iOS拍摄视频，压缩并上传服务器
从本地选择视频，或者用UIImagePickerController录制视频
小编也是第一次做视频上传，参考
http://blog.csdn.net/personsky/article/details/52471354实现的
//选择本地视频 - (void)choosevideo { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;//sourcetype有三种分别是camera，photoLibrary和photoAlbum NSArray *availableMedia = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];//Camera所支持的Media格式都有哪些,共有两个分别是@"public.image",@"public.movie" ipc.mediaTypes = [NSArray arrayWithObject:availableMedia[1]];//设置媒体类型为public.movie [self presentViewController:ipc animated:YES completion:nil]; ipc.delegate = self;//设置委托 } //录制视频 - (void)startvideo { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.sourceType = UIImagePickerControllerSourceTypeCamera;//sourcetype有三种分别是camera，photoLibrary和photoAlbum ipc.cameraDevice = UIImagePickerControllerCameraDeviceFront; NSArray *availableMedia = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];//Camera所支持的Media格式都有哪些,共有两个分别是@"public.image",@"public.movie" ipc.mediaTypes = [NSArray arrayWithObject:availableMedia[1]];//设置媒体类型为public.movie [self presentViewController:ipc animated:YES completion:nil]; ipc.videoMaximumDuration = 30.0f;//30秒 ipc.delegate = self;//设置委托 //在录制视频的界面添加点东西 UIView *BgView = [[UIView alloc] init]; BgView.LYW_X = LYWScreenWidth*0.5 - 150*X6Scale; BgView.LYW_Y = 40*Y6Scale; BgView.LYW_W = 300*X6Scale; BgView.LYW_H = 200*Y6Scale; UILabel *lab = [[UILabel alloc] init]; lab.LYW_X = 0; lab.LYW_Y = 0; lab.LYW_W = 300*X6Scale; lab.LYW_H = 200*Y6Scale; lab.text = @“http://www.jianshu.com/u/0158007b8d17”; lab.numberOfLines = 0; lab.textColor = [UIColor orangeColor]; [BgView addSubview:lab]; ipc.cameraOverlayView = BgView; }
视频录制完成，保存到相册
//完成视频录制，并压缩后显示大小、时长 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *sourceURL = [info objectForKey:UIImagePickerControllerMediaURL]; NSLog(@"%@",[NSString stringWithFormat:@"%f s", [self getVideoLength:sourceURL]]); NSLog(@"%@", [NSString stringWithFormat:@"%.2f kb", [self getFileSize:[sourceURL path]]]); NSURL *newVideoUrl ; //一般.mp4 NSDateFormatter *formater = [[NSDateFormatter alloc] init];//用时间给文件全名，以免重复，在测试的时候其实可以判断文件是否存在若存在，则删除，重新生成文件即可 [formater setDateFormat:@"yyyy-MM-dd-HH:mm:ss"]; newVideoUrl = [NSURL fileURLWithPath:[NSHomeDirectory() stringByAppendingFormat:@"/Documents/output-%@.mp4", [formater stringFromDate:[NSDate date]]]] ;//这个是保存在app自己的沙盒路径里，后面可以选择是否在上传后删除掉。我建议删除掉，免得占空间。 _fileName = [NSString stringWithFormat:@"output-%@.mp4", [formater stringFromDate:[NSDate date]]]; NSURL * url = [info objectForKey:UIImagePickerControllerMediaURL]; NSString * urlStr = [url path]; if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(urlStr)) { //保存视频到相簿，注意也可以使用ALAssetsLibrary来保存 UISaveVideoAtPathToSavedPhotosAlbum(urlStr, self, @selector(video:didFinishSavingWithError:contextInfo:), nil); } [picker dismissViewControllerAnimated:YES completion:nil]; [self convertVideoQuailtyWithInputURL:sourceURL outputURL:newVideoUrl completeHandler:nil]; } #pragma mark - 自定义方法 - (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{ if (error) { NSLog(@"保存视频过程中发生错误，错误信息:%@",error.localizedDescription); } else { NSLog(@"视频保存成功"); _videoUrl = videoPath; NSURL * url = [NSURL fileURLWithPath:videoPath]; // self.dateTimeLab.text = [LYWRegex getCurrentTimes]; //获取视频第一帧 // [self.showBtn setBackgroundImage:[LYWRegex thumbnailImageForVideo:url atTime:1] forState:UIControlStateNormal]; } }
压缩视频并上传给服务器 使用AFN
#pragma mark - 压缩视频 - (void) convertVideoQuailtyWithInputURL:(NSURL*)inputURL outputURL:(NSURL*)outputURL completeHandler:(void (^)(AVAssetExportSession*))handler { AVURLAsset *avAsset = [AVURLAsset URLAssetWithURL:inputURL options:nil]; AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:avAsset presetName:AVAssetExportPresetMediumQuality]; // NSLog(resultPath); exportSession.outputURL = outputURL; exportSession.outputFileType = AVFileTypeMPEG4; exportSession.shouldOptimizeForNetworkUse= YES; [exportSession exportAsynchronouslyWithCompletionHandler:^(void) { switch (exportSession.status) { case AVAssetExportSessionStatusCancelled: NSLog(@"AVAssetExportSessionStatusCancelled"); break; case AVAssetExportSessionStatusUnknown: NSLog(@"AVAssetExportSessionStatusUnknown"); break; case AVAssetExportSessionStatusWaiting: NSLog(@"AVAssetExportSessionStatusWaiting"); break; case AVAssetExportSessionStatusExporting: NSLog(@"AVAssetExportSessionStatusExporting"); break; case AVAssetExportSessionStatusCompleted: NSLog(@"AVAssetExportSessionStatusCompleted"); NSLog(@"%@",[NSString stringWithFormat:@"%f s", [self getVideoLength:outputURL]]); NSLog(@"%@", [NSString stringWithFormat:@"%.2f kb", [self getFileSize:[outputURL path]]]); //UISaveVideoAtPathToSavedPhotosAlbum([outputURL path], self, nil, NULL);//这个是保存到手机相册 _outputURL = outputURL; // [self alertUploadVideo:outputURL]; break; case AVAssetExportSessionStatusFailed: NSLog(@"AVAssetExportSessionStatusFailed"); break; } }]; } -(void)alertUploadVideo:(NSURL*)URL{ CGFloat size = [self getFileSize:[URL path]]; NSString *message; NSString *sizeString; CGFloat sizemb= size/1024; if(size<=1024){ sizeString = [NSString stringWithFormat:@"%.2fKB",size]; }else{ sizeString = [NSString stringWithFormat:@"%.2fMB",sizemb]; } if(sizemb<2){ [self uploadVideo:URL]; } else if(sizemb<=5){ message = [NSString stringWithFormat:@"视频%@，大于2MB会有点慢，确定上传吗？", sizeString]; UIAlertController * alertController = [UIAlertController alertControllerWithTitle: nil message: message preferredStyle:UIAlertControllerStyleAlert]; [alertController addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { [[NSNotificationCenter defaultCenter] postNotificationName:@"refreshwebpages" object:nil userInfo:nil]; [[NSFileManager defaultManager] removeItemAtPath:[URL path] error:nil];//取消之后就删除，以免占用手机硬盘空间（沙盒） }]]; [alertController addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { [self uploadVideo:URL]; }]]; [self presentViewController:alertController animated:YES completion:nil]; }else if(sizemb>5){ message = [NSString stringWithFormat:@"视频%@，超过5MB，不能上传，抱歉。", sizeString]; UIAlertController * alertController = [UIAlertController alertControllerWithTitle: nil message: message preferredStyle:UIAlertControllerStyleAlert]; [alertController addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { [[NSNotificationCenter defaultCenter] postNotificationName:@"refreshwebpages" object:nil userInfo:nil]; [[NSFileManager defaultManager] removeItemAtPath:[URL path] error:nil];//取消之后就删除，以免占用手机硬盘空间 }]]; [self presentViewController:alertController animated:YES completion:nil]; } } #pragma mark - 上传视频 -(void)uploadVideo:(NSURL*)URL{ NSMutableDictionary *dict = [NSMutableDictionary dictionary]; NSData *data = [NSData dataWithContentsOfURL:URL]; dict[@"loanvideo"] = data; dict[@"record_id"] = self.loan_record_id; NSString *uploadVideoUrl = [NSString stringWithFormat:@"%@%@",BaseUrl,@"uploadloanvideo"]; [[NetworkHelper shareInstance] Post:uploadVideoUrl parameter:dict data:data name:@"loanvideo" fileName:_fileName mimeType:@"video/mpeg" success:^(id responseObject) { NSLog(@"视频上传成功"); } failure:^(NSError *error) { NSLog(@"视频上传失败"); }]; }
Demo把视频上传到服务器的代码注释掉了
