I have main form that start these 2 threads. I must load plug in one time inside main form o inside the first or the second thread ?

The BASS_PluginLoad call can be made in any thread.

Administrator, can you confirm that i must load call bass_plugin only one time if i have two download internet radio ?

And, if i unload basswma for the first internet radio it unload for the second internet radio too ?

All BASS functions are 'static'!
As such it doesn't really matter in which thread (either the UI thread or any other thread you call those function).
Except for "BASS_Init", which should be called in the main UI Thread.

However, good practice is to invoke all your one-time things in the main UI thread at the beginning  of the application (like initializing the audio device, loading any plugins, setting any BASS config options etc.).
Once all this is done, you might create any number of (worker) threads to perform any kind of processing.
E.g. calling BASS_StreamCreateURL multiple times for different streams might easily go into dedicated threads.

Yes to both questions. If you call BASS_PluginLoad multiple times with the same DLL (eg. BASSWMA.DLL), the extra calls will fail with a BASS_ERROR_ALREADY error. And if you call BASS_PluginFree to unload a plugin, all streams that are using that plugin will automatically be freed.

Thank you very much for your informations.
I have another question, if I have two internet radio so :

the first radio is wma type and
the second radio is aac type,

i must load wma and aac plugin both ?
on main form ? or wma plugin inside first thread that download the first radio and aac plugin inside the second thread that download the second radio ?

[Ian @ un4seen]

Yes, if you want to play WMA and AAC streams, then you will need to load both BASSWMA and BASS_AAC (unless Media Foundation codecs are available). As mentioned earlier, it doesn't really matter what thread you make the BASS_PluginLoad calls in. I would suggest loading the required plugins once during initialization and then just leaving them loaded, ie. don't bother with BASS_PluginFree.
