Struct CodecConstraints 

pub struct CodecConstraints {
    pub codec: String,
    pub profile: String,
    pub level: String,
    pub max_width: u32,
    pub max_height: u32,
    pub max_fps: f32,
    pub max_bitrate_kbps: u32,
    pub max_sample_rate: u32,
    pub bit_depths: Vec<u8>,
    pub color_spaces: Vec<String>,
}

A codec-agnostic constraints record used for profile/level validation.

Callers obtain pre-filled instances via the associated constructor functions (e.g., CodecConstraints::av1_main) and then call CodecConstraints::validate_video or CodecConstraints::validate_audio to collect any violations.

Fields

codec: String

Codec name (e.g., "AV1", "VP9", "Opus", "FLAC").

profile: String

Profile name (e.g., "Main", "Profile 0", "Audio").

level: String

Level name (e.g., "4.0", "N/A").

max_width: u32

Maximum picture width in pixels (0 = unlimited).

max_height: u32

Maximum picture height in pixels (0 = unlimited).

max_fps: f32

Maximum frames per second (0.0 = unlimited).

max_bitrate_kbps: u32

Maximum video / audio bitrate in kbps (0 = unlimited).

max_sample_rate: u32

Maximum audio sample rate in Hz (0 = unlimited).

bit_depths: Vec<u8>

Supported bit depths (empty = all).

color_spaces: Vec<String>

Supported colour space names (empty = all).

Implementations

impl CodecConstraints

pub fn av1_main() -> Self

Constraints for AV1 Main profile (4:2:0, 8-bit or 10-bit).

pub fn vp9_profile0() -> Self

Constraints for VP9 Profile 0 (4:2:0, 8-bit).

pub fn opus_audio() -> Self

Constraints for Opus Audio profile.

pub fn flac_standard() -> Self

Constraints for FLAC lossless audio.

pub fn validate_video( constraints: &Self, width: u32, height: u32, fps: f32, bitrate_kbps: u32, ) -> Result<(), Vec<String>>

Validate video stream parameters against constraints.

Returns Ok(()) when all constraints are satisfied, or Err(violations) with a list of human-readable violation messages.

pub fn validate_audio( constraints: &Self, sample_rate: u32, channels: u8, bitrate_kbps: u32, ) -> Result<(), Vec<String>>

Validate audio stream parameters against constraints.

Returns Ok(()) when all constraints are satisfied, or Err(violations) with a list of human-readable violation messages.

Trait Implementations

impl Clone for CodecConstraints

fn clone(&self) -> CodecConstraints

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CodecConstraints

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
