This change introduces a new FrameCadenceAdapter class which takes the role of being a VideoFrameSinkInterface<> instead of VideoStreamEncoder. The FrameCadenceAdapter will see its functionality grow in future CLs and eventually enable screenshare capture sources to have zero hertz as the minimum capture frequency. This CL moves logic related to UMA collection and constraints into the adapter. The adapter has two major modes. Future functionality is planned to be added under the WebRTC-ZeroHertzScreenshare field trial. Unit tests are added that verify passthrough operation when WebRTC-ZeroHertzScreenshare isn't specified or disabled. Just specifying the WebRTC-ZeroHertzScreenshare field trial isn't enough to activate the feature, but the caller has to additionally configure screen content type, minimum FPS 0, and maximum FPS > 0 for the new mode. go/rtc-0hz-present Bug: chromium:1255737 Change-Id: I1799110ed40843152786ad80df10acfb83a608b1 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/236682 Commit-Queue: Markus Handell <handellm@webrtc.org> Reviewed-by: Henrik Boström <hbos@webrtc.org> Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> Reviewed-by: Stefan Holmer <stefan@webrtc.org> Reviewed-by: Niels Moller <nisse@webrtc.org> Cr-Commit-Position: refs/heads/main@{#35315}
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.
