Description Thomas Steiner 2020-05-15 02:22:17 PDT
HTMLVideoElement.requestVideoFrameCallback() allows web authors to register a callback which runs in the rendering steps when a new video frame is sent to the compositor. This is intended to allow web authors to do efficient per-video-frame processing of video, such as video processing and painting to a canvas, video analysis, or synchronization with external audio sources. This API has support from Mozilla (https://mozilla.github.io/standards-positions/#requestVideoFrameCallback) and is already implemented in Chromium.
