Downsmash is a parser for Super Smash Bros. Melee. It extracts data from raw video feed.

This should work on Windows, since opencv-python packages its own OpenCV. I cannot guarantee this, though, and I cannot help Windows users with configuration.

$ git clone https://github.com/downsmash/downsmash
$ pip install -r requirements.txt

You will also probably want to use a video downloader such as yt-dlp.

Download a video containing one Melee set to melee_vod.mp4, then:

from downsmash.watcher import watch
watch('melee_vod.mp4')

watch will send back a JSON object. Let's use this set from Low Tide City.

{
  "segments": [
    [ 16.7109375, 222.734375 ],
    [ 249.171875, 472.65625 ],
    [ 504.171875, 607.65625 ]
  ],
  "threshold": 0.3982072589975415,
  "view": {
    "ports": [
      {
        "height": 96,
        "left": 102,
        "top": 255,
        "width": 119
      },
      null,
      null,
      {
        "height": 96,
        "left": 403,
        "top": 255,
        "width": 130
      }
    ],
    "scale": 0.7853535353535352,
    "screen": {
      "height": 322.8675645342311,
      "left": 102.61111111111106,
      "top": 32.84343434343428,
      "width": 430.4900860456415
    }
  }
}

In this case, segments contains the timestamps of the start and end of the three games in the set, and view contains the scale and location of the game feed, as well as the ports in use and their locations.
