Summary: Provides an interface for receiving frame performance timing including composites happening on a separate thread/process. This can be used to calculate measures of smoothness that incorporate the effect of async pan and zoom and off-main thread animation.
Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1158032 Link to standard: https://w3c.github.io/frame-timing/ Platform coverage: all platforms Estimated or target release: Firefox 43 although we might hold off shipping depending on the state of the spec at that time (there has been discussion of replacing the buffer-based interface with an observer interface). Preference behind which this will be implemented: dom.enable_frame_timing DevTools bug: No specific bug yet but the DevTools team is aware of our intention to implement and indicated they could use this API. Other browser support: Blink: in development, soon to reach Canary.[1] [1] https://code.google.com/p/chromium/issues/detail?id=120796#c53 Thanks, hiro _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
