# video.js HLS Plugin
A video.js plugin that plays HLS video on platforms that don't support it but have Flash.

- Subtitles

### Plugin Options
You may pass in an options object to the hls plugin upon initialization. This
object may contain one of the following properties:
#### withCredentials
Type: `boolean`
When the `withCredentials` property is set to `true`, all XHR requests for
manifests and segments would have `withCredentials` set to `true` as well. This
enables storing and passing cookies from the server that the manifests and
segments live on. This has some implications on CORS because when set, the
`Access-Control-Allow-Origin` header cannot be set to `*`, also, the response
headers require the addition of `Access-Control-Allow-Credentials` header which
is set to `true`.
See html5rocks's [article](http://www.html5rocks.com/en/tutorials/cors/)
for more info.
### Runtime Properties
