iOS实现视频压缩上传实例代码

之前写过图片上传PHP服务器，今天把接口稍微改了一下，把视频上传的代码贴出来，目前上传功能已经调通，视频的压缩代码上似乎并不完善，后续会完善压缩部分的代码；

- (void)convertVideoWithURL:(NSURL *)url
{
  NSDate *date = [NSDate date];
  NSDateFormatter *dateformatter = [[NSDateFormatter alloc]init];
  [dateformatter setDateFormat:@"YYYY-MM-dd-HH-mm-ss"];
  NSString *dateName = [dateformatter stringFromDate:date];
  NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).firstObject;
  NSString *pathName = [path stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.mp4",dateName]];
  NSLog(@"沙盒：%@",pathName);
  //转码配置
  AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
  AVAssetExportSession *exportSession= [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetMediumQuality];
  exportSession.shouldOptimizeForNetworkUse = YES;
  exportSession.outputURL = [NSURL fileURLWithPath:pathName];
  exportSession.outputFileType = AVFileTypeMPEG4;
  [exportSession exportAsynchronouslyWithCompletionHandler:^{
    int exportStatus = exportSession.status;
    switch (exportStatus)     {
      case AVAssetExportSessionStatusFailed:
      {
        // log error to text view
        NSError *exportError = exportSession.error;
        NSLog (@"AVAssetExportSessionStatusFailed: %@", exportError);
        [SVProgressHUD showErrorWithStatus:@"视频压缩失败"];
        [SVProgressHUD dismissWithDelay:1.0];
        break;
      }
      case AVAssetExportSessionStatusCompleted:
      {
        self.videoData = [NSData dataWithContentsOfFile:pathName];

        [[NetTool shareDL]upLoadVideoWithURL:@"http://192.168.1.102/php/image.php" paremeter:nil data:self.videoData videoName:[NSString stringWithFormat:@"%@.mp4",dateName] progress:^(NSProgress * _Nonnull uploadProgress) {

          [SVProgressHUD showProgress:1.0*uploadProgress.completedUnitCount/uploadProgress.totalUnitCount status:@"正在上传"];
          NSLog(@"正在上传%f%%",(1.0*uploadProgress.completedUnitCount/uploadProgress.totalUnitCount)*100);

        } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
          [SVProgressHUD showSuccessWithStatus:@"上传成功"];
          [SVProgressHUD dismissWithDelay:1.0];
        } fail:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
          [SVProgressHUD showErrorWithStatus:@"上传失败"];
          [SVProgressHUD dismissWithDelay:1.0];
        }];

      }
    }
  }];
}

[manager POST:url parameters:parameter constructingBodyWithBlock:^(id _Nonnull formData) {
    [formData appendPartWithFileData:videoData name:@"upimage" fileName:videoName mimeType:@"video/mp4"];
  } progress:^(NSProgress * _Nonnull uploadProgress) {
    progress(uploadProgress);
  } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
    success(task,responseObject);
  } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    fail(task,error);
  }];
