# Playlist

### Source

It is the smallest unit for playing video from OvenPlayer. It is generally a single content.

{% code title="example" %}

```
let player = OvenPlayer.create("player", {
        type : "mp4", 
        file :  "https://path.to/your_video", 
        framerate : 30,
        label : "360P"
    });
```

{% endcode %}

### Sources

If you have multiple protocols or multiple resolutions for a single content, you can register them at once using `sources`. 

OvenPlayer will play a video in the order of the protocol or resolution you entered in `sources`, and will automatically play the next source if playback fails.

{% code title="" %}

```
let player = OvenPlayer.create("player", {sources : [
    {
        type : "mp4", 
        file :  "https://path.to/your_video", 
        framerate : 30,
        label : "360P"
    },
    {
        type : "mpd", 
        file :  "https://path.to/your_video.mpd", 
        framerate : 30,
        label: "360P DASH"
    },
    {
        type : "hls", 
        file :  "https://path.to/your_video.m3u8", 
        framerate : 30,
        label: "360P HLS"
    },
    {
        type : "rtmp", 
        file :  "rtmp://path.to/your_video", 
        framerate : 30,
        label: "360P RTMP"
    }
] });
```

{% endcode %}

### Playlist 

`playlist` has multiple `sources` mentioned above. You can explore between playlists, and it automatically plays the next content. Also, you can assign ads and captions for each `playlist`.
