H264 codec settings.

Fields

width_pixels: i32

The width of the video in pixels. Must be an even integer. When not specified, the width is adjusted to match the specified height and input aspect ratio. If both are omitted, the input width is used.

For portrait videos that contain horizontal ASR and rotation metadata, provide the width, in pixels, per the horizontal ASR. The API calculates the height per the horizontal ASR. The API detects any rotation metadata and swaps the requested height and width for the output.

height_pixels: i32

The height of the video in pixels. Must be an even integer. When not specified, the height is adjusted to match the specified width and input aspect ratio. If both are omitted, the input height is used.

For portrait videos that contain horizontal ASR and rotation metadata, provide the height, in pixels, per the horizontal ASR. The API calculates the width per the horizontal ASR. The API detects any rotation metadata and swaps the requested height and width for the output.

frame_rate: f64

Required. The target video frame rate in frames per second (FPS). Must be less than or equal to 120. Will default to the input frame rate if larger than the input frame rate. The API will generate an output FPS that is divisible by the input FPS, and smaller or equal to the target FPS. See Calculating frame rate for more information.

bitrate_bps: i32

Required. The video bitrate in bits per second. The minimum value is 1,000. The maximum value is 800,000,000.

pixel_format: String

Pixel format to use. The default is yuv420p.

Supported pixel formats:

• yuv420p pixel format
• yuv422p pixel format
• yuv444p pixel format
• yuv420p10 10-bit HDR pixel format
• yuv422p10 10-bit HDR pixel format
• yuv444p10 10-bit HDR pixel format
• yuv420p12 12-bit HDR pixel format
• yuv422p12 12-bit HDR pixel format
• yuv444p12 12-bit HDR pixel format

rate_control_mode: String

Specify the rate_control_mode. The default is vbr.

Supported rate control modes:

• vbr - variable bitrate
• crf - constant rate factor

crf_level: i32

Target CRF level. Must be between 10 and 36, where 10 is the highest quality and 36 is the most efficient compression. The default is 21.

allow_open_gop: bool

Specifies whether an open Group of Pictures (GOP) structure should be allowed or not. The default is false.

enable_two_pass: bool

Use two-pass encoding strategy to achieve better video quality. VideoStream.rate_control_mode must be vbr. The default is false.

vbv_size_bits: i32

Size of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to VideoStream.bitrate_bps.

vbv_fullness_bits: i32

Initial fullness of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to 90% of VideoStream.vbv_size_bits.

entropy_coder: String

The entropy coder to use. The default is cabac.

Supported entropy coders:

• cavlc
• cabac

b_pyramid: bool

Allow B-pyramid for reference frame selection. This may not be supported on all decoders. The default is false.

b_frame_count: i32

The number of consecutive B-frames. Must be greater than or equal to zero. Must be less than VideoStream.gop_frame_count if set. The default is 0.

aq_strength: f64

Specify the intensity of the adaptive quantizer (AQ). Must be between 0 and 1, where 0 disables the quantizer and 1 maximizes the quantizer. A higher value equals a lower bitrate but smoother image. The default is 0.

profile: String

Enforces the specified codec profile. The following profiles are supported:

• baseline
• main
• high (default)

The available options are FFmpeg-compatible. Note that certain values for this field may cause the transcoder to override other fields you set in the H264CodecSettings message.

tune: String

Enforces the specified codec tune. The available options are FFmpeg-compatible. Note that certain values for this field may cause the transcoder to override other fields you set in the H264CodecSettings message.

preset: String

Enforces the specified codec preset. The default is veryfast. The available options are FFmpeg-compatible. Note that certain values for this field may cause the transcoder to override other fields you set in the H264CodecSettings message.

gop_mode: Option<GopMode>

GOP mode can be either by frame count or duration.

Trait Implementations

impl Clone for H264CodecSettings

fn clone(&self) -> H264CodecSettings

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for H264CodecSettings

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

impl Default for H264CodecSettings

fn default() -> Self

Returns the “default value” for a type.

impl Message for H264CodecSettings

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

impl PartialEq for H264CodecSettings

fn eq(&self, other: &H264CodecSettings) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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