Running state of the video transcode

Fields

plane: PlaneSize

The size of the imaging plane

chunk_rows: usize

The number of rows of pixels to process at a time (per thread)

in_interval_count: u32

The number of input intervals (of fixed time) processed so far

c_thresh_baseline: u8

The baseline (starting) contrast threshold for all pixels

c_thresh_max: u8

The maximum contrast threshold for all pixels

c_increase_velocity: u8

The velocity at which to increase the contrast threshold for all pixels (increment c by 1 for every X input intervals, if it’s stable)

delta_t_max: u32

The maximum time difference between events of the same pixel, in ticks

ref_time: u32

The reference time in ticks

crf_quality: u8

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

• The baseline (starting) c-threshold for all pixels
• The maximum c-threshold for all pixels
• The Dt_max multiplier
• The c-threshold increase velocity (how often to increase C if the intensity is stable)
• The radius for which to reset the c-threshold for neighboring pixels (if feature detection is enabled)

feature_detection: bool

Whether or not to detect features

feature_c_radius: u16

The radius for which to reset the c-threshold for neighboring pixels (if feature detection is enabled)
