Tarek Ziadé c48befbb9c Bug 1542674 - Make Media debug info machine parsable r=padenot,smaug,jya
This patch structurizes the media debug information via webidl dictionaries
that are returned by HTMLMediaElement::GetMozRequestDebugInfo() and
MediaSource::GetMozDebugReaderData().

/*
* 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.
