Description
Splitting off an idea from @ytakio in https://github.com/w3c/webcodecs/issues/94#issuecomment-828054996
I think WebCodecs needs a method to get Metadata (including feature check method, as informative in spec?)
Can you clarify what's meant by "including feature check method, as informative in spec"? Do you mean you'd like to query for what types of metadata could potentially be emitted?
It may be very useful even if WebCodecs just pass a start point of each Metadata byestream (like SPS,VUI,SEI...) to WebAPPs.
Can you elaborate on how it would be useful to apps?

Research direction
Start with the linked WebCodecs issue 94 comment and this issue's discussion about SPS, VUI, and SEI metadata during decoding. Review the existing WebCodecs API and specification entry points before proposing scope. Done requires agreement on which metadata applications can receive and whether a feature-check method is needed.
