getPlayAddressWithPassword method

Future<Map<String, dynamic>> getPlayAddressWithPassword(String deviceSerial, String password, { int channelNo = 1, int protocol = 1, int quality = 1, bool debug = false, })

Get live stream with automatic encryption handling.

This method tries to get the stream without password first, and if encryption error occurs, it will retry with the provided password.

deviceSerial: The device serial number password: Video encryption password channelNo: Channel number (default: 1) protocol: Protocol type (0: RTMP, 1: HLS, 2: FLV, 3: WebRTC) quality: Video quality (0: Smooth, 1: HD, 2: Ultra HD) debug: Enable debug logging
