L.distortableVideo(videoUrl, corners, options)

To instantiate a L.DistortableVideo, specify the video URL or videoElement, four corner points, and any L.VideoOverlay options in the L.distortableVideo factory method, for example:

var corners= {
            topLeft: L.latLng([30,-129]),
            topRight: L.latLng([32,-100]),
            bottomRight: L.latLng([13,-97]),
            bottomLeft: L.latLng([13,-130])
};

let layer = L.distortableVideoOverlay("https://www.mapbox.com/bites/00188/patricia_nasa.mp4", corners, {
  opacity: 0.8
}).addTo(map);

topLeft, topRight, bottomLeft and bottomRight are instances of L.LatLng, corresponding to the locations of the corners of the video. corners can be also L.LatlngBounds in factory method.

Corners can be also array of points. The order of the points is topLeft, topRight, bottomRight and bottomLeft.

var topLeft = L.latLng([30, -129]);
var topRight = L.latLng([32, -100]);
var bottomRight = L.latLng([13, -97]);
var bottomLeft = L.latLng([13, -130]);
var corners = [topLeft, topRight, bottomRight, bottomLeft];

let layer = L.distortableVideoOverlay("https://www.mapbox.com/bites/00188/patricia_nasa.mp4", corners, {
  opacity: 0.8
}).addTo(map);

setCorners(corners)

This function enables to relocate the video on the map, for example:

var corners= {
            topLeft: L.latLng([30,-129]),
            topRight: L.latLng([32,-100]),
            bottomRight: L.latLng([13,-97]),
            bottomLeft: L.latLng([13,-130])
};

overlay.setCorners(corners);
