Av1Level

Struct Av1Level 

Source
pub struct Av1Level {
    pub level: u8,
    pub max_pic_size: u64,
    pub max_h_size: u32,
    pub max_v_size: u32,
    pub max_display_rate: u64,
    pub max_bitrate_mbps: u32,
}
Expand description

An entry in the AV1 level table.

Level numbers are encoded as major * 10 + minor; e.g., level 5.1 is encoded as 51. The table is derived from the AV1 specification, Annex A.

Fields§

§level: u8

Level code: major * 10 + minor. Level 4.0 → 40, 6.3 → 63.

§max_pic_size: u64

Maximum picture size in pixels (width × height).

§max_h_size: u32

Maximum horizontal picture dimension in pixels.

§max_v_size: u32

Maximum vertical picture dimension in pixels.

§max_display_rate: u64

Maximum display sample rate in samples per second.

§max_bitrate_mbps: u32

Maximum bitrate in Mbps (megabits per second).

Implementations§

Source§

impl Av1Level

Source

pub fn from_code(code: u8) -> Option<Self>

Return the AV1 level entry for the given code (e.g., 20 = level 2.0).

Returns None if the code does not correspond to a defined level.

Source

pub fn select_for( width: u32, height: u32, fps: f32, bitrate_kbps: u32, ) -> Option<Self>

Find the lowest AV1 level sufficient for the specified video parameters.

Returns None if no defined level can accommodate the request.

Source

pub fn level_str(&self) -> String

Return a human-readable level string such as "4.1".
