Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

AVFoundation video capture saving problems

I am trying to capture and then save a video to the Camera Roll using AVFoundation. However, I keep getting an error after the capture finishes while I am trying to save the video that seems to be pretty obscure; I wasn't able to find a whole lot of information about it.

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.}

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'd appreciate any kind of direction anyone could give me on this.
