H264 codec settings.

Fields

width_pixels: i32

Required. The width of the video in pixels. Must be an even integer. Valid range is [320, 1920].

height_pixels: i32

Required. The height of the video in pixels. Must be an even integer. Valid range is [180, 1080].

frame_rate: f64

Required. The target video frame rate in frames per second (FPS). Must be less than or equal to 60. 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. Minimum value is 10,000.

• For SD resolution (< 720p), must be <= 3,000,000 (3 Mbps).
• For HD resolution (<= 1080p), must be <= 15,000,000 (15 Mbps).

allow_open_gop: bool

Specifies whether an open Group of Pictures (GOP) structure should be allowed or not. 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 [bitrate_bps][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings.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 [vbv_size_bits][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings.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 [gop_frame_count][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings.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 (default)
• high

The available options are FFmpeg-compatible Profile Options. Note that certain values for this field may cause the transcoder to override other fields you set in the [H264CodecSettings][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings] message.

tune: String

Enforces the specified codec tune. The available options are FFmpeg-compatible Encode Options Note that certain values for this field may cause the transcoder to override other fields you set in the [H264CodecSettings][google.cloud.video.livestream.v1.VideoStream.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

Formats the value using the given formatter.

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>

where Self: Sized,

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.

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

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.
