  "message": "Introduce MediaEngineReference for managing access on the worker thread\n\nThis encapsulates direct, non-const, access to the media engine and the\nreference counting via a new class, MediaEngineReference.\n\nThis change introduces `ConnectionContext::MediaEngineReference`, a new\nRAII wrapper class to manage the media engine\u0027s lifetime and access.\n\nThe `MediaEngineReference` class:\n* Automatically handles reference counting in its constructor\n    and destructor.\n* Provides a `media_engine()` accessor that `DCHECK`s the call\n    is on the worker thread, centralizing thread-safety enforcement.\n\n`PeerConnection`, `PeerConnectionFactory` (for AEC dumps), and\n`RtpTransceiver` are all updated to use `MediaEngineReference` instead\nof calling the manual ref-counting methods.\n\nAdditionally, a new `ConnectionContext::is_configured_for_media()`\nmethod is introduced to replace checks for `context_-\u003emedia_engine()`\nwhen determining if media is enabled.\n\nThis is a follow up to recent media engine changes that more tightly\ncontrol the lifetime of the media engine as well as divide access to\nconst and non-const methods. A follow up to this CL could be to split up\nthe media engine interfaces to make the actual work that runs on the\nworker thread be owned by a separate interface from the const methods.\nThen there\u0027d be no need for the Init/Terminate methods and the design\nwould be a bit clearer.\n\nBug: webrtc:42224720\nChange-Id: Idd7bd9a143ee00d1939f0bac93c877253ac57e09\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/410922\nCommit-Queue: Tomas Gunnarsson \u003ctommi@webrtc.org\u003e\nReviewed-by: Markus Handell \u003chandellm@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#45971}\n",
