Playing of sound is asynchron every time.
|
|
|

@attention We must hold us alive by ourself ... because we use async. vcl sound player ... but playing is started
|
|
in async interface call "dispatch()" too. And caller forget us immediately. But then our uno ref count
|
|
will decreased to 0 and will die. The only solution is to use own reference to our implementation.
|
|
But we do it for really started jobs only and release it during call back of vcl.

@short try to detect file (given as argument included in "lDescriptor")
|
|
@descr We try to detect, if given file could be handled by this class and is a well known one.
|
|
If it is - we return right internal type name - otherwise we return nothing!
|
|
So call can search for another detect service and ask him too.
|
|
|
|
@attention a) We don't need any mutex here ... because we don't use any member!
|
|
b) Don't use internal player instance "m_pPlayer" to detect given sound file!
|
|
It's not necessary to do that ... and we can use temp. variable to do the same.
|
|
This way is easy - we don't must synchronize it with currently played sounds!
|
|
Another reason to do so ... We are a listener on our internal ma_Player object.
|
|
If you would call "IsSoundFile()" on this instance, he would call us back and
|
|
we make some unnecessary things ...
|
