## Member Function Documentation

## ◆ onRtmpStreamingStateChanged()

virtual void agora::rtc::IRtmpStreamingObserver::onRtmpStreamingStateChanged | ( | const char * | url,
|  | RTMP_STREAM_PUBLISH_STATE | state,
|  | RTMP_STREAM_PUBLISH_REASON | reason )
| inline virtual

Occurs when the state of the RTMP streaming changes.

The SDK triggers this callback to report the result of the local user calling `addPublishStreamUrl` or `removePublishStreamUrl`.

This callback also reports the streaming URL and its current streaming state. When exceptions occur, you can troubleshoot issues by referring to the detailed error description in the `errCode` parameter.

Parameters

  url | The RTMP URL address.
  state | The RTMP streaming state: RTMP_STREAM_PUBLISH_STATE.
  reason | The detailed error information for streaming: RTMP_STREAM_PUBLISH_REASON.

## ◆ onRtmpStreamingEvent()

virtual void agora::rtc::IRtmpStreamingObserver::onRtmpStreamingEvent | ( | const char * | url,
|  | RTMP_STREAMING_EVENT | eventCode )
| inline virtual

Reports events during the RTMP or RTMPS streaming.

Since
  v3.1.0

Parameters

  url | The RTMP or RTMPS streaming URL.
  eventCode | The event code. See RTMP_STREAMING_EVENT

## ◆ onTranscodingUpdated()

virtual void agora::rtc::IRtmpStreamingObserver::onTranscodingUpdated | ( |  | ) |
| inline virtual

Occurs when the publisher's transcoding settings are updated.

When the `LiveTranscoding` class in the `setLiveTransocding` method updates, the SDK triggers this callback to report the update information.

Note
  If you call the `setLiveTranscoding` method to set the `LiveTranscoding` class for the first time, the SDK does not trigger this callback.
