Fixed issues:

  • keepalive command response is now correct. The problem with disconnects solved
  • Timezone is obtained on connection start via GETCTRLUTC directive. Device's timezone is used to shift timestamp registered in messages.
  • new directive command added that will form JSON automatically (compared to custom command)

Parsing of Extended data format №1 has been added to the protocol. It works only with enabling this config, cause the device doesn't report any data bout current ext. format. The option is in the device configuration tab.

      streamax protocol updated: message registered on every device connection replaced with the device_info setting

        streamax protocol update scheduled for October 13, 2023 - parameter event.enum will be removed. It displays payload type of the message and in most cases it's always 0 (signal message).

          Added VIDEO download and snapshot (photo) taking.
          You can request videos and photos on the MEDIA tab, which becomes available when you enable the experimental functionality in your account settings.
          Or using the "request_video" and "take_photo" device commands - they will be sent and repeated up to 3 times until device finish media file upload. Those commands results will contain all information about uploaded media file.

          When you click on the video download button, an additional window will appear in which you have to select:

          1. Camera channel as a video source
          2. Indicate the time that will serve as the beginning of the video
          3. Duration of the video

          All necessary information for the video file is recorded in logs and messages:

                    streamax protocol update: added new standard video commands playback_video and video_timeline.

                    The playback_video command performs almost the same function as request_video, except its result is an HLS live stream URL, allowing you to view the historical video almost immediately, without waiting for the full file upload.

                    The video_timeline command enables you to retrieve time intervals with video recordings stored on the disk, which are available for download/playback.
