I used to get this when outputURL video file name is kept same. This was resolved when i changed the filename .

[solarisis]

changing the file name didn't help me with this error..

NSString* date = [formatter stringFromDate:[NSDate date]]; NSURL* outPutURL = [NSURL fileURLWithPath:[@"~/music/" stringByExpandingTildeInPath]];

outPutURL = [[outPutURL URLByAppendingPathComponent:[@"newname-" stringByAppendingString:date]] URLByAppendingPathExtension:@"mov"]; AVAsset *firstAsset = [AVAsset assetWithURL:self.file]; SDAVAssetExportSession *encoder = [SDAVAssetExportSession.alloc initWithAsset:firstAsset];

ok solved it .. Issue was my previous session which generates the conversion file took time to stop running...
