on_disconnect
The `on_disconnect` directive allows specification of actions to be taken when a client disconnects from the RTMP stream.
Description
The on_disconnect directive is used within the context of an application block in the NGINX RTMP module configuration. It enables server administrators to define custom actions that should be executed when a client disconnects from a stream. This can be particularly useful for scenarios that require cleanup operations, notifications, or logging of disconnect events.
When implementing on_disconnect, you can specify a script or function that the server will call at the time of disconnection. This allows for customized behaviors such as updating a database, triggering a notification system, or executing a series of commands tailored to your streaming application. The behavior is generally defined by providing a single argument as a string, which represents the command to be executed.
As with many directives in NGINX, it is crucial to ensure that the defined actions do not introduce excessive overhead, as these will be executed in the context of the RTMP session handling. Depending on how the command is defined, missteps in the configuration could lead to performance issues or unhandled exceptions, impacting the overall responsiveness of the streaming service.
Config Example
application live {
on_disconnect notify_disconnect;
}
# Where 'notify_disconnect' is a defined command or function to handle disconnect events.Ensure the command specified for on_disconnect is correctly defined prior to its use.
Long-running scripts or commands may negatively impact the streaming performance if not handled asynchronously.
Test the defined disconnect behaviors thoroughly to avoid unintended consequences or failures in live environments.
