subplay

Motivation

I needed a simple parser/player of .srt files.

Installing with NPM

npm install -S subplay

Installing with Bower

bower install -S subplay

Usage

var subplay = require('subplay');

// get hold of an srt as a string
var srt = fs.readFileSync('./mysubs.srt', 'utf-8');

// the second argument is a renderer funtion which
// will be called for every update that is to be
// made to the subtitles.
var update = subplay(srt, function(text) {
    // text is either an (html formatted) text
    // or '' when clearing
    // example of updating a div using jQuery
    $('#mysubholder').html(text);
});

// pass the current time to the update function which
// takes current time in seconds with fractions.
$('video').on('timeupdate', function(ev) {
    // this is 20.5 sec for 20 seconds and a bit into the video
    update(ev.target.currentTime);
});

API

update = subplay(srt, renderer, opts) where srt is the srt to be played as a string and renderer is a function that will be called every time there is an update to be made. returns an update function which is used to control where the srt is playing.

opts.millis whether the time passed to the update-function are in millis. otherwise assumed to be seconds. defaults to false

update(time) start/update the time position of the srt player. the time passed is in millis or seconds depending on opts.millis. a negative value stops the player. this method can be called as many times as needed. it will reset/resync the player to whatever position is passed as argument.
