Same to the cursor position. This > causes trouble when we check the relative position of image and cursor > when there are multiple monitors with different DIP setting connected. > > This cl proposed a solution to use DIP pixel for any location info, > i.e. top-left of a frame and cursor position. Also propose a method to > get the current scale factor of a window across multiple monitors. And > save the current scale factor in DPI of the capture frame. > Then we can check relative position of cursor and frame correctly > in DIP pixel and compose them in physical pixel. > > Bug: webrtc:9178 > Change-Id: I3c076aeac2d6f2c1f63d000d7fff03500aa375ac > Reviewed-on: https://webrtc-review.googlesource.com/71621 > Reviewed-by: Jamie Walch <jamiewalch@chromium.org> > Reviewed-by: Zijie He <zijiehe@chromium.org> > Commit-Queue: Brave Yao <braveyao@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#23263} Bug: webrtc:9178 Change-Id: I97d9150f7b9a4ed6671733b75613ea9c315d5c1d Reviewed-on: https://webrtc-review.googlesource.com/77481 Reviewed-by: Zijie He <zijiehe@chromium.org> Commit-Queue: Brave Yao <braveyao@webrtc.org> Cr-Commit-Position: refs/heads/master@{#23289}
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
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
Authoritative list of directories that contain the native API header files.
