Cuemarker
Super simple helper for creating WebVTT cue times for HTML video elements.
Demo: http://tylergaw.github.io/webvtt-cuemarker/demo.html
What does it do?
- Adds a few keyboard controls to given html video element;
- Space bar for play/pause toggling
- Left/right arrow for seeking through the video
- Period "." for marking in/out points of each cue
- After each out point is set, the cue time is output in WebVTT format:
00:01:20.123 --> 00:05:10.212
Usage
Include cuemarker.js
in your super-sweet html www page!
<script src="/path/to/cuemarker.js"></script>
Initialize Cuemarker by passing it the video element you want it to watch
var video = document.getElementById('my-video');
cuemarker(video);
NOTE: The element needs to be a DOM element, not a jQuery object. If you're using
jQuery you can access the DOM element using get()
var video = $('#my-video').get(0);
While the video is playing, pressing the "."/">" key will set an in point. Pressing
the key again will set an out point and call the output
function. The cuetime
will be passed to output
. The
next "."/">" keypress will set an in point.
Options
You can modify the seekInterval and output by providing an options map as a second
parameter to cuemarker
cuemarker(video, {
seekInterval: 2.5,
output: function (cuetime) {}
});
Now copypasta those times to your vtt file.
What did I learn?
I learned that the native JavaScript map
method is supported really well as of
June 2013. I was under the impression that it was something that would not be
widely implemented until much later. I used it here https://github.com/tylergaw/webvtt-cuemarker/blob/master/cuemarker.js#L27
