paella-webgl-plugins
A set of canvas plugins to show videos using a WebGL canvas.
## Usage
Step 1: Import the plugin context and add it to the Paella Player initialization parameters:
Usin plugin context API:
...
import getWebGLPluginsContext from 'paella-webgl-plugins';
let paella = new Paella('player-container', {
customPluginContext: [
getWebGLPluginsContext()
]
});
...
Using explicit plugin import API (paella-basic-plugins >= 1.41):
...
import {
webglPlugins, // All plugins
} from 'paella-webgl-plugins';
let paella = new Paella('player-container', {
plugins: [
...webglPlugins
]
});
...
From version 1.42.1, you can also use the generic plugin array name to import all the plugins:
import { allPlugins as webglPlugins } from 'paella-webgl-plugins'
...
All the plugin libraries exports the allPlugins
array. This is done in order to have a method to import all plugins using always the same name for all libraries.
Step 2: Configure the plugins you want to use in the paella player configuration.

Video 360 Canvas
It is a canvas plugin that allows you to display 360-degree videos recorded in equirectangular format. Mouse or touch actions on the canvas are used to zoom and scroll the video, therefore with this canvas the play/pause by clicking on the video canvas is disabled.
This video canvas works with those streams that have video360
as canvas identifier in the video manifest.
