false: The video packet is discarded.

onStreamMessage

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

public void onStreamMessage(int uid, int streamId, byte[] data) {}

Attention: If you need a more comprehensive solution for low-latency, high-concurrency, and scalable real-time messaging and status synchronization, it is recommended to use Signaling.

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

Parameters

uid: The ID of the remote user sending the message.
streamId: The stream ID of the received message.
data: The data received.

onStreamMessageError

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

public void onStreamMessageError(int uid, int streamId, int error, int missed, int cached) {}

Attention: If you need a more comprehensive solution for low-latency, high-concurrency, and scalable real-time messaging and status synchronization, it is recommended to use Signaling.

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

uid: The ID of the remote user sending the message.
streamId: The stream ID of the received message.
error: Error code.
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.

public void onUplinkNetworkInfoUpdated(UplinkNetworkInfo 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.
