### APIs

- {{domxref('RTCRtpReceiver.getParameters()')}} and {{domxref('RTCRtpSender.getParameters()')}} are now supported, returning an object that describes the current codecs used for the encoding and transmission of media on the receiver and sender tracks, respectively. ([Firefox bug 1534687](https://bugzil.la/1534687)).
- {{domxref('MediaKeys.getStatusForPolicy()')}} is now supported for checking whether the CDM module, which is used to decrypt DRM protected content, would allow the presentation of encrypted media data for a "hypothetical" key based on specified policy requirements such as the HDCP version supported by the system.
This provides an application with a simple mechanism to know in advance whether playback at the optimal resolution will be allowed, without having to create a media key session or fetch a real license. ([Firefox bug 1878714](https://bugzil.la/1878714)).
