Audio/video encoding is not cheap and it's questionable whether your device and software support hardware encoding. Decode is expensive too, but has better hardware support (which gives you the illusion that "just" video playback is somehow easy). It's really one of the most expensive cpu bound tasks in contemporary computing. It's not too different from evaluating CNNs.
