    Crf(u8),
    Cbr(u64),
    Vbr {
        target: u64,
        max: u64,

}

Rate control modes for video encoding.

Variants

Crf(u8)

Constant Rate Factor (quality-based).

Maintains consistent quality across the video. Lower values = higher quality, larger file. Typical range: 18-28 (23 is default for many codecs).

Cbr(u64)

Constant Bitrate (CBR).

Maintains a constant bitrate throughout. Good for streaming with bandwidth constraints. Value in bits per second.

Vbr

Variable Bitrate (VBR).

Allows bitrate to vary based on complexity. Target bitrate in bits per second, with quality factor.

Fields

target: u64

Target average bitrate.

max: u64

Maximum bitrate.

ConstrainedVbr

Constrained Variable Bitrate.

VBR with strict maximum bitrate limits.

Fields

target: u64

Target average bitrate.

max: u64

Maximum bitrate (hard limit).

buffer_size: u64

Buffer size for rate control.

Abr(u64)

Average Bitrate (ABR).

Targets an average bitrate over the entire video.

Implementations

impl RateControlMode

pub fn target_bitrate(&self) -> Option<u64>

Gets the target bitrate for this rate control mode.

pub fn max_bitrate(&self) -> Option<u64>

Gets the maximum bitrate for this rate control mode.

pub fn is_constant_quality(&self) -> bool

Checks if this is a constant quality mode.

pub fn is_bitrate_mode(&self) -> bool

Checks if this is a bitrate-based mode.

Trait Implementations

impl Clone for RateControlMode

fn clone(&self) -> RateControlMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RateControlMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RateControlMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RateControlMode

fn eq(&self, other: &RateControlMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RateControlMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
