feature, it's no need to guard it by the preference anymore.

:alwu could you consider nominating this for a release note? (Process info)
We could include it in the nightly release notes.

FF129 MDN docs work can be tracked in https://github.com/mdn/content/issues/34696
My understanding is that this updates MediaCapabilities.decodingInfo()
with an additional property added to the configuration
argument object called keySystemConfiguration
- which defines config for encrypted media, and which can be used in a secure context in the window thread only. It also causes the returned object to have a new property keySystemAccess
(a MediaKeySystemAccess
that can be used for decoding the media.
About right?
The spec says the returned object should also include a property configuration
that contains the original configuration passed in - that does not appear to be in the returned object on FF right?
The question I have is whether anyone else has implemented this? It looks like Chrome might have a precursor version in Chrome 80 based on:
- https://chromestatus.com/feature/5765900795904000
- https://googlechrome.github.io/samples/media-capabilities/decoding-info-eme
- https://developer.chrome.com/blog/media-updates-in-chrome-75
The examples show the configuration property has keySystem
and a robustness parameter. Do you know if they are updating to match the new spec. What about Safari?

Yes, we haven't implemented that part, and so do other browser vendors.

- https://chromestatus.com/feature/5765900795904000

Chromium-based browsers already support this feature as you know, and I haven't heard any news from Safari. Our and Chromium's implementation are the same, both of them matches the current spec.
