AVCapture appendSampleBuffer

Question

I am going insane with this one - have looked everywhere and tried anything and everything I can thinks of.

Am making an iPhone app that uses AVFoundation - specifically

Answer 1

I do it by using CMSampleBufferCreateForImageBuffer() .

OSStatus ret = 0;
CMSampleBufferRef sample = NULL;
CMVideoFormatDescriptionRef videoInfo = NULL;
CMSampleTimingInfo timingInfo = kCMTimingInfoInvalid;
timingInfo.presentationTimeStamp = pts;
timingInfo.duration = duration;

ret = CMVideoFormatDescriptionCreateForImageBuffer(NULL, pixel, &videoInfo);
if (ret != 0) {
    NSLog(@"CMVideoFormatDescriptionCreateForImageBuffer failed! %d", (int)ret);
    goto done;
}
ret = CMSampleBufferCreateForImageBuffer(kCFAllocatorDefault, pixel, true, NULL, NULL,
                                         videoInfo, &timingInfo, &sample);
if (ret != 0) {
    NSLog(@"CMSampleBufferCreateForImageBuffer failed! %d", (int)ret);
    goto done;
}
