startNetworkDetection abstract method

Future<int?> startNetworkDetection({ required bool isTestUplink, required int expectedUplinkBitrate, required bool isTestDownlink, required int expectedDownlinkBitrate, })

Starts pre-call network detection.

isTestUplink: Whether to detect uplink bandwidth.

expectedUplinkBitrate: Expected uplink bandwidth in kbps within a range of {0, [100-10000]}. 0 indicates that the maximum code rate is specified by the SDK.

isTestDownlink: Whether to detect downlink bandwidth.

expectedDownlinkBitrate: Expected downlink bandwidth in kbps within a range of {0, [100-10000]}. 0 indicates that the maximum code rate is specified by the SDK.

Return value:

• 0: Success.
• <0: Failure. See ReturnStatus for the reason.

Notes:

• After a successful call to this API, the RTCVideoEventHandler.onNetworkDetectionResult callback will be received once in 3s and every 2s thereafter to notify the detection result.
• If detection is stopped, the detection will be notified once by RTCVideoEventHandler.onNetworkDetectionStopped.
