Method Detail

onRecordAudioFrame

int onRecordAudioFrame(AgoraLocalUser agoraLocalUser,
                       java.lang.String channelId,
                       AudioFrame frame)

Note: To improve data transmission efficiency, the buffer of the frame object is a DirectByteBuffer. Be sure to extract the byte array value in the callback synchronously and then transfer it to the asynchronous thread for processing. You can refer to Utils.getBytes(ByteBuffer).

Parameters:

agoraLocalUser - the local user

channelId - the channel id

frame - the audio frame

Returns:

0/1, the return value currently has no practical significance

onPlaybackAudioFrame

int onPlaybackAudioFrame(AgoraLocalUser agoraLocalUser,
                         java.lang.String channelId,
                         AudioFrame frame)

Note: To improve data transmission efficiency, the buffer of the frame object is a DirectByteBuffer. Be sure to extract the byte array value in the callback synchronously and then transfer it to the asynchronous thread for processing. You can refer to Utils.getBytes(ByteBuffer).

Parameters:

agoraLocalUser - the local user

channelId - the channel id

frame - the audio frame

Returns:

0/1, the return value currently has no practical significance

onMixedAudioFrame

int onMixedAudioFrame(AgoraLocalUser agoraLocalUser,
                      java.lang.String channelId,
                      AudioFrame frame)

Note: To improve data transmission efficiency, the buffer of the frame object is a DirectByteBuffer. Be sure to extract the byte array value in the callback synchronously and then transfer it to the asynchronous thread for processing. You can refer to Utils.getBytes(ByteBuffer).

Parameters:

agoraLocalUser - the local user

channelId - the channel id

frame - the audio frame

Returns:

0/1, the return value currently has no practical significance

onEarMonitoringAudioFrame

int onEarMonitoringAudioFrame(AgoraLocalUser agoraLocalUser,
                              AudioFrame frame)

Note: To improve data transmission efficiency, the buffer of the frame object is a DirectByteBuffer. Be sure to extract the byte array value in the callback synchronously and then transfer it to the asynchronous thread for processing. You can refer to Utils.getBytes(ByteBuffer).

Parameters:

agoraLocalUser - the local user

frame - the audio frame

Returns:

0/1, the return value currently has no practical significance

onPlaybackAudioFrameBeforeMixing

int onPlaybackAudioFrameBeforeMixing(AgoraLocalUser agoraLocalUser,
                                     java.lang.String channelId,
                                     java.lang.String userId,
                                     AudioFrame frame,
                                     VadProcessResult vadResult)

Note: To improve data transmission efficiency, the buffer of the frame object is a DirectByteBuffer. Be sure to extract the byte array value in the callback synchronously and then transfer it to the asynchronous thread for processing. You can refer to Utils.getBytes(ByteBuffer).
