* HTMLMediaElement::seekToNextFrame() is a Mozilla experimental feature.
|
|
*
|
|
* The SeekToNextFrame() method provides a way to access a video element's video
|
|
* frames one by one without going through the realtime playback. 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.
