Struct DisplayVideoConfig 

pub struct DisplayVideoConfig {
    pub scale: Option<f32>,
    pub format: Option<i32>,
    pub key_frame_interval_secs: Option<u32>,
    pub max_stream_size_bytes: Option<u64>,
    pub bitrate_bps: Option<u32>,
}

Config for the “android.display.video” data source. Unset/0 fields use the producer’s default.

Fields

scale: Option<f32>

Scale applied to each display’s resolution before capture (0.25 = quarter size).

format: Option<i32>

key_frame_interval_secs: Option<u32>

Keyframe interval in seconds. Smaller = snappier seeking, larger trace.

max_stream_size_bytes: Option<u64>

Per-display cap on emitted bytes. On reaching it the stream is torn down with a VideoFrameError (SIZE_CAP_HIT).

bitrate_bps: Option<u32>

Target video encoder bitrate in bits per second. Controls quality vs trace size at a fixed resolution (unlike scale, which changes the resolution). Unset lets the producer pick a default from the (scaled) resolution and frame rate. Maps to MediaFormat.KEY_BIT_RATE.

Implementations

impl DisplayVideoConfig

pub fn scale(&self) -> f32

Returns the value of scale, or the default value if scale is unset.

pub fn format(&self) -> Format

Returns the enum value of format, or the default if the field is unset or set to an invalid enum value.

pub fn set_format(&mut self, value: Format)

Sets format to the provided enum value.

pub fn key_frame_interval_secs(&self) -> u32

Returns the value of key_frame_interval_secs, or the default value if key_frame_interval_secs is unset.

pub fn max_stream_size_bytes(&self) -> u64

Returns the value of max_stream_size_bytes, or the default value if max_stream_size_bytes is unset.

pub fn bitrate_bps(&self) -> u32

Returns the value of bitrate_bps, or the default value if bitrate_bps is unset.

Trait Implementations

impl Clone for DisplayVideoConfig

fn clone(&self) -> DisplayVideoConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DisplayVideoConfig

impl Debug for DisplayVideoConfig

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

Formats the value using the given formatter.

impl Default for DisplayVideoConfig

fn default() -> Self

Returns the “default value” for a type.

impl Message for DisplayVideoConfig

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 DisplayVideoConfig

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