Trying to get bytes and append using NSMutableData for a video through Asset Library gives memory full error

Question

Hi,

I’m trying to upload a video of size 100MB through Asset Library. But when i try to use "- (NSUInteger)getBytes:(uint8_t )buffer fromOffset:(long long)offset length:(NSUInteger)length error:(NSError *)error” of ALAssetRepresentation i get memory full error. I also need to put the data in buffer to NSData. How can i achieve that?
