¿Cómo guardar videos grabados en un álbum de fotos?

Question

El siguiente código es para guardar la imagen tomada de la cámara en el álbum de fotos.

if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
image = [info objectForKey:UIImagePickerControllerEditedImage];
UIImageWriteToSavedPhotosAlbum(image, self,
@selector(image:finishedSavingWithError:contextInfo:),
nil);
}

Cómo guardar video recodificado en photoAlbum?

Answer 1

Pruebe el código siguiente

- (void)saveVideo:(NSURL *)videoUrl {
NSData *videoData = [NSData dataWithContentsOfURL:videoUrl];
[videoData writeToFile:@"YOUR_PATH_HERE" atomically:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *type = [mediaDict objectForKey:UIImagePickerControllerMediaType];
if ([type isEqualToString:(NSString *)kUTTypeVideo] ||
[type isEqualToString:(NSString *)kUTTypeMovie]) { // movie != video
NSURL *videoURL [mediaDict objectForKey:UIImagePickerControllerMediaURL];
[self saveVideo:videoUrl];
}
}

o puede intentar esto también Guardar el video en el directorio de documentos es el siguiente

 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *tempPath = [documentsDirectory stringByAppendingFormat:@"/vid1.mp4"];
BOOL success = [videoData writeToFile:tempPath atomically:NO];
[picker dismissModalViewControllerAnimated:YES];
}

Answer 2

Verifique el código siguiente ...

 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:@"public.movie"]){
// Saving the video / // Get the new unique filename
NSString *sourcePath = [[info objectForKey:@"UIImagePickerControllerMediaURL"]relativePath];
UISaveVideoAtPathToSavedPhotosAlbum(sourcePath,nil,nil,nil);
}

Answer 3

- (void)saveMovieToCameraRoll
{
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:movieURL
completionBlock:^(NSURL *assetURL, NSError *error) {
if (error)
[self showError:error];
else
[self removeFile:movieURL];
dispatch_async(movieWritingQueue, ^{
recordingWillBeStopped = NO;
self.recording = NO;
[self.delegate recordingDidStop];
});
}];
[library release];
}

Este es el fragmento de código de apple example rosywriter. Sould funciona.

 movieURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@%@", NSTemporaryDirectory(), @"Movie.MOV"]];
[movieURL retain];

Las líneas anteriores para crear el archivo y la ruta del video.

- (void) startRecording
{
dispatch_async(movieWritingQueue, ^{
if ( recordingWillBeStarted || self.recording )
return;
recordingWillBeStarted = YES;
// recordingDidStart is called from captureOutput:didOutputSampleBuffer:fromConnection: once the asset writer is setup
[self.delegate recordingWillStart];
// Remove the file if one with the same name already exists
[self removeFile:movieURL];
// Create an asset writer
NSError *error;
assetWriter = [[AVAssetWriter alloc] initWithURL:movieURL fileType:(NSString *)kUTTypeQuickTimeMovie error:&error];
if (error)
[self showError:error];
});
}

Esta función se usa para comenzar a grabar video en ese archivo movieURL usando avassetwriter.
