Replicating UMP time markers

[Geoff Pearson]

Another question!!

In AE, how do I query the status of an audio clip?

For example, I am trying to replace...

if mediaplaying of group "shutdown"
Stop media player UMP "shutdown"

I now have the mp3 clip "shutdown" playing using the PPac pgSoundControl but haven't figured out how to determine its status.

pgSoundControl() is the companion function to pgSoundLoader(). It allows you to set/get the playhead position and the status of any audio loaded with pgSoundLoader(). The popup help provides all the details to help you set up your audio queries. If you are getting a property of an audio, you must set a variable to store the return value from the function and then check the returned value to determine how your Actions should handle the result.

There are several ways to get the status of an audio using pgSoundControl().

1. Set action =

   "status"

   
   Returns undefined or 0 for audio that is not playing and 1 for an audio that is playing. Other possible values indicated in the popup help are 2 or 3, but very rarely are these ever returned.
2. Set action =

   "isPaused"

   
   Returns true (paused) or false (or playing)

Example:

GET STATUS of audio named "myAudio"

When this button is clicked without loading

"myAudio"

first, it displays the alert string "undefined" which is the same as 0 or false.
When the

"myAudio"

is playing or paused, it returns 1 indicating the audio is loaded and available for manipulation by pgSoundControl().
When the

"myAudio"

has finished playing, it returns 0.
I prefer to catch the "end" value in the on user event if that is all that is needed. Otherwise check the

isPaused

property.

Of course, pgSoundControl() can remotely get/set playhead position, get/set volume too, unload audio files, toggle the pause/play state, stop/resume, etc. It's all in the popup documentation.
