IPacketObserver

onReceiveAudioPacket

Occurs when the local user receives an audio packet.

virtual bool onReceiveAudioPacket(Packet& packet) = 0;

Parameters

packet: The received audio packet, see Packet.

Returns

true: The audio packet is received successfully.
false: The audio packet is discarded.

onReceiveVideoPacket

Occurs when the local user receives a video packet.

virtual bool onReceiveVideoPacket(Packet& packet) = 0;

Parameters

packet: The received video packet, see Packet.

Returns

true: The video packet is received successfully.
false: The video packet is discarded.

onSendAudioPacket

Occurs when the local user sends an audio packet.

virtual bool onSendAudioPacket(Packet& packet) = 0;

Parameters

packet: The sent audio packet, see Packet.

Returns

true: The audio packet is sent successfully.
false: The audio packet is discarded.

onSendVideoPacket

Occurs when the local user sends a video packet.

virtual bool onSendVideoPacket(Packet& packet) = 0;

Parameters

packet: The sent video packet, see Packet.

Returns

true: The video packet is sent successfully.
false: The video packet is discarded.

onStreamMessage

Occurs when the local user receives the data stream from the remote user.

virtual void onStreamMessage(uid_t userId, int streamId, const char* data, size_t length, uint64_t sentTs) {
                    (void)userId;
                    (void)streamId;
                    (void)data;
                    (void)length;
                    (void)sentTs;
                  }

The SDK triggers this callback when the local user receives the stream message that the remote user sends by calling the sendStreamMessage method.

Parameters

userId: The ID of the remote user sending the message.
streamId: The stream ID of the received message.
data: The data received.
length: The data length (byte).
sentTs: The time when the data stream is sent.

onStreamMessageError

Occurs when the local user does not receive the data stream from the remote user.

virtual void onStreamMessageError(uid_t userId, int streamId, int code, int missed, int cached) {
                (void)userId;
                (void)streamId;
                (void)code;
                (void)missed;
                (void)cached;
              }

The SDK triggers this callback when the local user fails to receive the stream message that the remote user sends by calling the sendStreamMessage method.

Parameters

userId: The ID of the remote user sending the message.
streamId: The stream ID of the received message.
code: Error code. See .
missed: The number of lost messages.
cached: Number of incoming cached messages when the data stream is interrupted.

onUplinkNetworkInfoUpdated

Occurs when the uplink network information changes.

virtual void onUplinkNetworkInfoUpdated(const UplinkNetworkInfo& info) {
  (void)info;
}

The SDK triggers this callback when the uplink network information changes.

Attention: This callback only applies to scenarios where you push externally encoded video data in H.264 format to the SDK.

Parameters

info: The uplink network information. See UplinkNetworkInfo.
