Added (1). The cracking and whining noise. See video.

Sounds like a bearing going bad on one of the drive belt systems (alternator, AC unit, belt tensioner, power steering pump)

What CB said. Take the belt off and check every pulley that turns.

I hear hydraulic lifter noise but the whine isn't good. If that isn't the power steering pump you have a serious problem with the cam advance mechanism and need to go to the dealer as soon as possible. Try taking the drive belts off and see if the whine is gone. Don't just keep driving until the motor won't run.
