So, it lets * authors use "frame" as unit to access the video element's underlying data, * instead of "time". * * The SeekToNextFrame() is a kind of seek operation, so normally, once it is * invoked, a "seeking" event is dispatched. However, if the media source has no * video data or is not seekable, the operation is ignored without filing the * "seeking" event. * * Once the SeekToNextFrame() is done, a "seeked" event should always be filed * and a "ended" event might also be filed depends on where the media element's * position before seeking was. There are two cases: * Assume the media source has n+1 video frames where n is a non-negative * integers and the frame sequence is indexed from zero. * (1) If the currentTime is at anywhere smaller than the n-th frame's beginning * time, say the currentTime is now pointing to a position which is smaller * than the x-th frame's beginning time and larger or equal to the (x-1)-th * frame's beginning time, where x belongs to [1, n], then the * SeekToNextFrame() operation seeks the media to the x-th frame, sets the * media's currentTime to the x-th frame's beginning time and dispatches a * "seeked" event. * (2) Otherwise, if the currentTime is larger or equal to the n-th frame's * beginning time, then the SeekToNextFrame() operation sets the media's * currentTime to the duration of the media source and dispatches a "seeked" * event and an "ended" event. */ partial interface HTMLMediaElement { [Throws, Pref="media.seekToNextFrame.enabled"] Promise<void> seekToNextFrame(); }; /* * This is an API for simulating visibility changes to help debug and write * tests about suspend-video-decoding. */ partial interface HTMLMediaElement { [Pref="media.test.setVisible"] void setVisible(boolean aVisible); };
