# Resume Playing

With the Resume Playing feature, users are able to automatically resume content where it left off and which has been played on the specific device. 

**The feature has two modes:**

- **On device (Local)**: all viewing data is saved directly on the device. Videos will resume playback from where the user left off.
Additionally, on **mobile** devices, unfinished items can be promoted on screen. See more info [here](https://docs.applicaster.com/using-zapp/player/resume-playing#promote-unfinished-items-on-a-screen).
This is **not possible** on TV platforms and the Web. 

- **Cross-Device (Remote)**: all watching data is stored on a remote server and can be persistent on all the specific user's devices. 

### Prerequisites
Remote implementation will require to implement APIs on the server and will require to hook into a login mechanism to be able to identify the same user on different devices.

For implementing APIs please read the following:

[Implementing "Video Stopped" cloud event](https://docs.applicaster.com/integrations/cloud-events/#video-stopped-comapplicastervideostoppedv1)

[Implementing "Continue Watching" feeds](https://docs.applicaster.com/integrations/continue-watching-feed)

### Plugin Configuration

Modify the feature setting according to your needs:

**Minimum content duration** means that below the minimum duration the content won't be tracked.

**Completion threshold** is the default duration from the end of the content to consider it viewed and clear it from tracked items.

**Update frequency** The number of seconds between two updates of the resume time.

**Maximum number of items tracked** is the number of tracked and saved items. 

**Image asset key name** defines the key that is used for the image assigned to the continue watching data source (`image_base`). Relevant only for Mobile or Server Sync. 

### Remote Mode Implementation

**Enable server sync:** Toggle is to enable/disable remote syncing.

**Watched segment URL:** The URL of the "Video Stopped" cloud event.

**User identifier storage key:** The plugin will use this key to identify the user. To determine what is the storage key name, please consult with your account manager or your custom login plugin developers.

**Synced feed:** The Feed JSON holds the list of videos the user started and didn't finish. To develop your own custom synced feed please refer to the Implementing "Continue Watching" feeds doc.

### Promote Unfinished Items on a Screen

#### Local Mode (Mobile only)

You can promote a component with the content that can be resumed. 
In order to do so, create a new pipes feed with the URL.

```json
 pipesv2://continue-watching 
 ```

Then, create a component with cell style and use the feed you’ve created. The component will display once the users will have a content that they started to watch.

#### Cross-Device (Remote)

*Mobile and TV*: Create a normal JSON feed that holds the list of unfinished items. [Read here](https://docs.applicaster.com/integrations/continue-watching-feed) on how to implement it. 

*Web*: Create a new pipes feed with the URL: 

```json
 pipesv2://continue-watching 
 ```

Then, create a component with cell style and use the feed you’ve created. The component will display once the users will have a content that they started to watch.
