GetMovieAudioVolumeLevels:
This API returns the current volume meter levels of the movie. It can return both average power
levels and peak hold levels. whatMixToMeter must be set to kQTAudioMeter_DeviceMix. Either
QTAudioVolumeLevels parameter may be nil. If non-nil, each must have its numChannels field set to
the number of channels in the movie's device mix, and must be allocated large enough to hold levels
for all those channels. See kQTAudioMeter_DeviceMix above to see how to determine the channel
layout of the device mix. The levels returned are measured in decibels, where 0.0 means full volume,
-6.0 means half volume, -12.0 means quarter volume, and -inf means silence.
