DVR Settings

The <DVRSettings> block enables nDVR (network Digital Video Recording) functionality, providing a short live-stream rewind mechanism based on an in-memory cache of the stream data. This allows viewers to pause and rewind a live stream within the cached time window.

Available in: mono, origin, edge

Sample Configuration

DVRSettings block

xml

<DVRSettings enabled="true">
    <CacheSize>100</CacheSize>
</DVRSettings>

Parameters

Parameter	Description	Default
`DVRSettings:enabled`	Enables or disables DVR functionality for this application.	`false`
`<CacheSize>`	Amount of memory (in MB) allocated for storing the cached video stream. The actual rewind duration depends on the stream's resolution and bitrate.	`100`

Note

DVR cache is stored in memory. For high-bitrate streams, 100 MB may only provide a few minutes of rewind. Plan your <CacheSize> accordingly based on the expected stream bitrate.

Environment Variables

All parameters support environment variables using the ${EV:VARIABLE_NAME} syntax. Fields locked by environment variables cannot be modified via the REST API.
