Attributes common to ADΔER transcode process

Fields

state: VideoState

The current state of the video transcode

display_frame_features: Frame

The current instantaneous display frame with the features drawn on it

instantaneous_view_mode: FramedViewMode

The current view mode of the instantaneous frame

event_sender: Sender<Vec<Event>>

Channel for sending events to the encoder

encoder: Encoder<W>

The object that takes in ADDER events, potentially transforms them in some way, and writes them somewhere

encoder_type: EncoderType

The type of encoder being used (e.g., compressed or raw)

Implementations

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

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

👎Deprecated since 0.3.4: please use update_crf or update_quality_manual instead

Set the positive contrast threshold

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

👎Deprecated since 0.3.4: please use update_crf or update_quality_manual instead

Set the negative contrast threshold

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

Set the number of rows to process at a time (in each thread)

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

Set the time parameters for the video.

These parameters, in conjunction, determine the temporal resolution and maximum transcode accuracy/quality.

Arguments

• tps: ticks per second
• ref_time: reference time in ticks.
• delta_t_max: maximum time difference between events of the same pixel, in ticks

returns: Result<Video<W>, Box<dyn Error, Global>>

pub fn write_out( self, source_camera: Option<SourceCamera>, time_mode: Option<TimeMode>, pixel_multi_mode: Option<PixelMultiMode>, adu_interval: Option<usize>, encoder_type: EncoderType, encoder_options: EncoderOptions, write: W ) -> Result<Self, SourceError>

Write out the video to a file.

Arguments

• source_camera: the type of video source
• time_mode: the time mode of the video
• write: the output stream to write to

pub fn end_write_stream(&mut self) -> Result<Option<W>, SourceError>

Close and flush the stream writer.

Errors

Returns an error if the stream writer cannot be closed cleanly.

pub fn get_ref_time(&self) -> u32

Get ref_time

pub fn get_delta_t_max(&self) -> u32

Get delta_t_max

pub fn get_tps(&self) -> u32

Get tps

pub fn update_delta_t_max(&mut self, dtm: u32)

Set a new value for delta_t_max

pub fn update_detect_features( &mut self, detect_features: bool, show_features: ShowFeatureMode, feature_rate_adjustment: bool, feature_cluster: bool )

Set a new bool for feature_detection

pub fn update_adder_thresh_pos(&mut self, c: u8)

👎Deprecated since 0.3.4: please use update_crf or update_quality_manual instead

Set a new value for c_thresh_pos

pub fn update_adder_thresh_neg(&mut self, _c: u8)

👎Deprecated since 0.3.4: please use update_crf or update_quality_manual instead

Set a new value for c_thresh_neg

pub 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

pub fn get_encoder_options(&self) -> EncoderOptions

Get the encoder options

pub fn get_time_mode(&self) -> TimeMode

Get the time mode of the video

pub fn update_quality_manual( &mut self, c_thresh_baseline: u8, c_thresh_max: u8, delta_t_max_multiplier: u32, c_increase_velocity: u8, feature_c_radius: f32 )

Manually set the parameters dictating quality

pub fn get_event_size(&self) -> u8

Get the size of the raw events (in bytes)
