How to use this library to detect SupportedCDMs

[vanminhquangtri]

I have used Videojs already and want to use videojs-contrib-eme to detect the support DRM key before apply the DRM. But I don't actually understand how to use detectSupportedCDMs(). I see it has player.eme.detectSupportedCDMs() but don't understand what is player here?

This is my main code:
import 'videojs-contrib-eme'

window.player = window.videojs(
        videoElement,
        myConfigObject,
        () => {
          window.player.eme()
        }
)

But it keep show error: window.player.eme is not a function

The function is replaced with an object when the plugin has initialised. this.eme() initialises the plugin, so player.eme is now an object. It should only be called once.

Hello @lapalb , I still can't get what you mean. A bit confused. If posible can you please give me a code sample. That's would be much easier to understand. Thank you.

@lapalb it seem the plugin is added success. But the player.eme.detectSupportedCDMs() not work.
it show error player.eme.detectSupportedCDMs is not a function
Can you please advice how to fix this?
Do I need to pass any param to player.eme() method?
This is my code:

import('video.js').then(function ({ default: videojs }) {
        import('videojs-contrib-eme').then(function () {
          const videoNode = document.getElementById('videoPlayer')
          if (!videoNode) return
          videojs.registerPlugin('eme', videojsContribEme)
          const player = videojs(videoNode, {}, function () {
            try {
              player.eme()
              player.eme.detectSupportedCDMs().then((supportedCDMs) => {
                console.log(supportedCDMs)
              })
            } catch (e) {
              console.log(e)
            }
          })
        })
      })

@vanminhquangtri I am also facing the same issue, maybe they forgot to expose the function as I cannot see detectSupportedCDMs inside the eme object.
