Struct google_api_proto::google::cloud::video::livestream::v1::audio_stream::AudioMapping

pub struct AudioMapping {
    pub input_key: String,
    pub input_track: i32,
    pub input_channel: i32,
    pub output_channel: i32,
    pub gain_db: f64,
}

The mapping for the input streams and audio channels.

Fields

input_key: String

Required. The Channel [InputAttachment.key][google.cloud.video.livestream.v1.InputAttachment.key] that identifies the input that this audio mapping applies to. If an active input doesn’t have an audio mapping, the primary audio track in the input stream will be selected.

input_track: i32

Required. The zero-based index of the track in the input stream. All [mapping][google.cloud.video.livestream.v1.AudioStream.mapping]s in the same [AudioStream][google.cloud.video.livestream.v1.AudioStream] must have the same input track.

input_channel: i32

Required. The zero-based index of the channel in the input stream.

output_channel: i32

Required. The zero-based index of the channel in the output audio stream. Must be consistent with the [input_channel][google.cloud.video.livestream.v1.AudioStream.AudioMapping.input_channel].

gain_db: f64

Audio volume control in dB. Negative values decrease volume, positive values increase. The default is 0.

Trait Implementations

impl Clone for AudioMapping

fn clone(&self) -> AudioMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AudioMapping

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

Formats the value using the given formatter.

impl Default for AudioMapping

fn default() -> Self

Returns the “default value” for a type.

impl Message for AudioMapping

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for AudioMapping

fn eq(&self, other: &AudioMapping) -> 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.
