Video upload on Amazon S3 in iphone application - ios

Question

I am uploading video to Amazon S3 from iphone application. Earlier it was uploading fine but now all of a sudden it has stopped uploading the video and crashes the app. Below is the code for video upload
if(![ACCESS_KEY_ID isEqualToString:#"CHANGE ME"]
&& self.s3 == nil)
{
// Initial the S3 Client.
self.s3 = [[[AmazonS3Client alloc] initWithAccessKey:ACCESS_KEY_ID withSecretKey:SECRET_KEY] autorelease];
self.s3.endpoint = [AmazonEndpoints s3Endpoint:US_WEST_2];
}
NSString *videoName =[NSString stringWithFormat:#"%#",titleTextField.text];
NSString *trimmedString = [videoName stringByTrimmingCharactersInSet:
[NSCharacterSet whitespaceCharacterSet]];
NSLog(#"name %#",trimmedString);
S3PutObjectRequest *por = [[[S3PutObjectRequest alloc] initWithKey:trimmedString
inBucket:[Constants pictureBucket]] autorelease];
por.contentType = #"movie/mp4";
por.data= videoData;
S3PutObjectResponse *putObjectResponse = [self.s3 putObject:por];
Here is the crash log
Terminating app due to uncaught exception 'AmazonServiceException', reason: '(null)' * First throw call stack: (0x2f370f53 0x399db6af 0xb6119 0xc39b3 0xc2f4d 0x533b9 0x5366f 0x2fd53e27 0x3a002c1d 0x3a002b8f 0x3a000c90) libc++abi.dylib: terminating with uncaught exception of type AmazonServiceException

Answer 1

Try setting the content length field and locally declaring the S3 client:
AmazonS3Client *s3 = [[AmazonS3Client alloc] initWithAccessKey:ACCESS_KEY_ID withSecretKey:SECRET_KEY]; //auto release deprecated, and not necessary with local declaration
s3.endpoint = [AmazonEndpoints s3Endpoint:US_WEST_2];
//post full video
por = [[S3PutObjectRequest alloc] initWithKey:generatedString inBucket:#"dormpicbucket"];
por.contentType = #"video/mp4";
por.data = capturedMovie;
por.delegate = self;
[por setDelegate:self];
por.contentLength = [capturedMovie length];
[s3 putObject:por];
Also make sure to debug this: [Constants pictureBucket] because it looks like youre using the sample/tutorial code from aws docs almost explicitly lol.
