DecodeCapabilities

Struct DecodeCapabilities 

Source
pub struct DecodeCapabilities {
    pub backend_available: bool,
    pub hardware_decode_available: bool,
    pub known_decoder_names: Vec<String>,
}
Expand description

Lightweight capability information about the decode backend.

Obtained via discover_decode_capabilities(). This is a snapshot; the underlying system state may change after construction (e.g., a GPU driver crash).

§Examples

use nv_media::DecodeCapabilities;

let caps = nv_media::discover_decode_capabilities();
if !caps.backend_available {
    eprintln!("Media backend not compiled in or failed to initialise");
} else if caps.hardware_decode_available {
    println!("Hardware decoders: {:?}", caps.known_decoder_names);
}

Fields§

§backend_available: bool

Whether the media backend is compiled in and initialized successfully.

When false, the remaining fields are meaningless — the backend is absent or failed to initialize. Operators can use this to distinguish a misbuild/misconfiguration from a genuine no-hardware condition (backend_available == true but hardware_decode_available == false).

§hardware_decode_available: bool

Whether at least one hardware video decoder was detected in the backend registry. Only meaningful when backend_available is true.

§known_decoder_names: Vec<String>

Names of known hardware video decoder elements discovered in the backend registry. Empty when hardware_decode_available is false or the backend is not compiled in.
