camera recording

[Flynn2018]

Can the plugin provide methods to control the camera for recording, such as starting and ending recording? And also add the feature to get stream address of playback video?

Hi @Flynn2018 ,

The package does not yet support recording/playback as part of the high-level API, however you could access this functionality with low-level calls:

As shown here in the README

So you could so something like: (you will have to refer to the appropriate Onvif spec doc for tags and namespaces)

// sample low level request
//
// build a xml fragment for the specific Onvif operation
final tt = 'http://www.onvif.org/ver10/schema';
final trp = 'http://www.onvif.org/ver10/replay/wsdl';

Transport.builder.element('GetReplayUri', nest: () {
  Transport.builder.namespace(trp);

  Transport.builder.element('StreamSetup', nest: () {
    Transport.builder.element('Stream', nest: () {
      Transport.builder.namespace(tt);
      Transport.builder.text('RTP-Unicast',);
    });

    Transport.builder.element('Transport', nest: () {
      Transport.builder.namespace(tt);
      Transport.builder.element('Protocol', nest: () {
        Transport.builder.text('RTSP');
      });
    });
  });

  Transport.builder.element('RecordingToken', nest: () {
    Transport.builder.text(recordingToken);
  });
});

final requestFragment = Transport.builder.buildFragment();

// build the soap request envelope and send the request
final envelope = await onvif.transport.sendRequest(
    [device reply uri determined through deviceManagement.getServices],
    transport.securedEnvelope(requestFragment),
);

print(envelope.body.response);

In terms of adding support for this functionality, it would likely be a few months before this is added to the package. Though donations do help items move up on the priority list :-)

Also, if you are able to get things working with low-level calls, please pass along some sample code as it would make creating the high-level supporting methods much easier.

@Flynn2018 ,

Initial support for recording has been added to v2.1.1-dev.1, but I don't really have a device to fully test the new code. Please let me know if any of it works for you.
