Support and compatibility

VAST event compatibility

Fully supported

All video players must fire the callbacks that trigger the following events:

complete, creativeView, firstQuartile, impression, midpoint, pause, resume, rewind, start, thirdQuartile

Optionally supported

Because Android applications do not typically control the device's volume, the mute and unmute events are generally not fired.
