on_publish_done
The `on_publish_done` directive allows you to specify a callback function triggered when a publish operation is completed in the NGINX RTMP module.
Description
The on_publish_done directive is part of the NGINX RTMP module, which facilitates real-time messaging protocol streaming. This directive is invoked after a publisher has finished broadcasting to the stream, making it useful for executing additional actions, such as logging or cleanup tasks after the streaming session ends. The directive takes one argument, which specifies the handler that will be called upon the completion of the publishing action. This offers flexibility in integrating custom logic into the streaming workflow, enhancing control over publishing events within the NGINX server context.
In practice, the usage of this directive typically involves linking an event handler, a script or a function that should be executed. This could include notifying other services or cleaning up resources related to the stream. The behavior of this directive is centralized around stream management, ensuring that any necessary post-processing can seamlessly integrate with the live streaming setup. This can significantly improve the workflow for applications utilizing live broadcasting, ensuring that actions following the publishing phase are executed reliably.
Config Example
rtmp {
server {
application live {
live on;
on_publish_done log_publish_done;
}
}
}Ensure the handler function specified is correctly implemented and can be accessed by NGINX.
If you forget to handle errors in your callback, it may disrupt the streaming workflow.
