Function aligner::align
[−]
[src]
pub fn align(list: Vec<TimeSpan>,
reference: Vec<TimeSpan>,
split_penalty_normalized: f64,
progress_handler: Option<Box<ProgressHandler>>)
-> Vec<TimeDelta>
Matches an incorrect
subtitle list to a reference
subtitle list.
Returns the delta for every time span in list.
The split_penalty_normalized
is a value between
0 and 1. Providing 0 will make the algorithm indifferent of splitting lines (resulting in MANY
different deltas), so this is not recommended. Providing 1 will assure that no split will occur,
so only one/the best offset is applied to ALL lines. The most common useful values are in the
0.2 to 0.01 range.
Especially for larger subtitles(e.g. 1 hour in millisecond resolution and 1000 subtitle lines) this
process might take some seconds. To provide user feedback one can pass a ProgressHandler
to
this function.
