This is a reland of commit e20fbb00d0e0219b710da24664e81a10b12c703a which failed due to CHECK failing on monitor_id in DxgiDuplicatorController::GetDeviceScaleFactor(). This has now been fixed in this CL by removing the check for greater than 0 and instead returning std::nullopt. Original change's description: > Get DeviceScaleFactor for the captured monitor/screen > > Accesses DeviceScaleFactor using the windows API > GetScaleFactorForMonitor and adds it to the DesktopFrame. In a follow-up > CL, this value is propagated to > DesktopCaptureDevice::Core::OnCaptureResult where it is added to the > frame metadata. > > In a follow-up CL, add RegisterScaleChangeEvent to get notified whenever > the device scale factor changes. > > Design doc: go/expose-captured-surface-resolution > > Bug: chromium:383946052 > Change-Id: I363af33c569419d95ddf31a0cc2f9cecf6fb0c7b > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/374344 > Reviewed-by: Henrik Andreassson <henrika@webrtc.org> > Reviewed-by: Mark Foltz <mfoltz@chromium.org> > Commit-Queue: Palak Agarwal <agpalak@google.com> > Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#43827} Bug: chromium:383946052 Change-Id: Iffcc889b9a560695302f71623e3e929ecb2489fb Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/376061 Commit-Queue: Palak Agarwal <agpalak@google.com> Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> Reviewed-by: Henrik Andreassson <henrika@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43832}
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
