Add a georeferenced video layer

Usage

add_video(
  map,
  urls,
  coordinates,
  name = "Video",
  style = list(),
  visible = TRUE,
  opacity = 1,
  ...
)

Arguments

map: A GeoLibre widget.
urls: One video URL, or several as format fallbacks such as MP4 then WebM. URLs must be https://, since the browser's media policy blocks plain HTTP.
coordinates: Four c(longitude, latitude) corners in top-left, top-right, bottom-right, bottom-left order, given as a list of pairs or a four-row matrix.
name: Layer name.
style: Named list of GeoLibre style overrides such as fillColor, strokeColor, and strokeWidth.
visible: Whether the layer is initially visible.
opacity: Layer opacity from zero to one.
...: Additional style overrides given as named arguments, merged into style. add_geojson(map, data, fillColor = "red") and add_geojson(map, data, style = list(fillColor = "red")) are equivalent.

Value

The modified widget.

map <- geolibre() |>

    )
