Settings for H264 Encoders.

Fields

bit_rate: Option<u32>

Target bits per second for encoded stream. If omitted, interpreted as 200,000.

frame_rate: Option<u32>

Target frames per second for encoded stream. If omitted, interpreted as 30.

gop_size: Option<u32>

Number of pictures per keyframe. Setting to 0 will disable key frame encoding, except for if force_key_frame is set to true. If omitted, interpreted as 8.

variable_frame_rate: Option<bool>

Whether to enable frame rate adjustments in order to meet target bitrate. If omitted, interpreted as false.

min_frame_rate: Option<u32>

Lowest frame rate allowed if variable_frame_rate is enabled. If omitted, interpreted as 10.

force_key_frame: Option<bool>

If true, next frame encoded will be a key frame. If omitted, interpreted as false.

quantization_params: Option<H264QuantizationParameters>

Allow customization of quantization parameters for encoding. Each frame submitted after setting this will use the new values. If omitted, no change from encoder defaults is made.

Trait Implementations

impl Clone for H264EncoderSettings

fn clone(&self) -> H264EncoderSettings

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for H264EncoderSettings

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

Formats the value using the given formatter.

impl<D> Decode<H264EncoderSettings, D> for H264EncoderSettings

where D: ResourceDialect,

fn new_empty() -> H264EncoderSettings

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for H264EncoderSettings

fn default() -> H264EncoderSettings

Returns the “default value” for a type.

impl<D> Encode<H264EncoderSettings, D> for &H264EncoderSettings

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for H264EncoderSettings

fn eq(&self, other: &H264EncoderSettings) -> 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 TypeMarker for H264EncoderSettings

type Owned = H264EncoderSettings

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for H264EncoderSettings

type Borrowed<'a> = &'a H264EncoderSettings

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<H264EncoderSettings as TypeMarker>::Owned, ) -> <H264EncoderSettings as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
