想實現iPhone手機拍攝一段視頻，上傳到雲端分享給手機好友。

技術實現

視頻壓縮。iPhone拍攝的視頻很大，幾秒鐘就幾十兆檔案了，需要做壓縮，原來考慮用ffmpeg，安裝起來比較複雜，網上也有很多教程，不過在通過appstore審核的時候有一定風險。
首先是點擊開始錄製的代碼：

 

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {                UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];                imagePicker.videoQuality = UIImagePickerControllerQualityTypeIFrame960x540;//視頻品質設定                imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;                imagePicker.delegate = self;                imagePicker.allowsEditing = YES;                imagePicker.videoMaximumDuration = 300.0f;//設定最長錄製5分鐘                imagePicker.mediaTypes = [NSArray arrayWithObject:@"public.movie"];                [self presentViewController:imagePicker animated:YES completion:^{                    }];    }

 

錄製完之後的回調方法：

 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{        NSURL *url = [info objectForKey:UIImagePickerControllerMediaURL];    NSLog(@"------%@",url);        NSString *appDocumentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];        NSURL *uploadURL = [NSURL fileURLWithPath:[[appDocumentPath stringByAppendingPathComponent:[self dateString]] stringByAppendingString:@".mp4"]];        // Compress movie first    [self convertVideoToLowQuailtyWithInputURL:url outputURL:uploadURL];    [self dismissViewControllerAnimated:YES completion:^{            }];    }
