Installation

Usage

var sequences = [{start: 0, end: 5}, {start: 12, end: 13}, {start: 21, end: 31}];
var sequencer = new MediaSequence(new Audio('path/to/audio.ogg'), sequences);

sequencer.playAll();

API

new MediaSequence(el, sequences)

sequencer.add(sequences)

Adds new sequences to the actual stack.

sequencer.playAll()

Registers event listeners and starts the playback of all the sequences in a row.

sequencer.playFrom(start, end)

Starts the playback from the start time and stops automatically at the end time.

sequencer.getNext(referenceTime, options)

Returns the next sequence from a referenceTime numbered value.

var ms = new MediaSequencer(…, [{ start: 3, end: 5 }, { start: 12, end: 13 }]);

ms.getNext(0);
// { start: 3, end: 5 }

ms.getNext(3);
// { start: 12, end: 13 }

If the options.overlap value is set to true, the returned sequence is allowed to overlap:

var ms = new MediaSequencer(…, [{ start: 3, end: 5 }, {start: 3, end: 10 }, { start: 12, end: 13 }]);

ms.getNext(3);
// { start: 12, end: 13 }

ms.getNext(3, { overlap: true });
// {start: 3, end: 5 }
