# Player configuration
After you [embed](/docs/wowza-flowplayer/player/embed/embed-with-standalone/) Wowza Flowplayer, it can be configured through the manual Javascript player setup below. Configuration is added to the `flowplayer()` call in the second argument:
```js
flowplayer('#player_container', {
src: "my_video.mp4",
token: "[your-player-token]",
title: "my video",
autoplay: true
})
```
## Configuration options
Wowza Flowplayer uses the configurations mentioned in the Core Player Configuration table below by default. You can override them by manually setting options.
All other configuration options (Autoplay, User Interface, and Plugins) need to be set manually by adding them to the embed code.

### Autoplay configuration

Info
Use `autoplay` with caution and keep in mind that most browsers do not allow autoplay with sound in many situations; we expect policies to become even more restrictive in the future. Autoplaying videos can be an irritant to users (especially when muted) and might waste bandwidth and battery energy. Check the current browser policies here:
* [Chrome](https://developers.google.com/web/updates/2017/09/autoplay-policy-changes)
* [Firefox](https://developer.mozilla.org/en-US/docs/Web/Media/Autoplay_guide)
* [iOS Safari](https://webkit.org/blog/6784/new-video-policies-for-ios/)
* [iOS MacOS](https://webkit.org/blog/7734/auto-play-policy-changes-for-macos/)
### User interface configuration
The following options are available in the `ui` configuration object.
To combine several options, add the values and configure the sum.
Example:
`NO_HEADER | NO_TITLE | LOGO_RIGHT` will have the numeric values
`4096 | 256 | 8` and the resulting config value for
`"ui":` will be `4360`.

Note the UI flags are configured without quotes and are case-sensitive.

### Plugins configuration
Wowza Flowplayer can be extended through the use of various plugins. To learn more about these plugins and how to configure them for usage with the player, see [Plugin configurations](/docs/wowza-flowplayer/plugins/about-plugins/#plugin-configuration).
## Video source
The source ( root level `"src": option`) can be configured either as a/an:
embed
Info
If you configure a source array with several source types like `m3u8`, `mp4` and `webm`, they will be evaluated in the order they're written and the first source the browser supports will be played. This means that you should always list m3u8 first if you want to offer quality selection for example.
