## Video metadata {#video-metadata}

We can introduce metadata calculation based on came name and time.

For example we have 2 camera:
- id2020
- id2021

`streamer` save video in path {root_path}/{camera-id}/{time_path}

#### time path {#time-path}

If we have same range for all cameras we can introduce path managment. For example:
- 20-06-2020/13-00/video.mp4
- 20-06-2020/13-05/video.mp4
- 20-06-2020/13-10/video.mp4

When camera moved to another `streamer` it cut video to that format (for example if camera moved on 3rd minute we will have two parts on two stores)

### `streamer` dies

Every time when `streamer` start consuming video it tells about that to DB/queue - "streamer #4 start consuming video from camera id2020 at 15-10-2020 15:04"
