Except for a use of std::multimap (for which there currently is no drop-in replacement), use webrtc::flat_map and flat_set for increased performance. The number of ssrcs/mids/payload types/etc is likely to be small and is generally updated very rarely, but looked up a lot. RtpDemuxer::ResolveSink's use of std::map represents about 0.6% CPU in heavily loaded media servers. It does quite a few map lookups, and by taking advantage of the increased cache locality of the flat_map and flat_set containers, performance should be increased. A previous attempt to use std::unordered_map failed in change 216243, which was reverted. This is the second attempt.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
