I think SEI is part of the encrypted data, so if you cannot decrypt the Video Frame data, Browser cannot parse the SEI information correctly
Discussed in 2022-02-21 meeting. I suggest adding a short description to the explainer that it may not be possible to expose SEI events with video that is protected using EME.
This question relates to potential implementation considerations. When the media is encrypted for use with EME (e.g., ISO Common Encryption), are SEI events part of the encrypted data? If so, are browser implementations able to access the SEI event and surface them to the web application?
