Capture Video and Audio and write it to server in iPhone

I tried to capture video and write it to following url.I am getting this error.

Code:

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

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

Exception:

Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: '*** -[AVAssetWriter initWithURL:fileType:error:]

invalid parameter not satisfying: [outputURL isFileURL]'

It looks like it's expecting a local file path but in URL format e.g. file://....

from the docs

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

You would then have to manage the upload to your webserver separately.
