Struct adder_codec_rs::transcoder::source::framed::Framed

pub struct Framed<W: Write + 'static> {
    pub frame_idx_start: u32,
    pub source_fps: f32,
    pub scale: f64,
    /* private fields */
}

Attributes of a framed video -> ADΔER transcode

Fields

frame_idx_start: u32

Index of the first frame to be read from the input video

source_fps: f32

FPS of the input video. Set automatically by Framed::new()

scale: f64

Scale of the input video. Input frames are resized to this scale before transcoding.

Implementations

impl<W: Write + 'static> Framed<W>

pub fn new( input_filename: String, color_input: bool, scale: f64 ) -> Result<Framed<W>, SourceError>

Create a new Framed source

pub fn frame_start(self, frame_idx_start: u32) -> Result<Self, SourceError>

Set the start frame of the source

pub fn auto_time_parameters( self, ref_time: DeltaT, delta_t_max: DeltaT, time_mode: Option<TimeMode> ) -> Result<Self, SourceError>

Automatically derive the ticks per second from the source FPS and ref_time

pub fn get_ref_time(&self) -> u32

Get the number of ticks each frame is said to span

pub fn get_last_input_frame(&self) -> &Frame

Trait Implementations

impl<W: Write + 'static> Source<W> for Framed<W>

fn consume( &mut self, view_interval: u32, thread_pool: &ThreadPool ) -> Result<Vec<Vec<Event>>, SourceError>

Get pixel-wise intensities directly from source frame, and integrate them with ref_time (the number of ticks each frame is said to span)

fn crf(&mut self, crf: u8)

Set the Constant Rate Factor (CRF) quality setting for the encoder. 0 is lossless, 9 is worst quality.

fn get_video_mut(&mut self) -> &mut Video<W>

Get a mutable reference to the Video object associated with this Source.

fn get_video_ref(&self) -> &Video<W>

Get an immutable reference to the Video object associated with this Source.

fn get_video(self) -> Video<W>

Get the Video object associated with this Source, consuming the Source in the process.

fn get_input(&self) -> Option<&Frame>

fn get_running_input_bitrate(&self) -> f64

Get the last-calculated bitrate of the input (in bits per second)

impl<W: Write + 'static> VideoBuilder<W> for Framed<W>

fn contrast_thresholds(self, c_thresh_pos: u8, _c_thresh_neg: u8) -> Self

Set both the positive and negative contrast thresholds

fn crf(self, crf: u8) -> Self

Set the Constant Rate Factor (CRF) quality setting for the encoder. 0 is lossless, 9 is worst quality.

fn quality_manual( self, c_thresh_baseline: u8, c_thresh_max: u8, delta_t_max_multiplier: u32, c_increase_velocity: u8, feature_c_radius_denom: f32 ) -> Self

Manually set the parameters dictating quality

fn c_thresh_pos(self, c_thresh_pos: u8) -> Self

👎Deprecated since 0.3.4: please use crf or quality_manual instead

Set the positive contrast threshold

fn c_thresh_neg(self, c_thresh_neg: u8) -> Self

👎Deprecated since 0.3.4: please use crf or quality_manual instead

Set the negative contrast threshold

fn chunk_rows(self, chunk_rows: usize) -> Self

Set the chunk rows

fn time_parameters( self, tps: DeltaT, ref_time: DeltaT, delta_t_max: DeltaT, time_mode: Option<TimeMode> ) -> Result<Self, SourceError>

Set the time parameters

fn write_out( self, source_camera: SourceCamera, time_mode: TimeMode, encoder_type: EncoderType, encoder_options: EncoderOptions, write: W ) -> Result<Box<Self>, SourceError>

Set the Encoder

fn show_display(self, show_display: bool) -> Self

Set whether or not the show the live display

fn detect_features( self, detect_features: bool, show_features: ShowFeatureMode ) -> Self

Set whether or not to detect features, and whether or not to display the features
