MediaController events are also very similar to HTMLMediaElement events, as shown in
Table 8
. They key difference is, again, an event is only triggered when conditions are met for
all of the slaved media resources. Take an event like
waiting.
It's triggered in the HTMLMe-
diaElement when playback is blocked because the next frame isn't currently available, but the
user agent is expecting it to become available. With the MediaController,
waiting
generally
means the same thing, but it comes about because one of the media resources is blocked, not
necessarily because all the media resources are blocked.
The MediaController adds new meaning to the old phrase: all for one, and one for all.
