This makes the implementation in line with the existing X11 implementation: https://source.chromium.org/chromium/chromium/src/+/main:third_party/webrtc/modules/desktop_capture/linux/x11/screen_capturer_x11.cc;l=240-243 The issue I am observing on slightly slower machines with 4k monitor is that the frames tend to go back in time. I believe this happens when the shared frame queue is full and has its frame shared. When that happens, we still end up calling MoveToNextFrame and doing so we will wrap around the queue and if the capturer captures a frame again, it sees an older frame. This is causing screen glitches. This CL normalizes the implementation with X11 (which is known to work fine) and moves to next frame and always uses it. This helps to keep the current_frame_ in sync for the caller / capturer and the capturer will then always see the video moving forward. On the same machine, these screencasts were taken: Without this fix: https://youtu.be/7Toi8dL5eYw With this fix: https://youtu.be/LOE8Si5iOuQ Bug: chromium:1291247 Change-Id: I51d3d700d3417d31371b12a94f445fc7b530cf73 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/278700 Reviewed-by: Alexander Cooper <alcooper@chromium.org> Commit-Queue: Salman Malik <salmanmalik@chromium.org> Cr-Commit-Position: refs/heads/main@{#38342}
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.
