setRtmpShouldSendPings method
启用 RTMP 周期 ping,用于测量往返时延(RootEncoder 2.7.0+,仅 Android)。
须在 startVideoStreaming 之前调用;getStreamStatistics 中的 StreamStatistics.rttMicros 依赖此项。
Implementation
Future<void> setRtmpShouldSendPings(bool enabled) async {
if (!value.isInitialized! || _isDisposed) {
throw CameraException(
'Uninitialized CameraController.',
'setRtmpShouldSendPings was called on uninitialized CameraController',
);
}
if (!Platform.isAndroid) {
throw CameraException(
'Unsupported platforms.',
'setRtmpShouldSendPings is only supported on Android.',
);
}
try {
await _channel.invokeMethod<void>(
'setRtmpShouldSendPings',
<String, dynamic>{'enabled': enabled},
);
} on PlatformException catch (e) {
throw CameraException(e.code, e.message);
}
}
