◆ ~IMediaRecorder()
◆ setMediaRecorderObserver()
Registers the IMediaRecorderObserver observer.
- Since
- v4.0.0
This method sets the callback for audio and video recording, so the app can be notified of recording status and information during the recording process. Before calling this method, make sure that:
- The
IRtcEngine object has been created and initialized.
- The media recorder object has been created using
createMediaRecorder.
- Parameters
-
| callback | Callback for audio and video stream recording. See IMediaRecorderObserver. |
- Returns
- 0: Success.
- < 0: Failure. See
Error Codes for details and resolution suggestions.
◆ startRecording()
Starts audio and video stream recording.
- Since
- v4.0.0
This method starts recording audio and video streams. The Agora SDK supports recording both local and remote users' audio and video streams simultaneously. Before starting the recording, make sure that:
- You have created the media recorder object using
createMediaRecorder.
- You have registered a recorder observer using
setMediaRecorderObserver to listen for recording callbacks.
- You have joined a channel. This method supports recording the following data:
- Audio captured from the microphone in AAC encoding format.
- Video captured from the camera in H.264 or H.265 encoding format. After recording starts, if the video resolution changes during recording, the SDK stops the recording. If the audio sample rate or number of channels changes, the SDK continues recording and generates a single MP4 file. A recording file is only successfully generated when a recordable audio or video stream is detected. If there is no recordable stream, or if the stream is interrupted for more than 5 seconds during recording, the SDK stops the recording and triggers the
onRecorderStateChanged (RECORDER_STATE_ERROR, RECORDER_REASON_NO_STREAM) callback.
- Note
- If you want to record local audio and video streams, make sure the local user role is set to broadcaster before starting recording.
- If you want to record remote audio and video streams, make sure you have subscribed to the remote user's streams before starting recording.
- Parameters
-
| config | Audio and video stream recording configuration. See MediaRecorderConfiguration. |
- Returns
- 0: Success.
- < 0: Failure. See
Error Codes for details and resolution suggestions.
- -2: Invalid parameter. Please ensure that:
- The specified recording file path is correct and writable.
- The specified recording file format is correct.
- The maximum recording duration is set correctly.
- -4:
IRtcEngine is in a state that does not support this operation. This may be because a recording is already in progress or has stopped due to an error.
- -7:
IRtcEngine is not initialized when this method is called. Please make sure the IMediaRecorder object has been created before calling this method.
