnection:connection completionHandler:^(CMSampleBufferRef imageSampleBuffer, NSE
captureStillImageOutput captureStillImageAsynchronouslyFromConnection:connection
completionHandler:^(CMSampleBufferRef imageSampleBuffer, NSError *error)
{
// that famous function from Apple docs found on a lot of websites
// does NOT work for still images
UIImage *capturedImage = [self imageFromSampleBuffer:imageSampleBuffer];
}
http://developer.apple.com/library/ios/#qa/qa1702/_index.html是imageFromSampleBuffer函数的链接.
但它不能正常工作.
