捕獲視頻和音頻並將其寫入iPhone中的服務器

Question

我試圖捕獲視頻並將其寫入以下url.I出現此錯誤。

代碼：

videoURL = [[NSURL alloc] initWithString:@"http://belterra.webiguide.com/uploadimages/VideoRecord.mpeg4"]; 

_videoWriter = [[AVAssetWriter alloc] initWithURL:videoURL fileType:AVFileTypeQuickTimeMovie 
              error:&error]; 

例外：

Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: '*** -[AVAssetWriter initWithURL:fileType:error:] 
invalid parameter not satisfying: [outputURL isFileURL]' 
    *** Call stack at first throw:

Answer 1

invalid parameter not satisfying: [outputURL isFileURL]'

它看起來像是例如預計在URL格式的本地文件路徑，但file://....

從文檔

Initializes an asset writer for writing to the file identified by a given URL in a format specified by a given UTI.

你將不得不單獨管理上傳到Web服務器。
