Enum Hardware 

pub enum Hardware {
    Prefer,
    Require,
    Off,
}

Whether a codec may, must, or must not use dedicated hardware — for decoding and for encoding alike.

Hardware is faster, cooler, and kinder to a laptop battery; software is predictable, identical from one GPU vendor to the next, and the way round a hardware codec that is busy or misbehaving. Either way the codec is the operating system’s for H.264 — Apple’s software H.264 encoder is still Apple’s, licence and all.

Variants

Prefer

Hardware where the machine has it, software where it does not.

Require

Hardware or nothing: a clear refusal rather than a quiet slow path.

Off

Software throughout.
