Enum ChoiceReason 

pub enum ChoiceReason {
    Pinned,
    OnlyAdapter,
    MostGpuEncoders,
    Decodes,
    HighPerformanceOrder,
    PerformancePolicy,
    NoSharedDevice,
}

Why the chosen adapter was taken.

Variants

Pinned

ALPHA2_GPU_ADAPTER names it.

OnlyAdapter

It is the only hardware adapter that renders, or the only adapter at all.

MostGpuEncoders

It encodes more codecs on the GPU than the next one.

Decodes

It encodes as many codecs as the next one, and decodes on the GPU where that one does not.

HighPerformanceOrder

Nothing else tells it from the next one: it comes first in the high-performance order.

PerformancePolicy

ALPHA2_GPU_ADAPTER=performance: the first hardware adapter in the high-performance order.

NoSharedDevice

No adapter could share a device with the video codecs, so decode and encode run without the GPU.
