Under zero-hertz mode, provided that a frame arrived to the VideoStreamEncoder, the receiver may experience up to a second between incoming frames. This results in key frame requests getting serviced with that delay, which is undesired. What's worse is also the fact that if no frame ever arrived to the VideoStreamEncoder, it will not service the keyframe requests at all until the first frame comes. This change introduces VideoSourceInterface::RequestRefreshFrame which results in a refresh frame being sent from complying sources. The method is used under zero-hertz mode from the VideoStreamEncoder when frames didn't arrive to it yet (with changes to the zero-hertz adapter). With this change, when the frame adapter has received at least one frame, it will conditionally repeat the last frame in response to the key frame request. go/rtc-0hz-present Bug: chromium:1255737 Change-Id: I6f97813b3a938747357d45e5dda54f759129b44d Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/242361 Reviewed-by: Erik Språng <sprang@webrtc.org> Reviewed-by: Niels Moller <nisse@webrtc.org> Reviewed-by: Henrik Boström <hbos@webrtc.org> Commit-Queue: Markus Handell <handellm@webrtc.org> Cr-Commit-Position: refs/heads/main@{#35562}
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
