Нужно ли освободить готовый буфер от OpenSL ES Audio Player?

Question

только для подтверждения.Когда аудиоплеер, созданный через OpenSL ES для Android, заканчивает воспроизведение буфера, это буфер автоматически освобождается от мусора?Или мне нужно освободить буфер самостоятельно?

Если это последний, я мог бы использовать некоторую помощь.Но, как сейчас, я не буду публиковать какой-либо код, пока мне не скажу, что мне нужно сделать это сам ...

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.
