` to your page ``. MKPlayer uses this element as the playback container:
```
```
### Create a player instance
In your JavaScript, get the container, build a configuration object, and pass both to `MKPlayer`:
```
const videoContainer = document.getElementById("video-container");
const playerConfig = {
key: "YOUR_PLAYER_LICENSE_KEY",
playback: {
muted: true,
autoplay: true
}
};
const player = new mkplayer.MKPlayer(videoContainer, playerConfig);
```
The player is now initialised and ready to load a source. See [Loading and playing content](https://docs.mediakind.com/mkio/reference/player-sdk/playback) for the next step.
## Player configuration options
The `MKPlayerConfig` object controls how the player behaves. All properties are optional except where noted.
| Property | Type | Description |
| --- | --- | --- |
| `key` | `string` | Your player license key. |
| `playback` | `MKPlaybackConfig` | Playback options such as `autoplay` and `muted`. |
| `ui` | `boolean` | Enables the built-in player UI. Requires `mkplayer-ui.css` to be loaded. Default: `false`. |
| `events` | `MKPlayerEventConfig` | Map of player events to handler callbacks. You can also register handlers dynamically using `player.on()`. |
| `analytics` | `MKAnalyticsConfig | false` | Analytics configuration. Set to `false` to disable analytics even if the analytics module is loaded. |
| `buffer` | `MKBufferConfig` | Buffer configuration. |
| `log` | `MKLogConfig` | Log level and output configuration. |
| `tweaks` | `MKTweaksConfig` | Advanced player tweaks. Use these only if you understand their effect on playback behaviour. |
## Additional requirements for Apple devices
Safari on Mac, iPhone, and iPad requires an extra step to support secure URLs and custom HTTP headers via `setHttpHeaders`.
1. Download `serviceWorker.js` from the MKPlayer SDK resources.
2. Place the file at the root of the domain where your web app is hosted, for example `https://yourdomain.com/serviceWorker.js`.
3. Explicitly enable `native_hls_parsing` in your player configuration:
```
const playerConfig = {
key: "YOUR_PLAYER_LICENSE_KEY",
tweaks: {
native_hls_parsing: true
}
};
```
The SDK enables `native_hls_parsing` by default if the property is not set, but setting it explicitly ensures consistent behaviour across environments.
