Available in: mono, origin, transcode, edge

Sample Configuration

GeneralSettings block

xml

<GeneralSettings>
    <Description>Default application</Description>
    <BroadcastLimit>300</BroadcastLimit>
    <StatInterval>2</StatInterval>
    <AutoThumbnails enabled="true">
        <Interval>2</Interval>
        <ThumbWidth>1280</ThumbWidth>
        <ThumbHeight>720</ThumbHeight>
    </AutoThumbnails>
</GeneralSettings>

Parameters

Parameter	Description	Default
`<Description>`	A custom description of the application explaining its purpose and functionality.	—
`<BroadcastLimit>`	Maximum number of concurrent broadcasts allowed within this application. Leave empty for no limit.	—
`<StatInterval>`	How frequently statistics are processed for this application, expressed in seconds.	`2`

AutoThumbnails

The <AutoThumbnails> sub-block enables automatic thumbnail generation from active streams. Thumbnails are generated periodically and can be used for stream previews in the Control Panel or via the REST API.

AutoThumbnails example

xml

<AutoThumbnails enabled="true">
    <Interval>2</Interval>
    <ThumbWidth>1280</ThumbWidth>
    <ThumbHeight>720</ThumbHeight>
</AutoThumbnails>

Parameter	Description	Default
`AutoThumbnails:enabled`	If set to `true`, the server will automatically generate thumbnail images from active streams.	`false`
`<Interval>`	How often thumbnails are generated, expressed in seconds.	`2`
`<ThumbWidth>`	Width of the generated thumbnail in pixels. Leave empty for automatic scaling based on the source.	—
`<ThumbHeight>`	Height of the generated thumbnail in pixels. Leave empty for automatic scaling based on the source.	—

Note

Thumbnail generation requires FFMPEG to be installed on the system. The <ThumbGenerateTaskLimit> parameter in the Transcoder Configuration controls the maximum number of concurrent thumbnail generation tasks.

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.
