Portal Commands

With MetaPortal you can add new commands and test them through the Developer Panel.

Added commands in MetaPortal can be called through special uuid-shortcuts. This greatly simplifies the development and updating of commands.

How to find the uuid shortcut?
  1. In the list of commands in the developer panel, click on the subtitle (example camera_zoom #2c2453)

  2. The copied label can be invoked via emitUuidAsync()


This method works if you have specified an API key


import React from 'react'

// ui
import Button from 'rsuite/Button'

// libs
import { usePlayer } from 'pixel-streaming'

export const CommandsUuid: React.FC<any> = () => {
const player = usePlayer()

const [disabled, setDisabled] = React.useState<boolean>(false)

const emitUuidAsync = (commandUuid: string) => async () => {
await player.cls.emitUuidAsync(commandUuid).then((res: any) => {
if (res) {
console.log('@@@callback', JSON.stringify(res, null, 4))

return (
