捕获视频和音频并将其写入iPhone中的服务器

Question

我尝试捕获视频并将其写入以下网址。我收到此错误。

代码：

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]'

它看起来像是期望本地文件路径，但是采用URL格式，例如file://....

来自文档

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

然后，您必须单独管理上传到您的网络服务器。
