Description

While implementing DRM, I needed to call the HTMLMediaElement: encrypted event; however, upon callback, the event is missing the MediaEncryptedEvent.initDataTypeand MediaEncryptedEvent.initData event properties, which I need in order to finish the implementation. Can this be looked into? 🙏

P.S. I can see that there is work being done on native DRM, that is awesome! However, for now I can do it myself, but not without the proper callback. Thanks!

Reduced test case

Steps to reproduce

1. <mux-video>.addEventListener('encrypted', async (event) => await handleEncrypted(event, assetId));

const handleEncrypted = async (event: MediaEncryptedEvent, assetId: string) => {
  try {
    console.log('Encrypted event:', event);
    const initDataType = event.initDataType;
    if (initDataType !== 'skd') {
      console.error(`Received unexpected initialization data type "${initDataType}"`);
      return;
    }

...

3. Result in Safari console:
   

Current Behavior

initDataType and initData are not included in video->encrypted callback

Expected Behavior

initDataType and initData should be included in the event

Ok, I managed to get around this, and in any case this is super specific so I think we can wait for #905 without this being resolved 🙏 closing
