Um buffer acabado de um player de áudio OpenSl ES precisa ser libertado?

Question

Apenas para confirmação.Quando um reprodutor de áudio, criado via OpenSl ES para Android, acaba jogando um buffer, é que o buffer é automaticamente libertado pelo coletor de lixo?Ou eu preciso libertar o amortecedor?

Se for este último, eu poderia usar alguma ajuda.Mas como por enquanto, não vou postar nenhum código até ser informado de que eu preciso fazer isso sozinho ...

Answer 1

The buffer queue doesn't actually allocate buffer memory itself (or need to free it), you pass in pointers to memory you have allocated via the 'enqueue' function. You will need to free the memory you allocated when you're finished playing buffers.

As OpenSL ES is a native library in C++, it knows nothing of garbage collection, any memory you allocate for the API must be freed by you, and objects you create must have 'destroy' called on them to clean up internal memory.

Answer 2

As the previous poster said, you call Enqueue with a buffer you have created previously. I'd point out, however, that unless you're playing only one audio event once in your app, you should probably keep re-using your audio buffers to avoid GC altogether - the beauty of C!

Also check out the Android OpenSL ES doc concerning Destroying your interfaces once your done with them, that has to be done manually.
