[dependabot-preview]

Bumps webrtc-adapter from 6.4.4 to 7.7.0.

Release notes

Sourced from webrtc-adapter's releases.

v7.2.5

• stop changing getStats function signature in Chrome+Firefox
• ignore addIceCandidate({candidate: ""}) in Chrome and Firefox
• use named functions for shims, increasing readability
• point to es5 dist/adapter.js in package.json main
• fix pc.sctp in plan-b mode

shim connectionState

shim RTCPeerConnection.connectionState and related events.

Fix issue with usage of this in addTrack/removeTrack shim

This release fixes an issue with the usage of this in the addTrack/removeTrack shims. Thank you to @Krivega for contributing PR #917.

ES6 all the things

• adapter is now using ES6. This is a major change and probably broke stuff
• navigator.getDisplayMedia shim is gone. Only navigator.mediaDevices.getDisplayMedia survives.
• getStreamById is gone from Safari shim. It is gone from Chrome too.
• removed lots of cruft from Chrome and Firefox shims. If you need support for browsers which are older than two years stick with the old version

getDisplayMedia moved to navigator.mediaDevices

accomodate for the move
