getStreamUri2 method

Future<String> getStreamUri2(
  1. String profileToken, {
  2. String protocol = 'RTSP',
})

This operation requests a Uri that can be used to initiate a live media1 stream using RTSP as the control protocol. The returned URI shall remain valid indefinitely even if the profile is changed.

The correct syntax for the StreamSetup element for these media1 stream setups defined in 5.1.1 of the streaming specification are as follows:

  1. RTP unicast over UDP: StreamType = "RTP-Unicast", TransportProtocol = "UDP"
  2. RTP over RTSP over HTTP over TCP: StreamType = "RTP-Unicast", TransportProtocol = "HTTP"
  3. RTP over RTSP over TCP: StreamType = "RTP-Unicast", TransportProtocol = "RTSP"

If a multicast stream is requested at least one of videoEncoderConfiguration, audioEncoderConfiguration and metadataConfiguration shall have a valid multicast setting.

For full compatibility with other ONVIF services a device should not generate Uris longer than 128 octets.

Implementation

Future<String> getStreamUri2(
  String profileToken, {
  String protocol = 'RTSP',
}) async =>
    _mediaSupportLevel == MediaSupportLevel.one
        ? throw NotSupportedException()
        : media2.getStreamUri(profileToken);
