Problem in saving video to iPhone Library. i have an array of UIImages,and two buttons ,"convertToVideo"&"saveToiPhoneLib"
-(IBAction) convertToVideo
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
NSString *savedVideoPath = [documentsDirectory stringByAppendingPathComponent:@"videoOutput"];
printf(" \n\n\n-Video file == %s--\n\n\n",[savedVideoPath UTF8String]);
[self writeImageAsMovie:imageArray toPath:savedVideoPath size:self.view.frame.size duration:3];
}
here i'm passing the imageArray and savedVideoPath to the function below
-(void)writeImageAsMovie:(NSArray *)array toPath:(NSString*)path size:(CGSize)size duration:(int)duration
{
NSError *error = nil;
AVAssetWriter *videoWriter = [[AVAssetWriter alloc] initWithURL:
[NSURL fileURLWithPath:path] fileType:AVFileTypeQuickTimeMovie
error:&error];
NSParameterAssert(videoWriter);

AVVideoCodecH264, AVVideoCodecKey,
[NSNumber numberWithInt:size.width], AVVideoWidthKey,
[NSNumber numberWithInt:size.height], AVVideoHeightKey,
nil];
AVAssetWriterInput* writerInput = [[AVAssetWriterInput
assetWriterInputWithMediaType:AVMediaTypeVideo
outputSettings:videoSettings] retain];
// NSDictionary *bufferAttributes = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:kCVPixelFormatType_32ARGB], kCVPixelBufferPixelFormatTypeKey, nil];
AVAssetWriterInputPixelBufferAdaptor *adaptor = [AVAssetWriterInputPixelBufferAdaptor
assetWriterInputPixelBufferAdaptorWithAssetWriterInput:writerInput
sourcePixelBufferAttributes:nil];
NSParameterAssert(writerInput);
NSParameterAssert([videoWriter canAddInput:writerInput]);
[videoWriter addInput:writerInput];
//Start a session:
[videoWriter startWriting];
[videoWriter startSessionAtSourceTime:kCMTimeZero];
CVPixelBufferRef buffer = NULL;
//convert uiimage to CGImage.
buffer = [self pixelBufferFromCGImage:[[array objectAtIndex:0] CGImage]];
[adaptor appendPixelBuffer:buffer withPresentationTime:kCMTimeZero];
//Write samples:
......
//Finish the session:
[writerInput markAsFinished];
[videoWriter finishWriting];
}

saving to the iPhone library
-(IBAction) saveToiPhoneLib

printf(" \n\n\n-Video file == %s--\n\n\n",[getImagePath UTF8String]);
UISaveVideoAtPathToSavedPhotosAlbum ( getImagePath,self, @selector(video:didFinishSavingWithError: contextInfo:), nil);
}
- (void) video: (NSString *) videoPath didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo {
NSLog(@"Finished saving video with error: %@", error);
}
but while saving i m getting error message:-
Finished saving video with error: Error Domain=ALAssetsLibraryErrorDomain Code=-3302 "Invalid data" UserInfo=0x1d59f0 {NSLocalizedFailureReason=There was a problem writing this asset because the data is invalid and cannot be viewed or played., NSLocalizedRecoverySuggestion=Try with different data, NSLocalizedDescription=Invalid data}
please let me know my mistake. thanks in advance
