Struct CodecPreferences 

pub struct CodecPreferences {
    pub prefer: Vec<String>,
    pub exclude: Vec<String>,
    pub no_hardware: bool,
    pub boost: i32,
}

User preferences for codec selection — pass to the registry’s resolve methods to bias / restrict the choice.

Fields

exclude: Vec<String>

Implementation names to skip entirely.

no_hardware: bool

Forbid hardware-accelerated impls.

boost: i32

Boost amount for prefer impls (subtracted from priority).
