I want to download/extract recorded archived video using start and end timestamp. Is there any API that provides me to download recorded video? I have gone through `http://localhost:7001/ec2/recordedTimePeriods` api. It lists period for custom start timestamp data. But. it's always return durationMs -1 until I restart recording. My problem is quite simple. I just want to get video using requested start time and end time stamp. Is there any direct api or solution for this?

  Hello Muhamed,

  Yes, there is. It's called video API. You can find the documentation in Web interface of the Server.

  http://localhost:7001/static/api.xml#group_Video_API

  For example, to get a RTSP stream starting from the specific timestamp try this
  rtsp://<server_ip>:<port>/12AB42FD5912?pos=1235631&resolution=240

  pos: By default, the server opens a camera at the live position. This parameter defines position in an archive (as a string containing time in milliseconds since epoch, or a local time formatted like "YYYY-MM-DDTHH:mm:ss.zzz" - the format is auto-detected). Position can be passed via standard RTSP attribute as well as via URL parameter

  The most suitable for your task would be HTTP streaming.

  http://<server_ip>:<port>/media/12AB42FD5912.webm

  It has pos and endPos parameters.

  Thanks for the response. Just for the confirmation, http://:/media/12AB42FD5912.webm this won't work when recording is disabled is it?

  http://:/media/12AB42FD5912.webm WILL work even when recording is disabled on a camera.

  However, if there are no recordings in the video archive for the time indicated by pos the API won't return a video, just because there is no video in the archive for that moment of time.

  One more thing.

  The recommended format is mp4. Like this

  http://:/media/12AB42FD5912.mp4

  In this case there is no transcoding and mp4 is more likely compatible.
