Emit a 'tap' events when touch event support gets detected. This gets used to support toggling the controls through a tap on the video. They get enabled because every sub-component would have extra overhead otherwise.
Fires:
Listens to Events:
- Component#event:touchstart
- Component#event:touchmove
- Component#event:touchleave
- Component#event:touchcancel
- Component#event:touchend
-
emulateTextTracks()
-
Emulate texttracks
-
This function reports user activity whenever touch events happen. This can get turned off by any sub-components that wants touch events to act another way.
Report user touch activity when touch events occur. User activity gets used to determine when controls should show/hide. It is simple when it comes to mouse events, because any mouse event should show the controls. So we capture mouse events that bubble up to the player and report activity when that happens. With touch events it isn't as easy as
touchstart
andtouchend
toggle player controls. So touch events can't help us at the player level either.User activity gets checked asynchronously. So what could happen is a tap event on the video turns the controls off. Then the
touchend
event bubbles up to the player. Which, if it reported user activity, would turn the controls right back on. We also don't want to completely block touch events from bubbling up. Furthermore atouchmove
event and anything other than a tap, should not turn controls back on.Listens to Events:
- Component#event:touchstart
- Component#event:touchmove
- Component#event:touchend
- Component#event:touchcancel

Localize a string given the string in english.

to be included.Currently, it is used for the progress bar timing.
{ "progress bar timing: currentTime={1} duration={2}": "{1} of {2}" }
