AVFoundation video capture won't save - objective-c

Question

I am using AVFoundation to capture video. All seems to be well in my app until I get to here:
- (void)captureOutput:(AVCaptureFileOutput *)captureOutput
didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL
fromConnections:(NSArray *)connections
error:(NSError *)error
{
NSLog(#"didFinishRecordingToOutputFileAtURL - enter");
BOOL RecordedSuccessfully = YES;
if ([error code] != noErr)
{
// A problem occurred: Find out if the recording was successful.
id value = [[error userInfo] objectForKey:AVErrorRecordingSuccessfullyFinishedKey];
if (value)
{
RecordedSuccessfully = [value boolValue];
}
}
if (RecordedSuccessfully)
{
//----- RECORDED SUCESSFULLY -----
NSLog(#"didFinishRecordingToOutputFileAtURL - success");
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:outputFileURL])
{
[library writeVideoAtPathToSavedPhotosAlbum:outputFileURL
completionBlock:^(NSURL *assetURL, NSError *error)
{
if (error)
{
}
}];
}
[library release];
}
}
When running it on a device I receive the "didFinishRecordingToOutputFileAtURL - success" message, and then it crashes and I get this error:
Video /private/var/mobile/Applications/EDC62CED-3710-45B2-A658-A2FE9238F517/tmp/output.mov cannot be saved to the saved photos album: Error Domain=NSOSStatusErrorDomain Code=-12950 "Movie could not be played." UserInfo=0xe6749b0 {NSLocalizedDescription=Movie could not be played.}
I haven't been able to find a whole lot of information about this anywhere and am not really sure what's going on.
Here's the code with the temporary output URL:
NSString *outputPath = [[NSString alloc] initWithFormat:#"%#%#", NSTemporaryDirectory(), #"output.mov"];
NSURL *outputURL = [[NSURL alloc] initFileURLWithPath:outputPath];
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:outputPath])
{
NSError *error;
if ([fileManager removeItemAtPath:outputPath error:&error] == NO)
{
//Error - handle if requried
}
}
[outputPath release];
//Start recording
[movieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self];
[outputURL release];
I've already tried releasing the outputURL elsewhere after it saves, and that didn't help, so I don't think that's it.

Answer 1

I figured this out. I was an idiot and kept overlooking the fact that I didn't actually connect the video input to the capture session. Whoops.
